Description:
This is a Continuation-in-Part application based on Application No. 08/955,569 filed Oct. 22, 1997. 
     The present invention relates to the field of collaborative software systems. More specifically, the invention relates to a system and method for providing intranet-based groupware functionality. 
    
    
     BACKGROUND OF THE INVENTION 
     Recently, the need for collaborative computing environments has been receiving increasing attention. People are finding that it is more and more important to share information and work together to meet common goals. With increasing specialization in the marketplace, there is frequent need to work together with people from different offices, different organizations and even different countries to satisfy the requirements of a particular project or goal. Managing collaborative initiatives of this type is not a simple matter. 
     Electronic network based, project management server systems are known. For example, U.S. Pat. No. 5,548,506 [Srinivasan] discloses an automated, electronic network based, project management server system for managing multiple work groups. The system comprises a core piece of software which runs on a host server computer system and interacts with a messaging system such as E-mail or facsimile. The system compiles multi-project plans into a multi-project database and tracks the ownership of projects, tasks and resources within the plans. The system automatically checks all resource requests and if resource availability limits are exceeded then resources are allocated on projects based on priorities and project plans are changed accordingly. The system is also programmed to send out reminders and follow-ups and the databases are continuously updated on status changes reported by work group members. 
     One of the disadvantages of known electronic network-based, collaborative server systems is that they depend on Information Technology specialists or a system administrator to administer control of the system, i.e., if a user wishes to add functionality to a system, they must have access to the program itself. Further, many collaborative systems require each user to have specialized software installed on their computer. 
     It is an object of the present invention to obviate and mitigate at least one of the disadvantages of the prior art.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A system to provide a team of users with intranet-based groupware functionality in accordance with an embodiment of the present invention is shown schematically in FIG.  1 . 
     The system generally comprises at least one server computer as an intranet connected server  10  which supports a TCP/LP protocol and which has input and access capabilities via two-way communication lines, such as communication lines  15  and  20 . The computer is configured as a web server. Server  10  has a unique resource locator (URL) address and comprises a means to create a dedicated intranet site  25  (e.g. Site# 4 ) on the server in response to an initiate request received from a primary user  30 . Dedicated site  25  has a unique address which identifies it with the primary user  30  (e.g., # 4 ) within server  10 . Server  10  further comprises a means to send information, including its URL address and the unique address of the dedicated site, to at least one secondary user  40 , nominated by the primary user  30 . 
     Both primary user  30  and secondary user  40  can communicate with server  10  by means of an HTML compliant client supporting a graphical user interface and internet browser, such as Netscape Navigator or Microsoft Explorer, i.e., there is no requirement that either primary user  30  or secondary user  40  have access to specialized software applications in order to utilize the system of the present invention. Information on the site  25  is credited as a hypertext document and is thus displayed as a web page on the GVI of the user&#39;s web browser, with a link to this hypertext document. 
     Once connected to dedicated site  25  created on server  10 , primary user  30  and secondary user  40  both have access to at least some of the information stored at the site, the ability to access and process at least some of the information and the ability to input and store processed and/or new information. All the specialized software which provides the functional requirements to give primary user  30  and secondary user  40  these abilities is provided by server  10  via dedicated site  25 . Once again, primary user  30  and secondary user  40  do not require any specialized software applications other than a standard internet browser. 
     Server  10  may be provided a number of general sites (e.g., Sites # 1 , # 2 , # 3 ) which are automatically accessible to primary user  30  and secondary user  40 ; other sites (e.g., Site # 6 ) which are accessible to only one of the users; and some sites (e.g., Site # 7 ) which can only be accessed by a system administrator (not shown). The nature and purpose of these different sites will be describe in more detail below. 
     It will be apparent that although the system of the present invention is primarily intranet-based, the nature of communication lines, such as line  15  between server  10  and primary user  30 , is not particularly limited. An intranet is simply defined by its security parameters for the connected users. Suitable intranet-adaptable communication lines include dedicated liens, public telephone networks, private telephone networks, satellite links, Ethernet links, etc. These communication lines are already in place if primary user  30  and secondary user  40  have existing intranet access. 
     It is envisioned that server  10  may be connected to the internet as well as an intranet. A suitable firewall (not shown) may be provided between the intranet and external or intranet users. As will also be apparent in this embodiment, the geographic locations of primary user  30 , secondary user  40  and server  10  are only limited by internet accessibility, i.e., all three need not be in the same city, county or even continent. 
     The dedicated site created in response to the initiate request can be thought of as being a private office suite within the semi-public intranet. 
