Vision - Problem Statement The problem of Complexity in meeting organizing, not efficient process Affects Any organization or an individual who needs to organize meetings. the impact of which is 1. 2. 3. 4. 5. 6. 7. 8. a successful solution would be ã All participants are not easily reached. Date and location conflicts and difficult to resolve. Re-scheduling and/or cancellations require additional effort. Scheduling of large meetings is very difficult and time consuming and may require numerous calls to every person. Delay and ultimately improper resource utilization Entities spend a significant amount of time and resources organizing meetings Too many negotiations The effects of all the factors above are amplified as the number of participants’ increases. An accessible, cost-effective meeting scheduler that can be used to initiate and schedule meetings. It will contact and collect participant availability data. Aid the user to decide on the meeting arrangement by ranking alternatives based user configurable criteria The product would also address issues related to conflict in dates and provide an efficient method to solve any such problems It will allow for re-planning and support interactions for negotiation activities.

Vision -Stakeholder's summary Design Team Implements and produce actual software products. Testing team Maintenance team ã Generates software artifacts according to the design. Follows the project process. Ensures that the system is works correctly and fulfills the design specifications. Generates test plans and procedures. Documents and report bugs encountered. Follows the project process. Responsible for resolving problems with software after released. SAP AG 2007, SAP CSUN 2007 Conference Presentation / 6 Generates software patches of fixed to resolve problems (nonrelated with installation of configuration) with system between releases. Generates software patch installation procedures. Documents changes and updates design documents to reflect changes. Follows the project process.

Vision -User summary Organization or Employee End user Initiate meeting, re-schedule meetings send requests, respond to meetings invites, view meetings, send/receive meeting confirmations, specify contact information, assign representative, negotiate/solve conflicts , Provide date ranges (exclusion sets and preference sets. ), notify participants, confirm attendance, and view meeting’s agenda. Self Administration End user In addition to the regular User responsibilities. Manages user’s accounts, locations and equipment. Installs, repairs, starts and stops system.

Requirement Changes 1. Some meetings are organized and scheduled at the same time, as a chunk, where partial attendance can be allowed. Solution 1: Important and active participants shall be allowed to attend only part of the meeting by choosing the attend partial option along with acceptance of a meeting invitation. Solution 2: Do not allow partial attendance at all Final Resolution: Option 1 was chosen as it provides more flexibility for the important and active users to attend more than one meeting in case their presence is expected in more than one meetings. While resolving conflicts, meeting schedule of active/important participants shall not show as conflict for partial attendance meeting. Option 2 imposes a more restricted rule hence is not considered as an option. 2. Meeting locations should be convenient, and information about meetings should be secure. Final Resolution: Location convenience is already addressed as important participants are allowed to specify location. Only important and active participants location preferences are considered while resolving location conflicts. Secure means that only authorized users are allowed to use the system. Users shall be able to register in the system, but permission will be provided only after receiving the email confirmation from the admin. Users shall be able to view the meetings that are either initiated by them or to which they are invited, they shall not be able to view other users meeting details. ã SAP AG 2007, SAP CSUN 2007 Conference Presentation / 17

Requirement Changes 3. For helping with conflict resolution and negotiation support, video conferencing would be available on the system and each video conferencing session should be recorded analyzed for the purpose of the meeting. Solution 1: The system shall provideo conferencing option between 2 geographical locations. Solution 2: Do not allow video conferencing option Final Resolution: Option 1 is chosen as it provides the ability to schedule and monitor virtual meetings without having restrictions on the geographical location of the participants. 4. Some stakeholder has also requested that your meeting system provide such features that can be found, for example, in Microsoft Office Outlook. Solution 1 : Some of the features provided by outlook 1. Cancel meeting and notify users by email 2. Provision to decline meetings 3. Respond to meeting with preferences 4. Send meeting Reminders and reminders to respond to meeting requests via email Solution 2: Requirement is ignored Final Resolution: Option 1 is selected as it provides more user friendly features offered by other meeting scheduler products like Outlook ã SAP AG 2007, SAP CSUN 2007 Conference Presentation / 18
