“Planning” is the very first stage of an asset’s life cycle. In this stage, building managers take observations of current resources and equipment conditions. They may also verify the resources needed to move forward with replacing an asset.

What is maintenance in program development life cycle?

The Maintenance Phase

As the last phase of the system development life cycle, it involves making use of feedback from end-users to make changes. This also involves addressing any bugs that may still be present in the system.

What is the first task of the maintenance phase quizlet?

The maintenance phase starts the process all over again, which is why the process is considered a cycle. Explain the tasks performed during the system definition phase of the systems development life cycle. The first step is to define the goals and scope of the new information system.

What is maintenance in waterfall model?

Maintenance. After the deployment phase, the next step is to provide support and maintenance for the software, making sure it runs smoothly. If the client and users come across errors/defects/bugs during use, fixing them is the main purpose of this stage.

What is the purpose of maintenance phase?

The purpose of the maintenance phase is to provide three key outcomes: maintain software functionality, make upgrades to the coding, and ensure any repairs needed to the software are completed.

Why maintenance phase is the longest phase in SDLC?

The primary reason that the maintenance phase last longest is the life of the software. Most software programs remain in operation until they become obsolete due to changes in a user’s needs or until the cost of maintaining the software becomes prohibitive to future use of the software.

What are the 6 stages of a waterfall?

The waterfall model has six stages: requirements, analysis, design, coding, testing, and deployment. During the requirements stage, developers write down all the possible requirements of a system in a requirements document. The document defines what the system should do, but not necessarily how it will work.

Is maintenance a phase of waterfall model?

Another important phase of this model is the maintenance model. Updating the product, patching any bugs and errors and developing other essential components as per feedback to make this full software is done in this stage.

What are the four phases of waterfall approach?

What is SDLC and waterfall model?

The waterfall model is a linear, sequential approach to the software development life cycle (SDLC) that is popular in software engineering and product development. The waterfall model emphasizes a logical progression of steps.
