Title: Service evaluation assessment tool and methodology

Description:
FIELD OF THE INVENTION 
     The present invention relates to a system for providing a service evaluation assessment tool and to a service assessment tool, and is particularly but not exclusively suitable for evaluating the performance of an organisation in relation to service delivery, where the organisation has more than one defined service area providing the overall service delivery. 
     BACKGROUND 
     It is well known for organisations to employ supply chain management to increase organizational effectiveness and achieve such organizational goals as improved customer value, better utilization of resources, and increased profitability. In addition it is known to provide methodologies and instruments for use in measuring supply chain performance. Typical methodologies include measuring, e.g. transport logistics, so as to quantify reliability and responsiveness in order to generate some measure of service effectiveness. One such system is described in US patent application having publication number US 2005-0091001. 
     In this, and indeed other, known systems, performance monitoring is confined to particular areas of the supply chain, and while each area can be measured using a variety of techniques, this does not provide the organization with an overview of how the supply chain fares at each stage, in particular how the delivery of each various stage compares with that of other stages. 
     SUMMARY 
     In accordance with at least one embodiment of the invention, methods, systems and software are provided for operating an integrated data collection platform and for providing an integrated view of relative performance of respective service areas making up an overall service delivery, as specified in the independent claims. This is achieved by a combination of features recited in each independent claim. Accordingly, dependent claims prescribe further detailed implementations of the present invention. 
     More specifically, in accordance with a first aspect of embodiments of the present invention, there is provided a method of presenting one or more sets of service assessment evaluation data, each set of service assessment evaluation data corresponding to services provided by one or by different service providers, the method comprising: 
     providing an integrated data collection platform; and 
     arranging the integrated data collection platform to receive the one or each set of service assessment evaluation data, and, for each said set, using the data collection platform to:
         identify a quantifiable measure of performance for each member of the set; and   present the set of quantified performance measures in an integrated graphical display area such that relative performance between sets of service assessment evaluation data can be established.       

     Thus embodiments of the invention provide an integrated view of how a company is performing across the various service areas, and importantly highlight how the service areas are performing relative to one another. This enables the organisation to design and develop a structured approach to improving efficiency and business processes across the service areas, starting with those service areas performing most poorly. This is particularly advantageous when costs are an issue, and thus where it is important to effectively focus time, effort and resources into resources and new processes where they are most required. In addition it provides a means of benchmarking where an organisation is—relative to other organisations—and indeed in relation to previous performance of any given organisation. 
     In an exemplary embodiment the sets of service assessment evaluation data can correspond to management of appointing a task; management of dispatching a task; management of resources dispatched to a task; and task-completion management. Typically service assessment data are captured by customer facing groups within an organisation, since the services that are being assessed are provided to customers. 
     In one arrangement the integrated data collection platform is arranged to receive the one or each set of service assessment evaluation data via an HTTP communications channel, while in another the integrated data collection platform is arranged to receive the one or each set of service assessment evaluation data via e-mail. In a yet further arrangement the integrated data collection platform is arranged to receive the one or each set of service assessment evaluation data via file transfer. When received via e-mail or file transfer, the data are parsed, e.g. using Optical Character Recognition (OCR) techniques, so as to derive the one or each set of service assessment evaluation data. 
     When received via an HTTP communications channel, the service provider can first be provided with a URL corresponding to a server arranged to serve said set of service assessment evaluation questions, and the service provider, or service reviewer, can similarly input responses to the questions via the HTTP communications channel. 
     In a yet further arrangement the method comprises sending to the one or each service provider a software component comprising a set of executable instructions arranged to invoke the integrated data collection platform. The software component can be accompanied by the one or more sets of service assessment evaluation questions, and the software component is configured to receive responses to the questions and present the set of quantified performance measures in an integrated graphical display area on a terminal local to said service provider. For example, the software component and questions can be embodied within an Excel™ file comprising macros embedded therein, or as a Java™ application configured with the requisite functionality. 
