BACKGROUND
1. Technical Field
The present disclosure generally relates to quality control in field service applications. In particular, the present disclosure is directed to a work order approval system and method of performing quality control in field service applications, such as locate operations.
2. Description of the Related Art
Field service applications may be any application in which companies dispatch technicians and/or other staff into the field in order to perform, for example, certain installations, services, and/or repairs. Field service applications may exist in industries, such as, but not limited to, network installations, utility installations, security systems, construction, medical equipment, heating, ventilating, and air conditioning (HVAC), and the like.
In certain field service applications, there may be an associated work order for each field call. These work orders are hereafter referred to as tickets. The ticket information may include, for example, the physical address or other location information to which the field technician is dispatched, the type of installation service, and/or repair that is requested. Depending on the field service application, certain processes may exist for verifying certain aspects of the installations, services, and/or repairs that are to be performed by the field service technicians according to the ticket information. Since there may be numerous field technicians, each of whom are assigned numerous tickets, implementing and performing meaningful oversight and quality control activities in a timely fashion may be difficult. As a result of the limited quality control activities in certain field service applications, customer satisfaction may be adversely affected. Additionally, the time, effort, and cost that is associated with re-performing work in the field or with correcting and/or improving poorly performed field calls may be unacceptable.
Consequently, a need exists for methods of providing oversight and quality control in field service applications in order to improve customer satisfaction, to identify and reduce the number of poorly performed tickets, and to improve visibility into distributed workforce operations. More specifically, a need exists for improved approaches to quality control in the underground facility locate industry in order to improve customer satisfaction and to reduce the risk of damage to underground facilities due to poorly performed locate operations.

Examples of facilities include, but are not limited to, oil, gas, water, sewer, power, telephone, data transmission, cable TV, and/or internet services.
The present disclosure includes a method and system of performing oversight and quality control in field service applications, such as locate operations, and ticket approval systems. The ticket approval system of the present disclosure provides a mechanism by which approvers and/or managers may review the quality of locate operations in real time and/or within a certain amount of time (e.g., within one day) of the locate operation. In particular, a ticket approval software application of the present disclosure provides a graphical computerized mechanism for viewing the information, such as images, that is associated with locate operations, which allows for a rapid and efficient processing of tickets. Examples of images include, but are not limited to, digital images, aerial images, and so on. In doing so, approvers and/or managers may assess the quality of each locate operation in a time efficient manner. Based on the assessment, locate operations may be categorized in a variety of ways, for example: (1) approved, no further action needed; (2) satisfactory, but the locate technician needs coaching or training; or (3) unsatisfactory, the ticket needs quality control (QC) action. While approvers may be required to assess all tickets of the locate technicians under their supervision, a random subset of tickets may be selected for higher managerial review, adding a further level of quality assurance.
The ticket approval system of the present disclosure maintains a numerical count of approved tickets, coaching referrals, and QC referrals. In the case of QC referrals, the ticket may require immediate dispatch to the original locate technician or a QC technician. QC referrals may be considered high priority and, therefore, routed to the next available time slot of the locate or QC technician, in order to correct defects in a timely manner.
The method and system of the present disclosure may be used in a locate operation. Man-made objects, such as facilities, and in particular, underground facilities (e.g., gas, water, sewer, power, telephone, and cable television lines), are susceptible to damage from various things, such as from excavation. Local and federal laws may require that notification be given to facility owners that own underground facilities in an excavation area before any excavation takes place. If such notification is received, the facility owner typically locates and marks the location of the underground facilities. By way of example, the facility owner may use a ticket approval system for and method of performing oversight and quality control during a locate operation, as described herein.
Locate operations may be performed, for example, by the facility owner. A marking dispenser system is typically used to create locate marks. Paint is commonly used as the marking material, and it is typically applied using a marking device. The color of the marking material is typically chosen based on the type of underground facility that is being marked (e.g., red paint for a power line).
Protocols may exist for verifying certain aspects of locate operations that are performed by locate technicians. For example, for each locate operation, the locate technician may be required to provide certain evidence (e.g., photographs) that may be used in order to verify (against the original ticket) the actual address at which the locate operation was performed versus the requested address, the actual locate operations that were performed versus the requested locate operations, and to provide proof that the locate operation was actually performed (i.e., proof of “locate marks”).
