Final answer:
After collecting all facts and data in a systems survey, the activity that typically follows is to perform data analysis.
Step-by-step explanation:
Once all facts and data have been collected in the systems survey, the next step is typically to perform the data analysis. This involves taking the information that has been gathered and interpreting it to make informed decisions about system improvements, developments, or implementations. It is a critical step that supports the decision-making process within the context of systems design or upgrade.
Data analysis is often preceded by a preliminary investigation, which helps in understanding the problem or system in question. After data analysis, the process may move on toward system implementation or other related activities such as designing and conducting studies, summarizing articles, or drafting projects in various contexts.