     Conveniently, the method comprises creating a display area comprising a plurality of portions, each portion corresponding to a different set of service assessment evaluation data. Each of the portions comprises a plurality of regions, and each region corresponds to a member of the corresponding set of service assessment evaluation data; for each said set of service assessment evaluation data, points indicative of the quantified performance measures are inserted in a said region corresponding to respective members of the set. In this way the set of quantified performance measures can be presented in an integrated graphical display area and thereby enable relative performance between sets of service assessment evaluation data to be derived. 
     In one arrangement the integrated service delivery platform manipulates the one or each set of service assessment evaluation data in accordance with one or more predetermined functions so as to generate a weighted or normalised set of service assessment data. Preferably a given set of service assessment data are normalised with respect to other members of the set and indeed the members of a given set of service assessment data can be normalised with respect to members of at least one other set of service assessment data. In another arrangement the assessment data can be weighted on the basis of one or more factors corresponding to the services provided. 
     In a particularly advantageous embodiment each portion comprises a segment of a two-dimensional entity in the form of a circle, such that each portion comprises a segment of the circle. 
     Other aspects of the invention comprise a distributed system arranged to perform the method described above, while other aspects comprise a set of software components comprising a set of instructions adapted to perform the method steps described above when executed over such a distributed system. 
     Further features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention, given by way of example only, which is made with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As described above, embodiments of the invention are concerned with an integrated service assessment evaluation method and tool. The nature the evaluation and commensurate functionality of the tool will be described in detail below, but first a description of the infrastructure needed to support some embodiments of the invention will be presented with reference to  FIG. 1 , which shows an example of a distributed information system  1 . 
       FIG. 1  shows several service reviewer systems A . . . E, each of which can interact with an assessment tool server S 1  in order to gain a quantitative measure of the levels of service delivered by various operating arms of their organisation, or indeed of third parties contracted to provide a particular service. In the exemplary embodiments described herein, the organisation is a provider of services, specifically a provider that interacts with a customer in order to place an order for a task to be completed (appointment management); to schedule the allocation of resources to perform the task (work management); to track progress of the resources in attending to and completing the task (asset, or worker management); and to enter into a dialogue with the customer once the task has been completed (delivery management). The service reviewer systems  6   a  . . .  6   e  can be software applications running on a fixed or mobile terminal, and communicating with the assessment tool server S 1  via e-mail, HTTP or other transport protocols, and involve sending data via fixed and/or wireless networks; an exemplary arrangement of such networks including the Internet  12 , and a mobile network  10  is shown in  FIG. 1 . Further details of exemplary network arrangements are provided at the end of the specification. 
     There can be one assessment tool server S 1  serving a plurality of organisations, as shown in  FIG. 1 , or there can be one assessment tool server for each organisation. Further, whilst shown as single units in  FIG. 1 , it will be appreciated that the assessment tool server S 1  and database DB 1  can comprise a plurality of units distributed in the Internet  12 . 
     In either configuration, the one or each provider S 1  stores data identifying the organisation, in a storage system DB 1 , together with a list of parameters characterising each of the stages described above. For example, and as shown in  FIG. 2 , there might be sets P 1 , P 2 , P 3 , P 4  characterising each of appointment management, work management, asset management and delivery management, some or all of which might be measured by, and of interest to, the organisation. An exemplary, and non-limiting, list of the parameters making up the sets is shown in Tables 1-4 below:

     Any given service reviewer (which is to say the software running on a terminal  6   a  . . .  6   e  associated with a respective organisation) can register with the assessment tool server S 1  so as to define the sets of parameters that are of interest to their organisation. Alternatively the assessment tool server S 1  can profile the organisation according to a default set of parameters. Either way, once the service reviewer has registered with the assessment tool server S 1 , the service reviewer can thereafter request assessment of their organisation using a tool according to embodiments of the invention. 