The system of the present disclosure provides a mechanism by which approvers and/or managers may review the quality of locate operations in real time and/or within a certain amount of time (e.g., within one day). In particular, a ticket approval software application of the present disclosure provides a graphical computerized mechanism for viewing the information, for example, digital information, markings, and images, that is associated with the locate operations, which allows rapid and efficient processing of tickets.
Further, approvers and/or managers may quickly assess the quality of each locate operation. Based on the assessment, locate operations may be categorized as, for example, (1) approved, no further action needed, (2) satisfactory, but the locate technician needs coaching or training, or (3) unsatisfactory, the ticket needs quality control (QC) action. While approvers may be required to assess all tickets of the locate technician under their supervision, a random and/or rules-based subset of tickets may be selected for higher managerial review, adding a further level of oversight and quality assurance.
The ticket approval system of the present disclosure maintains, for example, a numerical count of approved tickets, coaching referrals and QC referrals. In the case of QC referrals, the ticket may require immediate dispatch to the original locate technician or a QC technician. QC referrals may be considered high priority and, therefore, routed to the next available time slot of the locate technician or QC technician in order to correct any defects prior to the start of excavation.
Referring to FIG. 1, a functional block diagram of a system 100 for performing oversight and quality control in locate operations is provided. System 100 may include a locate service provider 110, which may be any facility owner. Additionally, system 100 may include a work management server 112, which is maintained and operated by locate service provider 110, and which may be any local or centralized computing device, including a processing unit 150, a memory 152, and a communication interface 154, that is capable of hosting an application such as a ticket approval application 130, as discussed further below. In implementation, work management server 112 may be a networked application and/or web server.
Personnel that are associated with system 100 may include, but are not limited to, managers 114, QC approvers 116, approvers 118, QC technicians 120, and locate technicians 122 of locate service provider 110. Managers 114 may be high-level managers of locate service provider 110, including directors and/or company executives of locate service provider 110 that oversee QC approvers 116, approvers 118, QC technicians 120 and locate technicians 122. Managers 114 may interact with the ticket approval application 130 via a display device 156A and a user input device 158A coupled to the work management server 112. It is contemplated that managers 114, QC approvers 116, approvers 118, QC technicians 120 and other locate technicians 122 may also serve in a QC capacity according to the present disclosure.
QC approvers 116 may be the individuals that are responsible for processing any QC referrals and to whom QC technicians 120 may report. QC approvers 116 may interact with the ticket approval application 130 via a display device 156B and a user input device 158B coupled to the work management server 112. QC technicians 120 are technicians that are dispatched into the field for performing QC activities. Approvers 118 may be the direct supervisors of locate technicians 122. Approvers 118 may interact with the ticket approval application 130 via a display device 156C and a user input device 158C coupled to the work management server 112. Further, managers 114, QC approvers 116, and/or approvers 118 may be the personnel of the customers of locate service provider 110. For example, managers 114, QC approvers 116, and/or approvers 118 may be service managers of the customers of locate service provider 110 who wish to verify the quality of the workflow of locate service provider 110.
Referring again to FIG. 1, system 100 may include various image capture mechanisms 124 by which QC technicians 120 and locate technicians 122 provide images of the dig area while performing locate operations. In an example, image capture mechanism 124 is a consumer or professional grade digital still or video camera. In another example, image capture mechanism 124 is the device for providing an electronic manifest of underground facility locate marks that is described in U.S. patent application Ser. No. 12/029,732 (the “'732 patent application”), entitled “Electronic manifest of underground facility locate marks,” that is incorporated by reference herein in its entirety.
Image capture mechanism 124 may be used to obtain an image used to verify the address of the locate operation, to verify the ticket information of the locate operation, and/or to provide proof that the locate operation was actually performed. For example, image capture mechanism 124 may be used to provide an image of something that identifies the location of the dig area, such as an image that shows the street number on a mailbox or on a building or a serial number on a telephone pole. In an exemplary embodiment, certain digital cameras and other devices have geographic or global positioning system (GPS) technology integrated therein, which allows GPS data (i.e., dig area data) to be stored with the image data. In this case, the GPS data may be used as the dig area identifier mechanism. In addition, image capture mechanism 124 may be used to provide an image of a manifest or similar log of the ticket, dig area and locate marks. Furthermore, image capture mechanism 124 may be used to provide an image of the dig area showing locate marks.
