To describe a process or operation within a system, software engineers often use pseudocode, which is a combination of English language statements in a structure that is similar to computer programming-language.

1. Select a business process (e.g., uploading a photo on Facebook or Instagram).
2. Use pseudocode to describe the process.
3. Ensure that your code is English-like and code-like.

Regardless of whether software engineers are using the waterfall methodology or the agile methodology, requirements are important. However, the requirements-gathering process and the timing of waterfall methodology may be different from that of agile methodology. Use two to three paragraphs to describe the difference between requirements in agile and waterfall.
