The possible costs exist in two aspects. One is the hours spent for the project, the other is the possible cost spent by clients.

– Clients meeting: 1.5 hours/per week (Including prototype and architecture demonstration)

– Contact with clients through email and phone call: 2 hours/per week

– Team meeting: 1.5 hours/per week– The costs spent by the clients mainly contain the cost of leasing

the web server, according to clients description.

We now describe the benefits from this project, the current activities and resources used, and the reduced percentage and corresponding saved time by using this project.

The table below describes the projected Return on Investment for Online Application System we are building. The year-to-year effort cost assumes maintenance in hours per year. In the first maintenance year, we might make more effort to maintain and fix the system, in order to let it run more efficient than before.

 From the ROI Analysis graph below, we can see that Los Angeles Child Guidance Clinic will get its return-on-investment almost immediately.

04/18/23 9

04/18/23 10

LOS-1: System Availability

The system shall at minimum be operational 95% of the time.

Product Strategies: Optimized data structures and queries. Infrastructure testing. Connectivity to the internet

Analysis: Maintain the system availability, timely fix the bugs occur in the system.

LOS-2: System Query Time

The system shall generate the reports within one minute or less

Product Strategies: Optimized data structures and queries.

Analysis: Optimized data structures and database logical design can efficiently satisfy this requirement.

04/18/23 11

LOS-3: System Data Maintenance

The system shall maintain user profile and application information for at least 6 months. At best a year.

Product Strategies: Optimize database, data storage techniques to allow for at least 6 months of textual data. Analysis: Only if we optimize database, data storage techniques, we can ensure the continuous data maintenance, or it might break down, due to the data overload.

1. The risk that we may not be able to make up for several weeks of lost time from the previous project.

SolutionsSolutions

Successfully reschedule the time, positively contact with clients, and retrieve more project details.

Frequently conduct the team meetings, client meeting to analyze the desired system.

2. The risk regarding that what does “flexibility in the structure of the application” specifically mean and the different positions information is quite not clear.

SolutionsSolutions

We discussed this issue using our prototype, so that we better understood the definition.

Learn about different positions description then we can design each field for each position better.

04/18/23 14

1. The project should be done with the knowledge of Struts-Spring-Hibernate, which most of us have a few experience with it.

Deeply learn this technology. Inherit some previous code. MitigationsMitigations

2. This system needs the security to database from hacker attacks. While since even though we will try our best to improve the system security for important data, the system still can’t avoid the possibility of being attacked by hacker.

MitigationsMitigations

Provide the security protection for system to the maximum, like adopting the hardware protection. .

Timely update the security mechanism for the system. 04/18/23 15

3. Uncertainty of the kind of web server the client will choose, still considering what size of web server they need.

MitigationsMitigations We provided some available and suitable choices for clients. Discuss the actual data size and make the decision as soon as possible.

4. Lack of way in which to combine the current and new website we develop.

MitigationsMitigations Negotiate with the LA Studio to find solutions. Further discuss it with their technology staffs.

Life cycle strategy - Rebaselined Foundations phase

• Duration: 1/9/12- 2/15/12 • Concept: Since there might be some changes during

the semester break, such as team reformation, new policy from the client’s organization, so, in the early weeks of Spring semester (csci577b), each team has to rebaseline the project.

• Deliverables: Updated documents• Milestone: Rebaseline Development

Commitment Review• Strategy: One Incremental Commitment Cycle

04/18/23 36

Life cycle strategy - Development phase

• Duration: 2/16/12- 5/4/12 • Concept: In this phase, we focus on implementation and

transition of the project. We focus on code and tests (unit tests, component tests and system test, acceptance test). And we perform site installation and activation.

• Deliverables: Transition Package• Milestone: Operation Commitment Review• Strategy: Three Incremental Commitment Cycle

– construction iteration 1: 2/16/12-03/23/12– construction iteration 2: 03/24/12- 4/20/12– transition iteration: 4/21/12- 5/4/12

Resource Estimation – Scale Factors

04/18/23 44

Resource Estimation – Modules

04/18/23 45

Resource Estimation -Product cost driver

Cost Driver

Vale Rationale

RELY LowAs an application website, the software failure of this project will just cause some inconveniences and easily recovered.

DATA NominalAs a simple application system, the ratio of bytes in the test database to SLOC in the program should be nominal.

CPLX

Low, Except Application

which is Low+50%

There are no direct hardware operations and complex data structure designs in the project. It is just simple read/ write/modify operations. But the CPLX of Application module should be a little higher because the type of application varies.

RUSE Low+50%This system is an independent project rather than a part of a product chain. Maybe reuse across some modules in the project.

DOCU NominalAs a course project, we write and maintain the documentations as the schedule.

04/18/23 46

Resource Estimation – Platform cost driver

Cost Driver

Value Rationale

TIME Nominal Time constraints for the system should be within reasonable limits.

STOR Nominal There is no specific constrain to the storage in the system.

PVOL Nominal There is no specific constrain to the platform in the system.

04/18/23 47

Resource Estimation – Personnel cost driver

Cost Driver

Value Rationale

ACAP NominalAll students have some project experiences, so they have some capabilities to analysis the system.

PCAP Low+50%Developers are all students, so the capability of programmers as a team should be between low and nominal.

PCON Very HighAll of the developers will stay with the project whole year. And other stakeholders will do the same.

APEX Nominal+50%Some team members have developed some similar projects before.

PLEX Low+50%Several developers have some basic experience of JSP but not much.

LTEX Nominal+50%As computer science students, developers have gained some knowledge of languages and tools.

04/18/23 48

Resource Estimation –Project cost driver

Cost Driver

Value Rationale

TOOL Nominal Basic life-cycle tools, moderately integrated.

SITE Nominal Part of the development is assigned to another company: LA Design Studio.

SCED Nominal As a project of a class, we should develop according the schedule.