Dig area and image (dig area/image) data from image capture mechanisms 124 may be transmitted to and stored on, for example, an image server 126. Each image from image capture mechanisms 124 is associated with a certain ticket. Image server 126 is connected to the work management server 112 via a wired or wireless network 128. Network 128 is, for example, a wide area network (WAN), a local area network (LAN), a telephone network, such as the Public Switched Telephone Network (PSTN) or a cellular network, an Internet connection, an Intranet connection, one or more communication links, and/or a combination of networks. Also, dig area/image data from image capture mechanism 124 may be transmitted directly to work management server 112, as shown by communication link 160.
As noted above, work management server 112 includes a ticket approval application 130 that is implemented via processor-executable instructions executed by processing unit 150 and a database 132 stored in memory 152. Database 132, created and maintained by any suitable database software, stores relationships between, for example, dig area/image data captured by image capture mechanism 124, tickets 134, locate technicians 122 and approvers 118. For example, database 132 may store tickets 134 and associated dig area/image data 136.
In an embodiment, ticket approval application 130 is a software application that provides a graphical computerized mechanism for performing oversight and quality control in a locate operation. Additional details relating to an example of a method of using implemented by the ticket approval application 130 in an oversight and quality control operation are described with reference to FIG. 2. Further, additional details of example GUIs of ticket approval application 130 that may be displayed on one or more of display devices 156A, 156B and 156C are described with reference to FIGS. 3 through 11.
The features of ticket approval application 130 of system 100 of the present disclosure may include, but are not limited to, the following:
a mechanism by which approvers may review tickets rapidly in real time and/or within a certain amount of time (e.g., within one day) from the ticket being executed;
a mechanism by which dig area/image data that is associated with approved tickets may be stored with the appropriate ticket(s) as a part of the archival process;
a mechanism by which a numerical count of approved tickets, coaching referrals, and QC referrals, may be maintained for different levels of the system;
a mechanism by which, while QC approvers 116 may be required to review all tickets of all locate technicians 122 under their supervision, a random and/or rules-based subset of tickets may be selected for higher managerial review, which adds a further level of quality assurance;
a mechanism by which tickets that are tagged for QC referral may be dispatched immediately to the original locate technician, QC technician, and/or another locate technician;
a mechanism by which substantially all tasks that are associated with a QC referral may be completed the same day as dispatched and the manifest is revised to reflect any changes that are made on site;
a mechanism by which QC referrals that are not completed on the same business day as referred may be flagged for managerial review and handling;
a mechanism by which approvers 118 may log and track coaching referrals;
a mechanism by which received data is interrogated against various aspects and limitations, such as time to complete work, cost to complete work, conditions at the work site, time the work was performed (proper or improper time), efficiency with which the work was performed, and the like, to provide exception notifications relating to certain reviewed tickets that can be flagged for review by approver 118;
a mechanism by which coaching opportunities that are not completed within a certain amount of time, for example, within ten business days, may be flagged for managerial review and handling; and
a mechanism by which substantially all documentation may be auto-archived, for example, in database 132 of work management server 112 as well as in employee personnel files (e.g., human resources files) for use, for example, with tracking employee information and performance evaluation scoring.
Turning now to FIG. 2, a flow diagram of an example of a method 200 of performing oversight and quality control in a locate operation using system 100 is presented. Method 200 may include, but is not limited to, the following steps, which may be implemented in any order.
At step 210, the locate technician completes the ticket and provides dig area data. For example, locate technician 122 is assigned a certain ticket and is dispatched to a specific dig area to perform a locate operation. In the process of performing the locate operation, locate technician 122 captures the required dig area/image data via image capture mechanism 124. In an example, when image capture mechanism 124 is a digital camera, locate technician 122 provides a digital photograph that shows the street number on a building, another digital photograph of the paper manifest, and another digital photograph of the dig area, showing locate marks. Additionally, when image capture mechanism 124 is the device and method of the '732 patent application, the images of the dig area, showing locate marks, are in the form of an image of the dig area that has locate marks electronically overlaid thereon. These locate marks denote the presence of facilities. The device and method of the '732 patent application provide alternative mechanisms for automatically providing dig area identification information and manifest information in electronic form for importing into ticket approval application 130.
Upon completion of the locate operation, the dig area/image data of image capture mechanism 124 may be transmitted to image server 126 or directly to work management server 112. In doing so, the dig area/image data is accessible to ticket approval application 130. Additionally, an association is formed between the dig area/image data and the ticket. This association between the dig area/image data and the ticket is maintained throughout the steps of the oversight and quality control method of the present disclosure.
