Software Development Life Cycle by Harith Yusri https://padlet.com/mharith0712/pbxlkummpu8qh71y RESD Group 9: Iterative en-us 2021-03-25 02:31:41 UTC 2026-03-01 22:06:34 UTC hello@padlet.com WHAT IS SDLC? https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350945116 Software Development Life Cycle is the application of standard business practices to building software applications.

Divided into 7 stages:
1- Planning
2- Requirements
3- Design & Prototyping
4- Develop/Coding
5- Testing
6- Maintenance
7- Software Deployment

It aims to produce quality software that exceeds customer expectations, meet deadlines and cost estimates.]]> 2021-03-25 02:35:40 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350945116 1) PLANNING https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350949254 In the Planning phase, project leaders evaluate the terms of the project. This includes calculating labor and material costs, creating a timetable with target goals, and creating the project’s teams and leadership structure.

Try to get feedback from potential customers, developers, subject matter experts, and sales reps. Planning should clearly define the scope and purpose of the application.

1- Identification of the system for development
2- Feasibility assessment
3- Creation of project plan]]> 2021-03-25 02:37:19 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350949254 2) REQUIREMENTS https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350949843 the team needs to perform an analysis of the system’s functional requirements to ensure it will meet the expectations of the target audience. Those expectations are then finalized and documented. The next step is performing a feasibility study to ensure that a system makes sense from financial, technological, and organizational standpoints.

The three primary activities involved in the analysis phase are as follows:

  1.       Gathering business requirement
  2.       Creating process diagrams
  3.       Performing a detailed analysis

Some aspects of the design include:

Architecture – Specifies programming language, industry practices, overall design, and use of any templates or boilerplate
User Interface – Defines the ways customers interact with the software, and how the software responds to input
Platforms – Defines the platforms on which the software will run, such as Apple, Android, Windows version, Linux, or even gaming consoles
Programming – Not just the programming language, but including methods of solving problems and performing tasks in the application
Communications – Defines the methods that the application can communicate with other assets, such as a central server or other instances of the application
Security – Defines the measures taken to secure the application, and may include SSL traffic encryption, password protection, and secure storage of user credentials

A prototype is like one of the early versions of software in the Iterative software development model. It demonstrates a basic idea of how the application looks and works.

The primary activities involved in the development phase are as follows :
  1.  Development of IT infrastructure
  2.  Development of database and code

The programming language is chosen with respect to the type of software being developed.

Developers find out whether their code and programming work according to customer requirements while bugs traced get fixed before proceeding to the next phase.

It is necessary to maintain and upgrade the system from time to time to adapt to future needs. The three primary activities involved in the maintenance phase are as follows:

  1.       Support the system users
  2.       System maintenance
  3.       System changes and adjustment

After the project team tests the product and the product passes each testing phase, the product is ready to go live. This means that the product is ready to be used in a real environment by all end users of the product.]]> 2021-03-25 02:44:11 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1350966871 VIDEO THROUGHOUT ABOUT SDLC STAGES mharith0712 https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351047817 2021-03-25 03:18:41 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351047817 MODELS mharith0712 https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351080022 Waterfall - the classic method of development. As each phase completes, the project spills over into the next step. One advantage of the Waterfall model is each phase can be evaluated for continuity and feasibility before moving on.

Agile - Designed by developers to put customer needs first. This method focuses strongly on user experience and input. It makes the software highly responsive to customer feedback. Agile seeks to release software cycles quickly, to respond to a changing market. This requires a strong team with excellent communication. It can also lead to a project going off-track by relying too heavily on customer feedback.

Iterative - Developers create an initial basic version of the software quickly. Then they review and improve on the application in small steps (or iterations). This approach is most often used in very large applications. It can get an application up and functional quickly to meet a business need. However, this process can exceed its scope quickly and risks using unplanned resources.]]> 2021-03-25 03:32:48 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351080022 WEBSITE mharith0712 https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351081084 2021-03-25 03:33:16 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351081084 HARDEST PHASE IN SDLC mharith0712 https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351103929 2021-03-25 03:43:21 UTC https://padlet.com/mharith0712/pbxlkummpu8qh71y/wish/1351103929
