Hello again! Today I’m gonna talk about the 3rd and 4th stages of the systems development life cycle.
The Design stage describes how the proposed system is to be developed. Each design is specific to the system’s requirements.
There are several things to be achieved by the end of the design stage of SDLC. Some software development models approach this stage in a rather simple manner.Developers work together and talk about the ways of developing the program while staying within the budget set out by the company. The workflow of the software is drafted in this stage. The initial programs are created in this part of development model.
The key deliverables of Design are :
-Functional Specification Document
-data, processes, inputs, outputs, etc.
-Technical Specifications Document
Once the design has been established then it is time to implement the design. Testing has been completed and it is now time to convert the physical system specifications into a working and reliable solution. Developers have to make sure their created programs will work well in different environments. Once testing is finished and the software is proven good for implementation, it is released to the company to see if it works. It’s expected that on first days, developers will face serious challenges of fixing different bugs as they are discovered when the system is first used.
Coding, Testing and Installation are the three main tasks of the implementation stage.
This is an exceptional video explaining implementation in an easy manner..I would recommend the watch 🙂
Key Deliverables of Implementation are:
-Fully Installed system
-Fully trained users
-User and Operational Documentation
