For example, Figure 1 depicts the Scrum construction life cycle whereas Figure 2 depicts an extended version of that diagram which covers the full system development life cycle SDLC.

Deployment Maintenance 1 Requirement gathering and analysis: Business requirements are gathered in this phase. This phase is the main focus of the project managers and stake holders. How will they use the system? What data should be input into the system? What data should be output by the system?

Introduction

These are general questions that get answered during a requirements gathering phase. After requirement gathering these requirements are analyzed for their validity and the possibility of incorporating the requirements in the system to be development is also studied.

Finally, a Requirement Specification document is created which serves the purpose of guideline for the next phase of the model. The testing team follows the Software Testing Life Cycle and starts the Test Planning phase after the requirements analysis is completed.

In this phase the system and software design is prepared from the requirement specifications which were studied in the first phase. System Design helps in specifying hardware and system requirements and also helps in defining overall system architecture.

The system design specifications serve as input for the next phase of the model. In this phase the testers comes up with the Test strategywhere they mention what to test, how to test. 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. After the code is developed it is tested against the requirements to make sure that the product is actually solving the needs addressed and gathered during the requirements phase.

During this phase all types of functional testing like unit testingintegration testingsystem testingacceptance testing are done as well as non-functional testing are also done. As soon as the product is given to the customers they will first do the beta testing.

Rapid Application Development

If any changes are required or if any bugs are caught, then they will report it to the engineering team. Once those changes are made or the bugs are fixed then the final deployment will happen.

Once when the customers starts using the developed system then the actual problems comes up and needs to be solved from time to time. This process where the care is taken for the developed product is known as maintenance.Define the business webkandii.com must consider the bigger business picture and focus on market concerns.

This includes exploring how the new functionality will improve your organization's presence in the market, how it will impact profitability, and how it will impact the people within your organization.

It's a profession, but it's also a set of techniques that anyone can apply to achieve goals and manage project work more effectively.

3 project close-out phase is complete. The product life cycle begins at the moment the product begins to be used, sold or placed in operation, thus producing the benefits that justified the project in the first. Life-cycle cost analysis (LCCA) is a method for assessing the total cost of facility ownership.

Life-Cycle Cost Analysis (LCCA) | WBDG Whole Building Design Guide

It takes into account all costs of acquiring, owning, and disposing of a building or building system. Jul 20,  · Let’s suppose, you’re about to board on a software or web development project that you want to take your business to the next level, you may be surprised to learn that the software development life cycle starts long before the project .

It also ensures that a system is maintained in a validated state throughout its entire life cycle, from conception through retirement. We will discuss the phases within the SDLC, and how these form the basis for any CSV project.
