Preferred Requirements Gathering Techniques - 3

By: Crestech

Interfaces Analysis.
Missing or incorrect interfaces are often a major cause of cost overruns and product failures. Identifying external interfaces early clarifies product scope, aids risk assessment, reduces product development costs, and improves customer satisfaction. The steps of identifying, simplifying, controlling, documenting, communicating, and monitoring interfaces help to reduce the risk of problems related to interfaces.

Please see attached Requirement Analysis Template

b) The feasibility Study
The Feasibility Study uses technical information and cost data to determine the economic potential and practicality (i.e. feasibility) of a project. The Feasibility Study uses techniques that help evaluate a project and/or compare it with other projects. Factors such as interest rates, operating costs, and depreciation are generally considered. The following questions are answered during feasibility study

An abstract definition of problem
Formulation of different Solution strategy
Examination of alternative solution strategy (in terms of benefits, Resource requirement, costs etc)
Cost and benefit analysis to determine the best strategy

Who uses it?
Technical Architect, Business Analyst, Configuration Manager, Development Manager, Project Manager, IT Manager, System Administrator, Test Manager, Documentation Manager, Technical Writers, System Administrator.

When is it used?
The Feasibility Study analyses potential solutions against a set of requirements, evaluates their ability to meet these objectives, describe a recommended solution, and offer a justification for this selection.

c) Project Planning
When a project is estimated to be feasible, project planning is done. Project planning consist of the following steps

Effort, Cost, Resource and Project Duration planning
Risk Analysis and mitigation plan
Project Scheduling
Staffing organization and Staffing Plan.
