University of Southern California Center for Systems and Software Engineering 18 Example Detailed Schedule

University of Southern California Center for Systems and Software Engineering Exploration Phase During this phase, explore current system and identify initial scope of the system Valuation Phase During this phase, initial understanding of the desired system must be accomplished. This is achieved by defining the scope of the project so all stakeholders are in concurrence. Feasibility analysis and prioritization of the tasks must also be done here Foundations Phase During this phase, prototyping must demonstrate the architecture’s feasibility and stability. Risks and plans to minimize risk must also be assessed and developed in this phase. Additionally an appropriate development schedule should be created. Furthermore, cost estimates must also be conceived here. Moreover, an operational impact analysis must be completed to observe how useful the proposed would be to the customer and user Rebaselined Foundations Phase Development Phase Example 2.3 Phase Deliverables and Completion Criteria ArtifactDue dateFormatMedium Client Interaction Report9/17/2006.doc,.pdfSoft copy Valuation Commitment Package  Operational Concept Description (OCD) Early Section  Life Cycle Plan (LCP) Early Section  Feasibility Evidence Description (FED) Early Section 09/18/2006.doc,.pdfSoft copy Evaluation of Valuation Commitment Package09/27/2006.xlsSoft copy Project EffortEvery MondayTextER system Project PlanEvery Wednesday.mpp,.pdfSoft copy Progress ReportEvery Wednesday.xlsSoft copy Risk AnalysisEvery WednesdayTextDART system For Milestones and suggested deliverables, check lecture 3

University of Southern California Center for Systems and Software Engineering Project Deliverables -Provide a list of artifacts to be delivered. -The precise artifacts to be delivered depend upon your project’s type. -The contents of the list depend on the type of project -with certain COTS projects having different artifact delivery requirements than custom development projects, so an indication of the project type would be appropriate here. -For each artifact, provide its due date, format (word, pdf, etc) and delivery medium (hard copy, soft copy, etc). -

University of Southern California Center for Systems and Software Engineering Example of COCOMO II Scale Drivers 28 Scale DriverValueRationale PRECHIGHThe development team is familiar with this type of online application. Although, concurrent development associates with extensive new hardware and operational procedures. FLEXHIGHThe system needs to considerably conform to pre-established requirement from the client and external interface specifications, e.g. GPRS services and Internet protocols. RESLHIGHAll critical risk items, schedule, budget and internal milestones are identified. However, there is some uncertainty in hardware compatibility. TEAMHIGHEach stakeholder has considerable consistency of objectives and cultures, and considerable ability and willingness to accommodate others’ objectives. In addition, the stakeholders have basic experience in operating as a team. PMATNOMINALThe development team follows ICSM-EPG, which the processes are defined and repeatable but the result may not be consistent, CMM Level 2.

University of Southern California Center for Systems and Software Engineering Example of COCOMOII Cost factors 29 Cost DriverValueRationale RELYNOMIN AL Although, some modules in this project depend on this module, the effect of the software failure is moderate and losses are easily recoverable. DATALOWThe ratio of bytes in the testing database to SLOC in the program is approximately less than 10 because the database will store only information of plant services, which are employee id, check-in time, check-out time, each plant conditions, and short comments, of 20 locations in each week. DOCUNOMIN AL Because the development process follows ICM-EPG, the document for life-cycle needs is normal. CPLXNOMIN AL It contains simple message passing control, standard math and statistical routines for generating reports, and simple I/O process includes device selection from bar code scanner or user interface, status checking of bar code scanner, and error processing. Additionally, it has simple structural changes and uses simple widget set. RUSELOWIt is not intended to be reused for the future project. TIMENOMIN AL The percentage of available execution time expected to be used by the system and subsystem consuming the execution time resource is less than 50% because this system is used when a worker does plant services which are preformed once a week, and this system is used by a manager to review plant service reports which at most couple times a week. STORNOMIN AL The percentage of available storage expected to be used by the system and subsystem is less than 50% because the most data is general text and the information of plant services such as plant conditions and comments are condensed. PVOLLOWMajor changes of the platform, i.e. Apache Tomcat, JDK, MySQL, and web browsers, are approximately every year. ACAPVERY HIGH The analysts have the ability to analyze, design, communicate, and cooperate very well. PCAPVERY HIGH Programmers are capable, efficient and thorough. They are able to communicate and cooperate very well. PCONNOMIN AL We have 8 team members in CSCI577a and 5 team members in CSCI 577b that suitable for our project sizing. APEXNOMIN AL The average experience of the team members for this online web-based application is about one year. LTEXNOMIN AL The development team plans to develop this web-based application with JSP, HTML, and Java script, and uses SQL language to query information from the database. The tools for programming are Dreamweaver and Eclipse. Therefore, the language and tool experience is nominal because team members have at least one year experience with these languages and tools. PLEXLOWThe server platform is web server Apache Tomcat with JDK version 1.5, and database is MySQL. Although, all developers have this platform experience, this module need implementation an user interface on PDA and input with bar code scanner which our developers have less experience. TOOLLOWThe software tools development team plan to use is just simple, frontend, backend CASE, and supporting little integration. There is no support for life-cycle. SITEVERY HIGH Six of eight team members are on-campus students; only two team members are off-campus students. Additionally, we use wideband electronic communication and occasional video conference. SCEDNOMIN AL The schedule is fixed for 12 weeks in Fall semester and 12 weeks in Spring semester.