At step 212, an approver opens the ticket approval application 130 and selects a certain locate technician and ticket for quality control review. Each approver 118 is responsible for a certain group of locate technicians 122. This approver-specific group of locate technicians 122 may be called an approver group.
By way of example, FIG. 3 illustrates an example of an approver inbox GUI 300 for use in system 100 of the present disclosure. Approver inbox GUI 300 may be the user interface that is presented to approver 118 upon logging into ticket approval application 130. Approver inbox GUI 300 displays one or more locate technician windows 310 (310a-310i), whereby each of locate technician windows 310 is associated with certain locate technician 122 of the approver group. A display area of approver inbox GUI 300 may indicate the total number of new tickets, coaching referrals and QC referrals for the approver group. Approver 118 is able to select a new ticket via a new ticket icon 312 and is able to select tickets that have been referred for QC via a quality controlled ticket icon 314. Further, approver 118 is able to select tickets that have been referred for coaching via a coached ticket icon 316. In an example, approver 118 selects new ticket icon 312 of locate technician window 310a. Ticket approval application 130 reads in the associated ticket information and dig area/image data from tickets 134 and dig area/image data 136 of database 132.
At step 214, approver 118 reviews the dig area/image data of the selected ticket. For example, approver 118 reviews the ticket of locate technician window 310a that was selected at step 212.
By way of example, FIG. 4 illustrates an approver image viewer GUI 400 for use in the ticket approval system of the present disclosure. Approver image viewer GUI 400 may include an image display area 410, multiple text display fields, such as a TICKET MANIFEST display field, and a WORK PERFORMED display field. Other information may be displayed, such as the ticket number, locate technician name, ticket details, locate marks used, and a locate technician signoff field. Additionally, approver 118 may select a navigate back icon 412 in order to return to a previous GUI, may select an approved icon 414 in order to categorize the ticket as satisfactory, may select a QC icon 416 in order to categorize the ticket as unsatisfactory and needing QC action, and may select a coach icon 418 in order to categorize the ticket as satisfactory, but locate technician is in need of coaching.
Approver 118 visually inspects the information that is displayed on approver image viewer GUI 400 and, in particular, compares the dig area image in image display area 410 with the information in the TICKET MANIFEST display field and a WORK PERFORMED display field.
If approver 118 determines that substantially all aspects of the locate operation are satisfactory, approver 118 selects approved icon 414 and method 200 proceeds to step 216. For example, if the information in the WORK PERFORMED display field and the markings that are shown at the dig area in image display area 410 satisfactorily match the information in the TICKET MANIFEST display field, approved icon 414 may be selected and method 200 proceeds to step 216. In this case, the risk of a locate error and damage to facilities during excavation is diminished.
If approver 118 determines that the locate operation itself is satisfactory, but certain aspects of the information that is provided by locate technician 122 needs improvement, approver 118 selects coach icon 418, which generates a coaching referral and method 200 proceeds to step 218. For example, the locate operation is satisfactory when the information in the WORK PERFORMED display field and the markings that are shown at the dig area in image display area 410 sufficiently match the information in the TICKET MANIFEST display field. In this case, risk of a locate error and damage to underground facilities during excavation may be low. However, certain details of the markings may need to improve. For example, a less than desirable anchor point has been marked. This may result in a minor inaccuracy, while not presenting a risk of damage during excavation. In this example, locate technician 122 may need training with regard to selecting anchor points.
If approver 118 determines that important aspects of the locate operation are unsatisfactory, approver 118 selects QC icon 416, which generates a QC referral and method 200 proceeds to step 224. In an example, a gross error that may prompt the need for QC action may be when the TICKET MANIFEST calls for gas, power, and water lines to be located and marked, yet the information in the WORK PERFORMED display field and site image in image display area 410 shows that only the gas and power lines were marked. In this example, because the water lines were not marked, there may be an increased risk of damage to the water lines during excavation, and immediate corrective action may be required.
Further to the QC referral example, FIG. 5 illustrates an example of a QC referral popup window 500 for use in the ticket approval system of the present disclosure. QC referral popup window 500 shows a selection of various reasons for which a QC referral may be generated as well as a text box for entering notes. For the above example, QC referral popup window 500 shows that the reason for referral is “Member underground facility not seen as noted on manifest” and clarifying notes are shown. QC referral popup window 500 includes a submit QC referral icon 510 and a cancel QC referral icon 512. QC referral popup window 500 is not limited to the selections shown in FIG. 5 and may be designed to include any content.
