SDLC is performed in two steps.
1. System Analysis and
2. System Design
System Analysis involves:
1. Problem Identification
2. Feasibility study and cost benefit analysis
3. System requirement analysis
System Design involves:
4. System design specifications and programming
5. System implementation, follow up and maintenance
6. Evaluation of the system
first phase in SDLC is recognition of needs
second is feasibility study
third is analysis phase
fourth is designing phase
fifth is development ,implementation and testing phase
sixth phase is maintenance phase
The follwing are the phases of SDLC.
1. Definition of the problem - Identifying the requirement
2. User Requirement Study - Interview, JAD( Joint
Application Development), Survey Method.
Outcome - Functional Specifications Document - High Level
3. Discussion and GAP Analysis - Submitting our level of
understanding to the user and conduct suitable GAP analysis
in understanding requirements.
Outcome - Detailed FS, Prototype, Use Cases, Flow charts,
Logical Data Model and Process Model.
4. Feasibility Study and Cost Benefit Analysis
5. Sign-off and establish a protocol for Change Request.
6. Design - Functional and System Design
Outcome - Dataflow and process flow design with the
suggested Design Methodology.
7. Development - Coding/programming the application.
8. Testing - Functional Testing (Black Box and White Box),
Code Testing and User Acceptance Testing (Concurrent
Testing (if multiple users are involved) and Regression
Outcome - Test Documents with error reporting at every
9. Quality Management - Software quality team will check
the system against established standards
Outcome - Certification
-- You are a project manager in a large software house of
375 staff in total. The company has been running for 5
years. The company has been CMM assessed at level 3. The
company has many external clients for whom it develops a
wide range of business applications.
-- Most of the company‘s applications are developed in
Java. The waterfall lifecycle development model is normally
used in developments.
-- The company has historically suffered from the type of
problems that are common in the software industry. In
particular systems have been delivered not always to user
requirements and containing faults. The managing director
of the company is very keen for improvements to be made in
-- You are in charge of a project team of 8 developers, 2
requirements engineers and 3 testers. Your team is just
about to start a new development.
System to Develop :( Exact Question )
-- Your team is about to start to develop a novel vehicle
navigation system for physically impaired drivers. The
navigation system not only identifies the correct route for
the driver in the normal way, but also controls the
steering wheel to navigate the car to the destination
identified by the driver.
-- A basic statement of requirements has been received from
the customer and budget and timescales have been formalised
into a contract.
Requires TASK to write :
-- You must write a short report (maximum of 1 page) for
the managing director of your company outlining how you
propose to ensure that this project improves on previous
projects in terms of delivering to user requirements and
without faults. Your report must include how you propose to
show improvement on these issues to your managing director.
Also please tell me how should I choose the best software
model when given scenarios like these ...?
