Software Development Lifecycle

The Software Development Lifecycle (SDLC) is a science and method of building software system applications. The SDLC is a process used to deliver software system solutions in a problem domain, in a consistent manner. It is critical to understand that the business is the primary owner of the software system that is produced as a result of the SDLC. It is also the key for any organization that builds software in-house to Learn, implement, execute, and support. The Software Development Lifecycle helps to achieve predictable results for the software products they intend to deliver when implemented properly. Its processes require strong leadership, discipline and teamwork by all involved and must be enforced by executive Management. It is the responsibility of IT to educate the business in regards to business specific roles, duties, and deliverables within the Software Development Lifecycle. IT personnel are (or should be) the experts in this subject matter and must serve as the primary educators to the business just as the company shares its knowledge of system requirements with IT.

A general Software Development Lifecycle view consists of sis specific phases that include:

• Creating a vision of the product that encapsulates the overall idea of what the product will do and how it will appear to the end-user
• Gathering the overall product vision and resources to create a comprehensive plan for building, testing, deploying, and supporting the product This also includes a specific and detailed plan for change management throughout the SDLC process.
• Implementing die plan for building the software system product
• Implementing the plan for testing the software system product
• Implementing die plan for deploying the software system product
• Implementing die plan for supporting the software system product after it has been put into production.

It is not sufficient to only know how to write code well within the SDLC. A software engineer must know much more than just how to produce good code. A Software Engineers role within the Software Development Lifecycle process includes but is not limited to:

• A strong understanding of business requirements
• The ability to write comprehensive, and simple test plans and later invoke them
• In some cases, the ability to write Technical Specification Documentation
• The ability to understand and follow software system architecture diagrams, design patterns, and development standards
• The ability to understand database schemas
• The ability to work well with others on the software system project team
• The ability to ask the right questions
