Please answer all questions - True/False
The SDLC (Software Development Lifecycle) is a framework defining tasks performed at each step in the software development process.
Understanding the user’s needs is mission critical to a successful SDLC.
The Waterfall methodology is the most straightforward of all of the SDLC methodologies, because there are strict phases and each phase needs to be completed first before going to the next phase. There is no going back.
An advantage of the Iterative model is that it quickly delivers a working product.
An advantage of the V model is that each stage has a corresponding testing activity which helps to identify missing requirements, and incorrect design early in the life cycle.
The DFD (Data Flow Diagram) should be used in lieu of a descriptive prose representation of a user’s process.
The PFD (Process Flow Diagram) can illuminate new processes and steps that could have been missed because it requires users to go through each phase of their system as it occurs or in an actual sequence.
A requirements document explains the logical flow of processes in a project.
The first step in LDM (Logical Data Modeling) is to create a master table.
A legacy system is an existing application system in operation.
BPR (Business Process Reengineering) is a methodology that is used to calculate lead time for tasks in a project.
The first step in applying successful BPR is to develop an approach to define the existing system and extracting its existing data elements and applications.
Acceptance test plans can be defined as a set of tests that if passed will establish that the software can be used in production.
ISO 9000 is a set of standards that define how projects are meant to be implemented.
There are three major steps that are necessary to move the application into a production environment: user training, IT’s role, and the preparation steps for going live.
Explanation / Answer
1. The SDLC (Software Development Lifecycle) is a framework defining tasks performed at each step in the software development process.
ü (True Ref. SDLC Overview Page 1)
ü SDLC is a framework defining tasks performed at each step in the software development process.
2. Understanding the user’s needs is mission critical to a successful SDLC.
ü (True Ref. SDLC Overview Page 1)
ü The SDLC aims to produce high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.
3. The Waterfall methodology is the most straightforward of all of the SDLC methodologies, because there are strict phases and each phase needs to be completed first before going to the next phase. There is no going back.
ü (True Ref. SDLC Overview Page 4)
ü In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases.
4. An advantage of the Iterative model is that it quickly delivers a working product.
ü (True Ref. SDLC Overview Page 8)
ü The advantage of this model is that there is a working model of the system at a very early stage of development, which makes it easier to find functional or design flaws. Finding issues at an early stage of development enables to take corrective measures in a limited budget.
5. An advantage of the V model is that each stage has a corresponding testing activity which helps to identify missing requirements, and incorrect design early in the life cycle.
ü (True Ref. SDLC Overview Page 16)
ü The advantages of the V-Model method are easy to manage due to the rigidity of the model. Each phase has specific deliverables and a review process. Unit Testing, Integration Testing, System Testing, Acceptance Testing