     The private office suite may be created on the server for a period of time desired by the primary user, after which time the private suite can be erased to free-up system resources. The private office suite comes complete with all the application software required to permit group activity within the office. The primary user can construct a private office suite to include the specific applications desired. Thus, an advantage of the present system is that the user is provided with a customizable, secure office suite in which the user and his/her team members can access applications software without the need for each team member to have individual copies of each applications software. 
     The system of the present invention is “end-user friendly”, i.e., neither primary user  30  nor secondary user  40  need specialist computer knowledge to make use of the system. There is no requirement for the primary user to have an in-house Information Technology specialist. 
     The system of the present invention is further understood when described by its mode of operation and with reference to FIG.  2 . 
     In order to create a private office suite, a primary user uses his/her web browser  110  to contact the intranet connected server. The server confirms the identity  120  of the primary user and directs the primary user to the system homepage  130 . From the system homepage, the primary user can access his/her personal workspace  140 . 
     Among other options which will be discussed below, the primary user has the option to enter an existing workgroup with a pre-defined dedicated site or to create a new workgroup with a new, unique dedicated site ( 150 ). 
     If the primary user wishes to enter an existing workgroup the server permits access to the pre-defined site ( 160 ). 
     If the primary user wishes to create a new workgroup, he/she is provided with a workgroup creation template ( 170 ) which permits the primary user to define parameters of the workgroup, such as the name of the workgroup and the site to be created, the scope of the project being undertaken, the number of team members, etc. 
     During completion of the template, the primary user is prompted to identify the number and contact addresses of the group members, the types of user applications which are to be utilized during the project and to provide a name for the dedicated site to be created. 
     Once this template has been completed, the server creates a dedicated site ( 180 ) having the name chosen by primary user. The administration sub-system checks to see whether all the prospective group members identified by the primary user are listed on the existing intranet-user database ( 190 ). If a prospective group member is an existing intranet user, the server then sends details of the newly created dedicated site to that member of the group (secondary user) ( 200 ). In a presently preferred embodiment, the server automatically creates a link between each secondary user&#39;s personal workspace and the newly created dedicated site. Alternatively, the details of the web-site may be sent in the form of an E-mail message which provides each secondary user with the address of the dedicated site, an invitation to join the workgroup and, if applicable, the password required for gaining access to the site (see later). 
     If a prospective group member is not an existing intranet user, the administration sub-system determines whether the primary user has the authority to add external users ( 210 ). If the primary user does have authority to add external users, the server creates a personal workspace for that user ( 220 ) and notifies the external user of the existence of the workgroup ( 230 ). Preferably, the notification is done by means of E-mail, although other means, such as facsimile or pager, may also be used. Once authorized, an external user can contact the server via the internet and the external user has access to the same operational functionality as an intranet-connected user. 
     If the primary user does not have authority to add external users, a request is sent to a designated system administrator who makes the determination whether the external user can be added to the new workgroup ( 240 ). If approval is given, the system creates a personal workspace for the external user as before ( 220 ), if the addition of the external user is not approved, the primary user (requestor) is advised ( 250 ). 
     Once the approved secondary users have been notified of the existence of the dedicated site, the workgroup remains operational until all workgroup activities have been completed ( 260 ). When the primary user decides that there is no longer a requirement for the workgroup, the workgroup is closed ( 270 ) and the dedicated site may be deleted from the server. Prior to closure and deletion of the dedicated site, primary user may be given the option of downloading and storing all the data from the site for archive purposes. 
     During the creation of a dedicated site, secondary user nomination, workgroup activity, closure of the workgroup and eventual deletion of the site, all the administrative details of the workgroup activity are automatically fed into the administrative sub-system for processing. The administration sub-system controls all the day to day management of the system. It contains all the code and script required for workgroup size monitoring and database size monitoring. Further, the administration sub-system is responsible for monitoring server traffic and hit counts and the control of the offering of additional subscriber applications. 
     Security is an important feature of most business activity and the system of the present invention provides many levels of security which can be selected by the primary user and/or system administrator to suit his/her individual needs. For example, a basic form of security is to provide the dedicated site created with a password which must be entered by both the primary user and the secondary users to gain access to the workgroup. This password may be the same for the primary user and all the secondary users or every secondary user may be provided with a unique password. Providing each secondary user with a unique password also permits primary user to set up different levels of information which can be accessed within the workgroup by each secondary user, i.e., the workgroup can be created on a “need to know” basis. Examples of other security features include the ability of the primary user to decide: who has the authority to add new secondary users to and/or delete existing secondary users from the group after its creation; who has access to the administrative records of the workgroup; and when and if passwords and/or security levels are to be changed. 