     Turning now to  FIG. 3 , an arrangement of the assessment tool server S 1  will now be described. The assessment tool server S 1  is preferably embodied to communicate with a requesting terminal  6   a  . . .  6   e  associated with a service reviewer as a web server; the assessment tool server S 1  comprises standard operating system, storage, processor, input/output interfaces, together with includes various bespoke software components  301 ,  303 ,  305 . These latter software components are arranged, respectively, to receive a registration request for the assessment service, and indeed updates to a given account (registration software component  301 ), to query the database DB 1  on the basis of the identity of the requesting service reviewer in order to identify parameters of interest to the querying service reviewer (database querying software component  303 ), and to configure a review tool on the basis of the identified parameters of interest (review tool configuration software component  305 ). In addition, the review tool configuration software component  305  is arranged to send data to, and receive data from, the terminal  6   a  . . .  6   e  associated with the service reviewer to enable generation of the review tool. 
     Turning to  FIG. 4 , the steps performed by the assessment tool server S 1  when interacting with a service reviewer in a first embodiment will now be described. In a first step (S 401 ), the assessment tool server S 1  receives a request for a review tool from one of the terminals  6   a  . . .  6   e.  This request can be transmitted as an electronic (e-mail) message, as an SMS (Short Message Service) message, or as an application-specific message. In the event that the request is received as an e-mail or SMS message, the body of the message is formatted according to a pre-specified definition, which, for example, can be notified to the terminal  6   a  . . .  6   e  by the registration software component  301  when the service reviewer registers with the assessment tool server S 1 . In the event that the request is embodied as an application-specific message, this will have been transmitted by a bespoke application running on the terminal  6   a  . . .  6   e,  which may, for example, have been configured on the terminal  6   a  . . .  6   e  under control of the registration software component  301  as part of the registration process. 
     Once the request has been received by the assessment tool server S 1 , it is passed to the database querying software component  303 , which validates the request with recourse to organisation records stored in the database DB 1  (step S 403 ). Assuming the request to be successfully validated, the database querying software tool sends a message to the terminal  6   a  . . .  6   e  of the requesting service reviewer, the message requesting details of the preferred medium for activating the review tool (step s 405 ). The message can be sent as an e-mail message, an SMS message, or as an application-specific message, in the manner described above. Alternatively, and in the event that the service reviewer specified the preferred medium as part of the registration process, the database querying software component  301  retrieves details of same from the record corresponding to the querying service reviewer. 
     Having received the preferred medium for activating the review tool at step S 405 , the database querying software component  301  retrieves all of the sets of parameters registered as of interest to the service reviewer (again, on the basis of the identity of the associated organisation), and passes these, together with details of the preferred medium, to the review tool configuration software component  305 . At decision point S 407  the review tool configuration software component  305  identifies whether the requesting service reviewer has requested for the tool to be executed locally (that is to say, on the terminal  6   a  . . .  6   e ) or remotely (that is to say, on the assessment tool server S 1 ). As shown in  FIG. 4 , the method splits into two paths dependent on the output of the decision point. Considering firstly a service reviewer that has specified local processing of the review tool, the review tool configuration software component  305  generates an application that can be delivered to the terminal  6   a  . . .  6   e  for processing thereon (step s 409 ). 
     In one arrangement this application is embodied as an excel file, which is to say an excel file containing fields that require manual input and macros that are linked to the fields so as to generate service assessment output. The fields in the excel file comprise questions that correspond directly to the parameters retrieved from the database DB 1  when validating the request at step S 403 , and thus present service data that are meaningful to this service reviewer. Once the application has been configured, it is transmitted to the requesting terminal  6   a  . . .  6   e  (step S 411 ). 