Upon step 216, the ticket approval process is completed. The dig area/image data that is associated with approved tickets may be stored with the appropriate ticket(s) as a part of an archival process. The numerical count of approved tickets for the entire system, for each approver group of locate technicians 122 and for individual locate technician 122, may be updated and stored.
At step 218, the coaching referral is routed to the approver's inbox. For example, the coaching referral that is generated at step 214 may be maintained in the inbox of originating approver 118 for a certain period of time, such as, for example, ten business days. This allows for coaching schedules to be developed and completed in a timely manner.
At step 220, approver 118 performs the coaching activity with locate technician 122. For example, approver 118 steps through one or more coaching referrals in approver's 118 inbox for targeted locate technician 122 and performs one or more coaching activities, according to the contents of each coaching referral.
At step 222, locate technician 122 and approver 118 sign off on the coaching activities as acknowledgement that the coaching activity has been completed. A positive report of completing the coaching activities may be logged, for example, in the personnel file of locate technician 122. The one or more coaching referrals may then be removed from the inbox of approver 118.
At step 224, the ticket that is the subject of QC referral of step 214 is routed to a certain QC approver 116 for review. For example, certain QC approver 116 opens ticket approval application 130, views QC approver's inbox and selects a certain locate technician and ticket for which a QC review has been requested.
By way of example, FIG. 6 illustrates an example of a QC approver inbox GUI 600 for use in the ticket approval system of the present disclosure. QC approver inbox GUI 600 may be the user interface that is presented to certain QC approver 116 upon logging into ticket approval application 130. QC approver inbox GUI 600 (610a-610c) displays one or more locate technician windows 610, whereby each locate technician window 610 is associated with certain locate technician 122 and QC referral. A display area of QC approver inbox GUI 600 shows the total number of QC referrals. QC approver 116 is able to select any locate technician window 610, for example, QC approver 116 selects locate technician window 610a. Ticket approval application 130 reads in the associated ticket information and dig area/image data from tickets 134 and dig area/image data 136 of database 132.
At decision step 226, QC approver 116 determines whether to accept or reject the QC referral. For example, QC approver 116 reviews the dig area/image data of the selected QC referral. By way of example, FIG. 7 illustrates a QC approver image viewer GUI 700 for use in the ticket approval system of the present disclosure.
QC approver image viewer GUI 700 may include image display area 410, the TICKET MANIFEST display field, the WORK PERFORMED display field, and other information, as described in approver image viewer GUI 400 of FIG. 4. Additionally, QC approver image viewer GUI 700 includes a navigate back icon 412, an approved icon 414, a QC icon 416 and a coach icon 418, as described in approver image viewer GUI 400 of FIG. 4. QC approver image viewer GUI 700 may also include a text field for displaying notes that were entered by originating approver 118 and additional selections and/or text fields for routing the QC request to original locate technician 122 or to certain QC technician 120.
QC approver 116 visually inspects the information that is displayed on QC approver image viewer GUI 700 and compares the dig area image in image display area 410 with the information in the TICKET MANIFEST display field and a WORK PERFORMED display field. QC approver 116 determines whether QC approver 116 is in agreement with originating approver 118 that the ticket requires QC action.
If QC approver 116 determines that QC action is needed, method 200 proceeds to step 228. If QC approver 116 determines that no QC action is needed, method 200 proceeds to step 234. FIG. 8 illustrates an example of a reject QC popup window 800 for use in system 100. Reject QC popup window 800 may include a text field for entering the reason for rejection as well as a submit QC rejection icon 810 and a cancel QC rejection icon 812.
Optionally, QC approver 116 may determine that no QC action is needed, but coaching is recommended. In this case, method 200 proceeds to step 218. FIG. 9 illustrates an example of a coaching popup window 900 for use in system 100. Coaching popup window 900 may include a text field for entering the reason for coaching as well as a submit coaching request icon 910 and a cancel coaching request icon 912.
At step 228, QC approver 116 routes the ticket to a QC technician for execution. For example, QC approver 116 makes note of the QC action that is needed via QC approver image viewer GUI 700. In the example of step 214, wherein the water lines should have been marked, but were not, QC approver 116 makes a note that the water lines were not marked. QC approver 116 then routes the QC request to original (or alternate) locate technician 122 or to certain QC technician 120 who returns to the dig area to perform the required tasks (e.g., to mark the water lines).