     As will be apparent, there are many different types of workgroup activities which can be performed on a system in accordance with the present invention. In fact, it is envisioned that the present system could be adapted to perform many of the tasks of conventional LAN- or WAN-based group collaboration systems. Preferred workgroup activity applications of the present system include bulletin board, chat room, calendar, contact database, change control, event planner, group discussion, issue management, project collaboration, presentation library, decision survey in a box, NGS proposal development, document manager, and You Own Custom Application. 
     A bulletin board is a common place for team members to post anything that might be of interest to the team. Discussion, file attachments, and broadcast main are available. Additionally, a number of views may be utilized to gain access to the information, including by date, by author, by type, etc. 
     A chat room is a real-time chat function for teams to schedule discussions on the fly. 
     A calendar is a central calendar dedicated to the team, where individuals may add entries to keep track of milestones, issues and events. It is presented in a dynamic view, i.e. 2day, one week, two weeks or one month. 
     A contact database is an application that allows groups to track specific contracts in a central place. The views allow sorting by name, company type, etc. 
     A change control is a workflow application that allows teams to request and manage project changes. 
     An event planner is an application that is targeted at managing the deliverables for an upcoming event. Team members can assign tasks and milestones, broadcast mail to the stakeholders, and view a calendar in a number of formats. 
     The group discussion is a complete collaborative application that offers groups a central meeting place for the exchange of ideas. 
     Issue management is a workflow application that allows project teams to report issues, notify the owners, and track the resolution. 
     Project collaboration is a complete project management tool that provides managers and team members a Web sit environment for creating, implementing and managing projects. Involv Project Collaboration also imports and exports Microsoft Project Plans. 
     Presentation Library is an application similar to document management but specific to storing presentation files for sales and marketing use. File attachments, descriptions and a variety of views make accessing information easier. 
     The Decision Survey in a Box is a survey application created by Emerging Technology Solutions for Involv Intranet, Decision Survey allows for instant creation of surveys for publishing and gathering data from groups on the Intranet or extranet. 
     NGS Proposal Development is a workflow application created by Nexgen Solutions for Involv Intranet. This application allows all stakeholders in the proposal development process to come together with content quickly and effectively. 
     Document Manager is a central depository for posting and managing files and documents of all types. Check in/Check out and decision history makes this a powerful team tool. 
     Your Own Custom Application is a Domino application that can be offered through the Involv Intranet Desktop for self-service. 
     An embodiment of the system of the present invention is shown in FIGS. 3 a - 3   e . All the display screens of the system exemplified in FIGS. 3 a - 3   e  have the appearance of a personal organiser, with an index “page” ( 300 ) on the left-hand side and a details “page” ( 310 ) on the right-hand side. The index page is tabbed ( 320   a - 320   d ) for convenient organisation and ease of use. As will be apparent, the style of screen display is not limited to this personal organiser style of display. Screen displays can be customized to a user&#39;s preference. 
     FIG. 3 a  shows a system homepage ( 130 ) as would be seen by a user upon accessing the system. The system homepage may be used to provide links to general access features such as new, library resources, phone directories, office procedure manuals, etc. From the system homepage, a user can also tab to their own personal workspace ( 320   b ). 
     FIG. 3 b  shows a typical personal workspace as seen by the owner. The index page provides links to the dedicated sites to which the owner has access and also to some generic applications such a personal messaging, chat groups and E-mail. 
     FIG. 3 c  shows a typical personal workspace as seen by a visitor. This level of a personal workspace may be accessed to any intranet user or authorized external user via the users directory (Tab  320   c ). In this instance, index page  300  provides links to other users, not to the person&#39;s personal dedicated sites. The details page provides information on, for example, contacting the users, the users specialty and the users present availability. 
     FIG. 3 d  shows an application menu (Tab  320   d ) which can be utilized by a user to create dedicated sites and add users to a workgroup. Different styles of sites can be created, depending on the function of the site, e.g., Project Collaboration, Event Planning, Document Managing, etc. The details page can be used to give a user an overview of each type of workgroup and provide a link to a template for creating the group. If a user creates workgroup having a dedicated site, a link to that site is automatically created on the index page  300  of a nominated secondary user&#39;s personal workspace (FIG. 3 b ). 
     FIG. 3 e  shows an administration screen which provides a system administrator with access to all aspects of the system.