     An example of these fields for a service reviewer corresponding to organisation A is shown in  FIGS. 5   a  . . .  5   d,  from which it can be seen that the fields include questions corresponding to the parameters of each set P 1  . . . P 4 , as listed in Tables 1-4 above. Moreover the fields include a column  501  to receive input from the user in relation to each of the questions. The input can be specified in the form of a quantifiable measure of performance, and in a preferred arrangement the input comprises a number within a predetermined range such as 1-5, as indicated in  FIGS. 5   a - 5   d.  The excel file additionally comprises macros which operate on the data entered into columns  501   a  . . .  501   d  and that are configured to generate an integrated graphical display of the service data, which is to say the quantified data entered by the user. An example of the graphical display area into which the generated data is output is shown in  FIG. 6 , while  FIG. 7  shows the display area after a user has input respective performance values into the respective columns  501   a  . . .  501   d  with the input data output therein. In this arrangement, the display area is a circle comprising four segments, each corresponding to a service area and each of which comprises as many sub-sectors as there are parameters; furthermore each segment has a plurality of radial markings, each corresponding to a score that can be entered into columns  501   a - 501   d.    
       FIG. 7  demonstrates the advantages provided by a review tool according to an embodiment of the invention: the tool provides an integrated view of how a company is performing across the various service areas, and importantly highlights how the service areas are performing relative to one another. In the example shown, it is clear that the service area of work management performs relatively poorly compared to the other service areas. This enables the organisation to design and develop a structured approach to improving efficiency and business processes across the service areas, starting with those service areas performing most poorly. This is particularly advantageous when costs are an issue, and thus where it is important to effectively focus time, effort and resources into resources and new processes where they are most required. In addition it provides a means of benchmarking where an organisation is—relative to other organisations—and indeed in relation to previous performance of any given organisation. 
     As an alternative to configuring the review tool as an excel file, the tool can be configured as a Java™ application such as an applet, which is downloaded to the requesting terminal  6   a  . . .  6   e  suitable configured with a Java Virtual Machine (JVM) and thus adapted to run the applet when received thereon. 
     Turning back to  FIG. 4 , the steps performed by the review tool configuration software component  305  when the requesting terminal  6   a  . . .  6   e  indicates that the tool should be run remotely will now be described. In this embodiment, the assessment tool server S 1  functions as a web application in addition to a web server. In one arrangement the terminal  6   a  . . .  6   e  is configured with a web browser, which is configured to run various Java Script code and thereby communicate with the web server of the server S 1  so as to retrieve object data and transmit data requests. The web server is configured with a bespoke Servlet™ which communicates with the scripts running within the terminal browser using HTML and XML, preferably using Ajax™. 
     Accordingly, at step S 801  the review tool configuration software component  305  sends an instruction to a browser running on the terminal  6   a  . . .  6   e,  the instruction containing a URL that directs the browser to the web server, together with a cookie (or similar) which can subsequently identify the requesting terminal  6   a  . . .  6   e  to the assessment tool server S 1 . Having received the relevant HTTP request, the web server running thereon invokes the associated web application and presents the requesting terminal  6   a  . . .  6   e  with a form, having content similar to that shown in  FIGS. 5   a - 5   d,  and instructing the user to input quantitative measures of performance in relation to each of the sets of parameters retrieved by the database querying software component  303  (step S 803 ). At step S 805  the review tool configuration software component  305  processes the values input by the user of the terminal  6   a  . . .  6   e —e.g. the values shown entered into the tables in  FIGS. 5   a - 5   d —and generates output that can be displayed in a display area within the browser of the terminal  6   a  . . .  6   e  in the manner shown in  FIGS. 6 and 7 . 
     In a further embodiment still, a set of forms could be sent to the user of the requesting terminal  6   a  . . .  6   e  as an attachment to an e-mail message, each set comprising the questions set out in  FIGS. 5   a - 5   d.  Upon receipt of a completed form (e.g. by return e-mail), the review tool configuration software component  305  could parse and process the values input by the user of the terminal  6   a  . . .  6   e,  then generate output and store a file depicting, graphically, the generated output. This graphical output could similarly be e-mailed to the user of the terminal  6   a  . . .  6   e  as a file attachment, or alternatively a URL could be e-mailed to the user of the terminal  6   a  . . .  6   e,  directing the browser running on the terminal  6   a  . . .  6   e  to the web server where the file has been stored, for viewing via the browser. 
