As part of the alignment stage of a business change, an IT technician is investigating...

The notes combine quantitative measures and findings from examining artefacts. The “low response rates totalling 35%” and “users score the user interface design 2.4 out of 5” strongly indicate a survey was used, because surveys are a quantitative investigation technique designed to gather standardised responses from many users and produce numerical summaries (such as average scores and response rates). The business analysis process model explicitly lists quantitative investigation techniques such as surveys.

In addition, “there are 7 redundant data items on the forms” is a classic output of document analysis—reviewing the content and structure of business documents to understand what data is captured, whether it is necessary, and how it is used. The documentation explains that analysing documents (including samples of completed documents) can clarify key data items and reveal insights into how work is performed and what information is truly needed. It also lists document analysis among quantitative/fact-finding techniques used in the early stages of investigation.

Finally, “40 new entrant forms are completed per week” is consistent with a quantitative approach (counting volumes), which commonly accompanies surveys and document-based sampling/review in early investigation. Therefore, the best match is Surveys and Document Analysis (Option A).
