Systems Development Life Cycle
10 important questions on Systems Development Life Cycle
What are traditional problems in IS development? Explain if possible.
- Underestimating the maintenance cost: maintenance cost is big part of the total costs
- Insufficient analysis: you should do enough analysis upfront, the later you find an error the more it will cost
- Project estimation and planning
What are the problems for doing cost estimation?
- New by definition
- Influencing factors
- New technologies
- Scope creep
What steps are in the information systems life cycle?
2. System analysis: What are the elements of the problem?
3. System design: try to figure out the solution.
4. System implementation
(5. System maintenance)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the phasing principle?
In every phase you do the following:
- You check to results of the previous phase
- You check the network of activities
- You check the techniques
- You check the delivarable items
- You monitor and manage
- You have a final report
Eventually you approve the decision
What are the delivarable items of the phasing principle?
For the system analysis phase this will be the Funtional Specification: project plan (time and budget), quality management plan, acceptance test specification
For the system design phase this will be the System Design Specification: a refined project plan, a refined quality management plan
And for the system production phase this will be modules and program code: so user documentation, and acceptance test description
What does RAD and JAD stand for?
JAD = Joint Application Design
What are (next to the traditional development) other alternative design methods for the system?
What are disadvantages of prototyping?
The system can always be improved, it never stops
What are the two types of prototyping? Explain them.
- Throw-away prototyping: prototype till you know what you want and built it in real. In reality there is not time for this.
What is incremental development?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
