We usually follow three steps:<br />
<br />
1) Design document - Includes details about the technological stack (technologies/apis/librari<wbr />es/etc) as well as the components of the system and their relationship.<br />
2) Test plan - Includes details about the planned test activities and the test encironment. It also includes information about load/stress testing.<br />
3) Technical &amp;&nbsp;User manuals - they include information about the system and how to use it. The former is specific for developers, the latter specific to users.

The design stage of SDLC: how do you design modules?

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
