Commercial off the shelf


Okay, Im studying COTS now for tomorrow 10 % quiz which I have mistaken it to be a 20 % test.
But... 10 % still a lot right. My A depends on it hor.

This is what I studied :

Decision Analysis Phase:

  • Research technical criteria and options
  • Solicit proposals or quotes from vendors
  • Validate vendors claims and performances
  • Evaluate and rank vendor proposals
  • Award contract and debrief vendors
Candidate Systems Matrix:
It is use to compare and document the chracterisitics of the different candidate system. It is more to a comparative tool than an anlaytic tool.

Feasibility Assessment Matrix:
It is use to evaluate and rank the different candidate system. It is usually used with the candidate systems matrix to give a complete comparism as well as the analysis and ranking of different proposed solutions.

Classification of benefits:

Tangible
Benefits that could be quantified
  • few processing errors
  • increasing sales
  • faster response time
  • elimination of job steps
  • reduces expenses
Intangible
Benefits that are impossible/ not easy to quantified
  • Custmomer's goodwill
  • company's reputation
  • Employee morale
  • Customer service
  • Better decision making

Classification of costs:

Development costs:

It is one time cost that would not recur after the completion of project.
  • production cost
  • equipment cost
  • personal cost
  • training cost
Operation costs:
It is the on going cost that incurred to support and maintained the system until the system retired or being replaced.
  • salaries
  • software liscence
  • supplies (ink, paper...)
  • utilities
Present value
Payback analysis
A technique for determining when an innvestment will pay for itself.
Accumulate cash benefits for each year until sum equals the initial cost incurred to determine the payback period.
The shorter the payback period, the faster the organisation will get back it investment outlay.
(It is the duration of how long the investment on the system would take to return the cost of implementing the system.)

Payback analysis = lifetime cost / estimated lifetime benefits *

Return on Investment
A technique for comparing lifetime profitability of alternative products
return from an investment and the amount invested.

ROI= (Estimated benefits - estimated lifetime cost)/estimated lifetime cost)

Net Present value (NPV)
Discounted costs...
NPV = Sum of discounted benefits - sum of discounted costs

System proposal
The system proposal is used to communicate a recommended solution to the system owner and business users.
This is usually done in an oral presentation or a report.

Contract Review
The project team submits its recommendations to the board for review and decision making.
The results will be communicated to all parties and the project team will negotiaite with the selected vendor to create the contract.
The project team and legal counsel negotiates the contract with the selected vendors base on several term and condition such as : price, deliverables, milestone, dates, support, maintenance.

(submit to board -> review and decide -> result -> T-spin negotiate to create contract -> t and legal go through term and conditions )

GAP ANALYSIS

Purpose: A gap analysis must be performed to determine which business requirements are not fulfilled by the package's capabilities and features.

A comparison of business and technical requirements for a commercial application package against the capablitites and features of a specific commercial application package for the purpose of defining the requirements that cannot be met.

Gap resolutions:

  • Design a work -around : Look for alternatives
  • Make the business fit the package : Modify the business process to suit the package solution
  • Customize the package to suit the business : modify the packaged software to suit the business requirements



Okay, this is merely ctrl c , ctrl v.
Argh.
goodnight.