     In a yet further embodiment, the set of forms could be posted via regular mail to an office of a requesting service reviewer (whose postal details would be stored in DB 1 ); upon receipt by an administrative office associated with the assessment tool, the completed forms could be scanned in and analysed using Optical Character Recognition (OCR) tools so as to derive the input manually entered by the service reviewer. Output could be generated in the manner described above, and the graphical output posted to the organisation associated with the service reviewer. 
     The above embodiments describe a scenario in which there are four sets of parameters, and in which data input in relation to each set of parameters is displayed in a segment, or sector, of a circle. Whilst the sectors are shown evenly distributed within the circle, they could alternatively be weighted so as to generate an uneven distribution, for example, with a relatively larger segment being assigned to whichever set of parameters the organisation scores most poorly so as to enable the reviewer to analyse the poorly performing areas in more detail. The relative sizes of the segments could be determined on the basis of how the sum of the parameters within a given set compare to that of the other sets. For example, in the example shown in  FIG. 6 , the combined score of the set of parameters corresponding to appointment management as shown in  FIG. 5   a  is  58 ; that corresponding to work management as shown in  FIG. 5   b  is  23 ; that corresponding to asset management as shown in  FIG. 5   c  is  63 ; and that corresponding to delivery management as shown in  FIG. 5   d  is  52 . Thus if the sectors were to be inversely scaled according to relative performance, appointment management would be assigned 73.5° of the circle, work management would be assigned 137.7° of the circle, asset management would be assigned 64.3° of the circle and delivery management would be assigned 84.5°, and in this way ensure that visual focus is on the most poorly performing sector. Full details of calculations performed when identifying the scaling are as follows:
     Overall score: 196 (58+23+63+52); four equal quadrants would score 49 each; thus   

     appointment management scored higher by 9 
     work management scored lower by 26 
     asset management scored higher by 14 and 
     delivery management scored higher by 3
     Thus sector calculations:   

       appointment management: 90°×(1−(9/49))=73.5° 
       work management: 90°×(1−(−26/49))=137.7° 
       asset management: 90°×(1−(14/49))=64.3° 
       delivery management: 90°×(1−(3/49))=84.5°     Such a scaling algorithm could be provided as an integrated part of the excel macros, which operate on the input values in the manner described above.   
     Whilst the above description exemplifies the invention by means of four sets of parameters, it is to be appreciated that fewer, or indeed more, than four could be used. Indeed, as shown in  FIG. 2 , it may be that any given organisation only specifies a subset of available sets of parameters as being relevant for evaluating the performance of their organisation (or indeed third parties providing service thereto). It will also be appreciated that the number of segments populated graphically by the review tool configuration software component  305  will relate directly to the number of sets of parameters. 
     In addition, whilst in the above exemplary embodiment a circle is used to depict the entered performance values, it will be appreciated that other shapes, indeed including three dimensional shapes, may be used to display the output, and that the shape may comprise a part-circle such as a hemisphere 
     In the above embodiments, it is assumed that an organisation has only one business unit that will be assessed in relation to the service areas described above, or at least that the business units making up the organisation are sufficiently harmonised that a single value can accurately reflect service effectiveness across all units of the organisation. For such organisations it is of course a straightforward matter to assign a single value for a given parameter of the respective service areas; however, other organizations may operate quite independently of one other, with the result that any measure of performance may vary considerably for any given parameter of a given service area. For example, telecommunications companies typically offer Plain Old Telephone Service (POTS), Digital Subscriber Line (DSL), Internet services (ISP) etc., among other services, and each of these services is managed and operated by a different team. Accordingly, whilst there is a significant degree of overlap between the services provided and indeed the equipment utilised to provide the services, since the delivery of these services is managed on a per business unit basis, the delivery of the services may vary considerably between business units. Thus embodiments of the invention provide a means for assessing service effectiveness per business unit in order to enable the organization to establish effectiveness and failing areas per business unit. 
     More specifically, the review tool configuration software component  305  is arranged to process and generate individual display areas for each business unit, each being of the form shown in  FIG. 6  (e.g. one circle for POTS services, one for DSL services etc.). The display areas can collectively be presented to the reviewer as an n-dimensional set of circles, together with a set of graphical configuration tools which enable selection of individual ones of the circles, thereby enabling the reviewer to add or remove individual display areas. In addition the review tool configuration software component  305  can generate average and standard deviation values for each parameter of a given set of service areas, thereby enabling the reviewer to identify relative performance between business units for any given aspect of the services provided by the service as a whole. 
     Referring now to  FIGS. 9   a - 9   c,  a further embodiment of the invention, which involves assessment of environmental aspects of how the mobile worker is managed by the organisation, will now be described. These environmental areas comprise managing the mobile worker&#39;s work ( FIG. 9   a ); managing the mobile worker ( FIG. 9   b ); and managing the mobile worker&#39;s assets ( FIG. 9   c ). In this embodiment the “score” entered by a given reviewer is a binary input of the form “Yes/No”, individual ones of which, for each environmental area, can be combined so as to give an overall score either for individual environmental areas, or for the combined environmental areas. In the event that the scores are combined per individual micro-service area, a graphical representation thereof can be generated in the manner described above, so as to enable identification of the relative inexperience of a given aspect of the mobile worker&#39;s management. This in turn enables a given reviewer to identify particular aspects of the mobile worker&#39;s management that should be improved so as to harmonise, environmentally, the mobile worker across the various areas of the organisation. 
     In the event that the scores from individual environmental areas are combined, an overall score can be generated. Accordingly, the application configured at step S 409  (or accessed at step S 803 ) can comprise a further interface and corresponding executable instructions, which capture input from the user in relation to the individual environmental areas, and generate a measure of fuel usage. An example of output so generated is shown in  FIG. 10 , for the example set of inputs entered by a given service reviewer shown in columns  901   a  and  901   b  of  FIGS. 9   a - 9   c.    
     Additional Details and Modifications 
     As described above, the service reviewer software can run on mobile terminals or fixed terminals. In relation to mobile devices, the terminals can be mobile telephones or PDAs, lap top computers and the like, and the mobile network  10  can comprise a licensed network portion (such as is provided by cellular networks using e.g. Global System for Mobile Communications (GSM) technology, Wideband Code Division Multiplex Access (WCDMA); Code Division Multiplex Access (CDMA), WiMax) and/or unlicensed network portions (such as is provided by Wireless LANs and Bluetooth technologies). The gateway GW  8  facilitates communication between the mobile network  10  and the Internet  12  and can be configured as a GPRS support node (GGSN) forming part of the mobile network  10 . 
     Whilst  FIGS. 5   a  . . .  5   d  show examples of metrics and threshold trigger points that can be utilised by a tool configured according to an embodiment of the invention, it will be appreciated that such metrics are likely to be sector and industry specific. Thus a more specialised version may be appropriate for industries/verticals with measurement criteria that relate more closely to that vertical. 
     Furthermore, it will be appreciated that the service areas listed above, namely appointment management, work management, asset management, and delivery management are exemplary and that both the number of sets of parameters and indeed the parameters in the sets can change. In relation to the embodiment described above, it is to be noted that the appointment management service area could usefully be generalised to cover the area of commitment management where not all work is ‘appointed’ but completion commitments are still being made. This applies particularly in the network ‘build’ &amp; proactive network maintenance contexts where the work is not directly customer-facing. 
     The above embodiments are to be understood as illustrative examples of the invention. It is to be understood that any feature described in relation to any one embodiment may be used alone, or in combination with other features described, and may also be used in combination with one or more features of any other of the embodiments, or any combination of any other of the embodiments. Furthermore, equivalents and modifications not described above may also be employed without departing from the scope of the invention, which is defined in the accompanying claims.
