Goal The primary goal of this project is to provide a complete requirements description for the Distributed Meeting Scheduler(DMS) for HighImpactSoft, Inc. HighImpactSoft has provided an initial description of DMS and it is our task to refine, enhance, and develop this initial description into a complete requirements document.
Definitions • Meeting: scheduled gathering of two or more people. Meeting parameters include: date, time, initiator, participants, place (physical or virtual) • Meeting initiator: A person who initiates a meeting, notifies possible participants, determines potential meeting dates/times/places; may also be a participant. • Potential attendee: A person who provides a set of dates when they may or may not be able to attend a proposed meeting. • Participant: A person who attends a meeting. • Exclusion set: set of dates provided by potential attendees when they cannot attend a proposed meeting. • Preference set: set of dates provided by potential attendees when they can attend a proposed meeting. • Active participant- A meeting attendee who will do a presentation • Important participant: A meeting attendee who must be in the meeting • Regular participant: A meeting attendee who is not an active or important participant • OO: Object-Oriented • GUI: Graphical User Interface • SE: Systems Engineering • SRS: Software Requirements Specification
The proposal should be made as early as possible. Issue: The term as early as possible needs to be defined. How much time is as early as possible? Option 1: The conflict must be resolved within one week or the meeting will be rescheduled. Option 2: The system automatically calculates a meeting date after a time specified by the initiator. Option 3: The system automatically calculates a meeting date within 30 minutes. Solution: option 1 and 2 (administrator gets help in resolving available times).
The proposal should be made as early as possible. • Issue: The term as early as possible needs to be defined. How much time is as early as possible? • Option 1: The conflict must be resolved within one week or the meeting will be rescheduled. • Option 2: The system automatically calculates a meeting date after a time specified by the initiator. • Option 3: The system automatically calculates a meeting date within 30 minutes. • Solution: option 1 and 2 (administrator gets help in resolving available times).
Location should belong to one of the locations preferred by as many important participants as possible • Issue: location availability and time preference can conflict and importance or precedence is an issue. • Option 1: Define exclusion/preference sets as most critical and thus fully taken into account first. Location preference by important participants taken into account only after all time sets taken into account. • Option 2: Create a point system defining the level of importance of meeting attendees. Let the program take into account the level of importance of attendee and define some algorithm that balances importance of an attendee and define some algorithm that balances importance versus location/exclusion/preference sets. • Solution: option 1 (due to limited time and resources of implementation)
In application Domain, meetings are typically arranged in the following manner. • Issue: Typically creates multiple ways to arrange a meeting. • Option: Remove typically and choose one method of making meetings. • Option 2: Describe all ways in which meeting will be made and incorporate them into program. • Solution: option 1 (option 1 reduces complexity of problem)
The exclusion and preference set should be contained in some interval prescribed by the meeting initiator (which will be referred to date range) • Issue: interval is incompletely described and identified. • Option 1: Time interval defined to start calendar date (12:00 am) – end calendar date (12:00am) • Option 2: Time interval defined to consist of start calendar date and start time – end calendar time and end time. • Solution: option 1 (reduces variables
The number of negotiations should be kept minimal, but a new round of negotiations may be required when no such room can be found. • Issue: The terms minimal and negotiations need to be defined. • Option 1: The term negotiation is an attempt between two or more important participants to reach a compromise on where a meeting should be held. • Option 2: When setting up a meeting, the initiator can set a maximum amount of negotiations. When the maximum number is reached, the initiator will choose the final location him/her self. • Option 3: The maximum number of negotiations is 10. When the maximum number is reached, the initiator will choose the final location him/her self. • Solution: Option 1 + Option 2
Meeting requests can be competing when they overlap in time or space. Concurrency must thus be managed. Problem: This requirement seems to make an allowance for an overlap in space. Option 1: Allow the same location to be requested by multiple initiators and resolve the conflict. Option 2: Reserve rooms based on a first-come-first-serve basis. Solution: 2 Reason: Reserving rooms based on a first-come-first-serve basis eliminates any overlap in meeting space and is easy to implement.
