What is the Software Development Life Cycle What are the differences between them?
Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process.
Difference between SDLC and STLC:
|It helps in developing good quality software.||It helps in making the software defects free.|
|SDLC phases are completed before the STLC phases.||STLC phases are performed after SDLC phases.|
Which is not a software life cycle model?
Detailed Solution. Capability Maturity Model (CMM) specifies an increasing series of levels of a software development organization. The higher the level, the better the software development process, hence reaching each level is an expensive and time-consuming process. Unlike other models, it is not a life cycle model.
What is agile development life cycle?
The Agile software development life cycle is the structured series of stages that a product goes through as it moves from beginning to end. It contains six phases: concept, inception, iteration, release, maintenance, and retirement.
What is analysis phase in SDLC?
The Analysis Phase is where you break down the deliverables in the high-level Project Charter into the more detailed business requirements. The Analysis Phase is also the part of the project where you identify the overall direction that the project will take through the creation of the project strategy documents.
What are the important phases of project life cycle?
The project management life cycle is usually broken down into four phases: initiation, planning, execution, and closure. These phases make up the path that takes your project from the beginning to the end.
Who uses the software development life cycle?
Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality softwares. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.
Which model is best for software development?
When it comes to software development, Waterfall is the most traditional and sequential choice. Although it's usually viewed as an ”old school” or outdated method, it's helpful to understand the history and structure of Waterfall to better appreciate the flexibility of more modern methodologies.
What is cohesion in SE?
Cohesion: Cohesion is a measure of the degree to which the elements of the module are functionally related. It is the degree to which all elements directed towards performing a single task are contained in the component.
What are the 6 phases of program development life cycle?

What is difference between agile and waterfall?
Agile and waterfall are two distinctive methodologies of processes to complete projects or work items. Agile is an iterative methodology that incorporates a cyclic and collaborative process. Waterfall is a sequential methodology that can also be collaborative, but tasks are generally handled in a more linear process.
What is difference between verification and validation?
Validation is the process of checking whether the specification captures the customer's requirements, while verification is the process of checking that the software meets specifications. Verification includes all the activities associated with the producing high quality software.
What is V model in software testing?
The V-Model is a model used to describe testing activities as part of the software development process. The V-Model can be interpreted as an extension of the Waterfall development model, which describes the testing activities as one of the last steps in a sequential development process.
Which is the longest phase in software life cycle?
3) Implementation / Coding: On receiving system design documents, the work is divided in modules/units and actual coding is started. Since, in this phase the code is produced so it is the main focus for the developer. This is the longest phase of the software development life cycle.
What is difference between SDLC and Agile?
Agile is a methodology following an iterative approach used for project management purposes. SDLC is a process of design and development of a product or service.
