Software development life cycle is the logical process of developing a system that satisfies customer needs and can be developed within the predefined schedule and cost.
Explanation:
Various phases of the software development life cycle are :
1) Analysis: First thing is to gather and analyze the requirements of the system. The information domain, function, behavioral requirements of the system are understood. These requirements are then well documented.
2) Design: After collecting and analyzing all necessary requirements, design architecture is prepared.
3) Coding: After the design, one can develop the code for the system using some programming language. During this, design is translated into a machine-readable form.
4) Testing: It is done to uncover the errors and fix the bugs.
5) Maintenance: Sometimes errors may get produced after system installation and sometimes the requirements get changed. At that time, the maintenance of the system is needed.

Which of the following is not one of the principles of agile software development method?
Answer (Detailed Solution Below)
Software Development Models Question 8 Detailed Solution
Download Solution PDFAgile software development has a major influence for a number of changes in how software developers plan and coordinate their work , how they communicate with customers and stakeholders , how software development is organized in small , medium sized and large companies from telecom and health sectors.
It basically focus on adapting to change and delivering products of high quality through simple work processes.
In agile software development model, a large product is broken into small incremental builds. These are then solved in various iterations. In agile method, every build is treated differently.
Principles of agile software development model:
- Customer involvement: During the development of a software, we are not aware of all of its requirements initially. So, customer involvement is required in this to tackle all the necessary requirements so that product is development in an efficient manner and time.
- Embrace change: It is responsive to any change in the development process
- Incremental delivery: as in agile method, product is broken into small parts and each part of that is solved iteration wise. So, it is an incremental delivery process of software development.
Some other principles are working software, interaction between individuals etc. But following the plan is not in the principles of agile software development method.
Which of the following is not a maturity level as per Capability Maturity Model ?
Answer (Detailed Solution Below)
Software Development Models Question 9 Detailed Solution
Download Solution PDFThe correct answer is "option 2".
CONCEPT:
CMM which stands for Capability Maturity Model is a benchmark to measure the maturity of an organization's software development process.
EXPLANATION:
The Capability Maturity Model is used to analyze techniques used in developing software products in any organization.
CMM has 5 different levels:
1.Initial: At this level, processes for developing software are Adhoc & not well defined.
2.Repeatable: This level focuses on project management policies establishment.
3.Define: Documentation of procedures & standard guidelines are the major focus of this level.
4.Managed: This level sets quantitative goals for software products as well as for software processes.
5.Optimizing: Using quantitative feedback, this level focuses on continuous process improvement.

Which one of the following is not a software process model?
Answer (Detailed Solution Below)
Software Development Models Question 13 Detailed Solution
Download Solution PDFCorrect answer: Option 2
Explanation:
- A software process model is a blueprint of the flow of processes that should be followed when developing a software. This model defines each task, the input and output of each task and the sequence in which the tasks should be carried out.
- The linear sequential model, prototype model and spiral model are examples of a software process model. Each model has a different approach to the flow of processes for developing a software.
- The COCOMO model, on the other hand, is a cost estimation model. It identifies the amount of labour required and the schedule to be followed.
Important Points:
- The COCOMO model, short for COnstructive COst MOdel, is used to determine the monetary cost of a software project. The cost is directly related to the manpower required (effort) and how quickly it is required (schedule).
- Either the schedule influences the effort or the effort influences the schedule. The project manager decides which of the two factors are more important and lets it be the deciding factor.
For a software project, the spiral model was employed. When will the spiral stop ?
Answer (Detailed Solution Below)
Software Development Models Question 14 Detailed Solution
Download Solution PDFAnswer: Option 1
Concept:
Spiral Model:
The spiral model, initially proposed by Boehm, is an evolutionary software process model that couples the iterative feature of prototyping with the controlled and systematic aspects of the linear sequential model.
Determining Objective: Each cycle in the spiral starts with the identification of purpose for that cycle, the various alternatives that are possible for achieving the targets, and the constraints that exist.
Risk Assessment and reduction: The next phase in the cycle is to calculate these various alternatives based on the goals and constraints. The focus of evaluation in this stage is located on the risk perception for the project.
Development and validation: The next phase is to develop strategies that resolve uncertainties and risks. This process may include activities such as benchmarking, simulation, and prototyping.
Planning: Finally, the next step is planned. The project is reviewed, and a choice made whether to continue with a further period of the spiral. If it is determined to keep, plans are drawn up for the next step of the project.
Explanation:
The spiral of software development remains operative until the software is retired. Hence Option 1 is the correct answer.