At step 230, QC technician 120 completes the ticket and provides updated dig area/image data. For example, revisiting the dig area in order to perform the tasks that are necessary to satisfy the QC referral. Upon completion of the QC operation, the dig area/image data of the image capture mechanism 124 is transmitted to image server 126 or directly to work management server 112. In doing so, the updated dig area/image data is accessible to ticket approval application 130.
At step 232, approver 118 that originated the QC referral opens approver inbox GUI 300 and reviews the updated ticket via approver image viewer GUI 400. FIG. 10 illustrates another example of approver image viewer GUI 400 that includes additional information. For example, approver 118 is able to view additional notes that have been added along the entire history of the ticket by, for example, QC approver 116 who processed the QC referral and/or QC technician 120 who was assigned to perform the QC operation. Additionally, approver 118 is able to view the original dig area images supplied by original locate technician 122 as well as the new dig area images supplied by QC technician 120. Method 200 returns to step 212 where approver 118 may again review the updated ticket similar to any other ticket.
At step 234, certain QC approver 116 routes the ticket back to the originating approver 118. Method 200 returns to step 212 where approver 118 may again review the ticket similar to any other ticket.
Method 200 is not limited to the operations that are described in FIG. 2. Other operations may occur, such as tracking the status of QC referrals, flagging delinquent QC referrals, tracking the status of coaching referrals, flagging delinquent coaching referrals, tracking the total ticket numbers across the entire service provider, and dashboard reporting. For example, FIG. 11 illustrates an example of a ticket summary GUI 1100 for use in the ticket approval system of the present disclosure. At any time, manager 114 may view the current numerical count of approved tickets, coaching referrals and QC referrals. For example, the ticket summary GUI 1100 shows a summary of these counts, organized by approver groups.
In an alternative embodiment, an example of a real time (or substantially real time) method of performing oversight and quality control in locate operations using the ticket approval system of the present disclosure may be enabled by use of, for example, email infrastructure. In this embodiment, work management server 112 and, in particular, ticket approval application 130 may be accessible via an email application and there may be email communication between entities. Upon completion of a ticket, locate technician 122 may send an email to approver 118 that includes substantially the same content as shown in approver image viewer GUI 400. By use of an email application, approver 118 may process the ticket much the way that has been described in FIGS. 1 through 11, wherein the various GUIs are viewed and processed via the email application. In this embodiment, the workflow is being pushed from locate technicians 122 to approvers 118, rather than being pulled by approvers 118 from locate technicians 122. It is further contemplated that approver 118 will provide a signature, such as, an electronic signature or other indicator to signify completion of the review process.
Similarly, the use of additional communication devices such as mobile telephones, PDAs, portable computers (i.e., laptops and tablet PCs), text messaging and the like are contemplated within all aspects of the present disclosure. By use of one or more of the additional communication devices, any manager/approver/QC technician/locate technician (114, 116, 118 and 120) may process the tickets much the way that has been described in FIGS. 1 through 11, wherein the various GUIs are viewed and processed via any of the one or more additional communication instruments.
Further, it is contemplated that dig area and image data, tickets and related communications according to the present disclosure can be made through wireless interfaces including, for example, an Intranet connection, Internet, Bluetooth® technology, Wi-Fi, Wi-Max, IEEE 802.11 technology, radio frequency (RF), Infrared Data Association (IrDA) compatible protocols, Local Area Networks (LAN), Wide Area Networks (WAN), Shared Wireless Access Protocol (SWAP), combinations thereof, and other types of wireless networking protocols. Additionally, the wireless interface may be capable of capturing signals that reflect a user's intent. For example, the wireless interface may include a microphone that can capture a user's intent by capturing the user's audible statements or commands. Alternatively, the wireless interface may interact with a device that monitors a condition or biological state of the user, such as eye movement, brain activity, heart rate, and/or other subtle signals.
While the ticket approval system and methods of FIGS. 1 through 11 have been described in the context of underground facility locate applications, this is only for exemplary purposes. The ticket approval system and method of the present disclosure may be applicable to any field service or distributed workforce application.
Furthermore, while the ticket approval system and methods of FIGS. 1 through 11 have been described in the context of oversight and quality control of locate operations, the system and methods of the present disclosure are not limited to locate operations involving underground facilities only. The system and methods of the present disclosure are suitable for performing quality control of locate operations, activities to detect or infer the presence or absence of above ground facilities, and any combination thereof. Additionally, the system and methods of the present disclosure can be used in other industries and practices such as, for example, used in the inspection practices of the building and construction fields.
