Stages of the System Development Lifecycle – Design

8 Mar

In my previous posts I have introduced the SDLC and discussed the first two stages of the SDLC, planning and analysis. In this post I will discuss the third stage of the SDLC which is design.

The main objective of the Design Stage of the SDLC is to create a system design that meets the main user requirements for the system. There is a change from’why’ questions in the analysis stage to ‘how’ questions in the design phase. There is two different aspects to the design stage, the logical design of the system and the physical design of the system.

In this stage an appropriate Database Management System (DBMS) must be developed along with system security standards. The interface of the system must be designed. Data Capture Requirements, standards for printed report production and system navigation methods must also be developed in this stage.

The key deliverables of the design stage are:
• A functional specifications document which outlines the data, processes, inputs and outputs that will be included in the system.
• A technical specification document which outlines the programs, files and network that will be included in the system.
• An implementation schedule outlining key dates in the SDLC.

Here is a link to a YouTube video that will aid your understanding of the Design phase of the SDLC:
