Slide 1

´╗┐Attainability Analysis for a Software Project Dr. Pedro Mejia Alvarez Seccion de Computacion, CINVESTAV-IPN

Slide 2

Feasibility Analysis "A measure of how useful or down to earth the advancement of a product framework will be to an association. This examination repeats for the duration of the life cycle."

Slide 3

Planning Planned Project Existing System Support Analysis Production System Business Requirements Implementation Design Technical Design Feasibility Checkpoints "crawling duty approach"

Slide 4

Planning Planned Project Existing System Support Analysis Production System Business Requirements Implementation Design Technical Design Feasibility Checkpoints frameworks investigation - think about direness? unpleasant cost evaluate frameworks investigation - definition clearer scope, refined cost gauge frameworks outline - determination alter scope, plan, costs frameworks plan - acquisition choice check before letting contracts frameworks plan - detail plan one final opportunity to wipe out or scale back

Slide 5

Planning Planned Project Existing System Support Analysis Production System Business Requirements Implementation Design Technical Design Feasibility Analysis T echnical can framework be created? O perational can association assimilate the change? E conomic what is business support? S chedule can framework be executed in time accessible?

Slide 6

People Technical Feasibility Technology Is the innovation or arrangement handy? Do we right now have the vital innovation? Do we have the important specialized ability?

Slide 7

People Operational Feasibility Is the issue worth settling? Will the answer for the issue work? How do the end-clients and administrators feel about the issue (or arrangement)?

Slide 8

People Schedule Feasibility Can the venture due dates be met? What will it cost to quicken advancement?

Slide 9

Economic Analysis Cost gauges securing or improvement costs operation and upkeep costs Benefit gauges unmistakable advantages immaterial advantages

Slide 10

Estimating Costs obtaining or advancement (one time) operation and support (continuous) in these cost classifications work force hours PC utilization media and supplies hardware and programming

Slide 11

Estimating Acquisition Cost Shop the Vendors (casual) Request for Proposal (RFP) Request for Quote (RFQ)

Slide 12

Estimating Development Cost split venture up into undertakings appraise SDLC assignments autonomously utilize life cycle cost demonstrate e.g., 1-3-3-3 display exploit relationship/encounter what amount have comparable activities taken a toll? compute work point metric gauge "size" of venture from data sources, yields, and so on apply efficiency rate

Slide 13

Estimating Operation and Support customer/client faculty specialized staff media and supplies hardware and programming bolster repair upgrade

Slide 14

Estimating Tangible Benefits lessened costs manual operations PC operations modified choices expanded income new administrations separated item speedier conveyance better quality bigger piece of the pie

Slide 15

Estimating Intangible Benefits data quality accuracy auspiciousness coordination introduction work fulfillment participative outline work enhancement enhanced devices outer standing responsiveness corporate picture

Slide 16

Economic Analysis (proceeded) customary capital arranging methods apply payback investigation rate of return net present esteem

Slide 17

January 1996 Payback Analysis decides to what extent it will take for collected advantages to overwhelm accumulated and proceeding with costs most organizations need snappy payback 3-5 years is average

Slide 18

% Return on Investment (ROI) decides the lifetime gainfulness of various speculations ROI = (benefits - costs)/costs) Annual ROI is normal measure

Slide 19

Net Present Value (NPV) decides the lifetime productivity of various ventures NPV = marked down advantages - reduced costs Preferred system in numerous associations