“The purpose of DMS is to support the organization of meetings – that is, to determine, for each meeting request, a meeting date and location so that most of the intended participants will effectively participate.” Problem: The meeting time is not specified. Option 1: Include time in addition to the meeting date. Option 2: Leave the requirement as is. Solution: 1 Reason: A meeting scheduler by its very name requires that not only the date a meeting convenes but the time at which it convenes should be specified
“to keep participants informed about schedules and their changes.” Problem: This statement doesn’t say how to keep participants informed. Option 1: Send emails to alert prospective attendees of schedule invitations, rescheduled times/dates, and cancellations. Option 2: Remind the meeting initiator to alert prospective attendees of schedule invitations, rescheduled times/dates, and cancellations. Solution: 1 Reason: Emailing prospective attendees of schedule invitations, rescheduled times/dates, and cancellations can be done automatically by the program, eliminating human error.
“it should ideally belong to as many preference sets as possible.” Problem: This leaves it open whether the program should automatically select a date that is in the largest set of intersecting preference sets or whether the date should be selected by the initiator. Option 1: The system automatically selects the meeting date. Option 2: The initiator selects the meeting date. Option 3: The system suggests the meeting date and asks for the initiator to either confirm the suggested date or select an alternate date. Solution 3: Option 3 allows is an ideal solution because it offers a high degree of control and flexibility. Having the initiator confirm the meeting date also provides an active reminder of the selected date.
“Meeting requests can be competing when they overlap in time or space. Concurrency must thus be managed.” • Problem: This requirement seems to make an allowance for an overlap in space. • Option 1: Allow the same location to be requested by multiple initiators and resolve the conflict. • Option 2: Reserve rooms based on a first-come-first-serve basis. • Solution: 2 • Reason: Reserving rooms based on a first-come-first-serve basis eliminates any overlap in meeting space and is easy to implement.
“The initiator could also ask, in a friendly manner, active participants to provide any special equipment requirements on the meeting location (e.g., overhead projector, workstation, network connection, telephone, etc.).” • Problem: Besides the ambiguity over “active” and “important” participants, the requirements are presented clearly regarding the equipment requirements. • Solution: Options for any special equipment requirements need to be included along with the meeting time, date, and location preference options.
ISSUE 1 [NFR – 1] Requirement - A meeting should be accurately monitored, especially when it is held in a virtual place. Here, nomadicity will then be important to consider; Description – The requirement here is incomplete& unsound. The word accurately is not defined and cannot be measured. It does not specify what the system should monitor and how should it be monitored exactly. Is it the proceedings of the meeting or the presence of participants or anything else? Option 1 -Attendees of the meeting are monitored. The presence of important and active participants is taken care of. Option 2 - The process of the meeting is taken care of. The attendees of every period of the meeting are taken care of. It can be achieved by someone (initiator can appoint one (secretary) of more participants) records the meeting note/log. Option 3 - The content discussed in the meeting shall be recorded by slides or audio files Option 4 -The behavior and interaction of attendees shall be monitored Solution -Option 1 + Option 2 + Option 3
1.12.2 ISSUE 2 [NFR – 2] • Requirement - Re-planning a meeting should be done dynamicallyand with much flexibility as possible. • Description – The requirement here is ambiguous& incomplete. As who will re-plan the meeting and when should a meeting be re-scheduled are not specified. The words dynamically and flexibility are not defined and hence cannot be quantified and measured. • Option 1 -Meeting initiator shall re-plan the meeting, when a meeting which has already been scheduled, however need to be re-scheduled for some reason. (With unlimited opportunities) • Option 2 -Active/important participants can change their preference or exclusion set (with limited opportunities) or withdraws the meeting • Option 3 - lower bound (defined at another requirement) affects at this point. After the lower bound, no one can re-plan the meeting, but the initiator. • Solution -Option 1 + Option 2 + Option 3
