Inception phase review • Techniques & Tools • Stakeholders, Roles, and Responsibilities (SRR) Table • Root Cause Analysis (RCA) • Data Flow Diagrams (DFDs) • Organizational Impact • Non-functional Requirements (NFR) • Risk • Cost/Benefit Analysis—ROI Goal: Evaluate feasibility of project and get consensus between client and team to proceed (scope)
MIS 374 SDLC*-- Inception Phase tasks 1. Identify organizational impacts. 2. Determine project scope, objectives, constraints, performance criteria & risk. 3. Determine initial requirements. 4. Build a development team and create a work plan. Task order, iteration, and collaboration with users will depend on project characteristics. * SDLC: System Development Life Cycle

Risk Analysis Steps • Identify tasks and deliveries that are risky. • Determine risk reduction strategies to lower the likelihood of each risk.

EMS Scheduling Project This was a project to automate scheduling of drivers and medical staff for the City of Austin’s Emergency Medical Services.
Objectives • Automate scheduling • Alert managers to scheduling conflicts • Staffing reports • Create an electronic scheduling form

Risk Summary • All projects have risk • You may not meet the criteria expected – cost/benefit, number of resources, time, etc • You may not achieve established goals – functionality or scalability or commitment • Risk occurs in proportion to the scope of the project • The key is to identify and manage the risks.
In pairs or alone, use web resources, books, internships & past classes to fill in as many ideas as possible in the Risk Evaluation form. Assume you have completed the DFDs and plan to find open-source software. Give risk reduction suggestions for all “-1” ratings on Risk Reduction Strategies form (on back) Risk Evaluation--Exercise 8
Client Project task this week Group Project 2 – Cap Ex • Due Wednesday, Feb 13th, 2pm Resources: • GP1 examples for SRR & RCA are posted on Schedule - Day 6, Jan. 31 • Examples of all GP2 deliveries are on Resources page
Group Project 2 • 10. Complete a Gantt chart that shows your plans for completion of the system, tested and installed. Create a work breakdown structure (clear simultaneous phases with A-D-C-R loops), assign team members, and estimate times and dates for each activity. Assume you may not add team members, but must allocate all tasks among the team members assigned in class and the relevant staff at Natural By Design. For full credit you need at least 100 detailed activities. • And, yes, we understand that you don't have enough knowledge of this project and the environment to make realistic detailed plans. This is an assignment to force you to practice detailed planning techniques with the limited information you have. Be as realistic as possible.
Cost/benefit analysis (CBA) • Estimate project development costs • Estimate operational costs after project • Estimate financial benefits based on annual savings and increased revenues • Calculate CBA using complete list of costs and benefits • CBA uses net present value (NPV), payback period, return on investment (ROI) techniques
Steps to Conduct Cost/Benefit Analysis • Identify Costs and Benefits • Assign Values to Costs and Benefits • Determine Cash Flow • Determine Net Present Value (NPV) • Determine Return on Investment (ROI) ROI = (Benefit – Cost)/Cost * 100
Intangibles in Cost/Benefit • Intangible benefits are harder to quantify in dollars • Increased levels of service • Customer satisfaction • Survival • Need to develop in-house expertise • Intangible costs are harder to measure in dollars • Reduced employee morale • Lost productivity • Lost customers or sales
Calculate those values over time available on Resources page
Non-Profit ROI Example Assumptions for Non-Profit Client • IT team (MIS 374) work donated per semester Our team consists of 5 members working 1 hour per day over a period of 90 days (the duration of our project according to our project plan) 5 team members * 90 days * 1 hour/day * $15/hour = $6750 Each team member could earn at least $15/hour at an undergraduate IT consulting internship One future team will also donate time in updating the CRM system in 2007 • Benefits--Donation amounts will increase by 30% yearly, while number of donation transactions will increase by 50% yearly: Year Number of donations Donation amount 2006 5 $500 2007 8 $650 2008 11 $845 2009 17 $1099 • Costs-- Website registration at $10 flat fee yearly Additional server space required at $150 yearly PayPal charges $0.30 + 2.9% fee per transaction
