hi, your requirement is not fully clear right now.
nevertheless my general approach we be
1. understand the analysis brief completely including who will be the users
2. organise the data you provide. if the base data is to be aggregated from multiple sources, that we first need to done.
3. clean the data of type, format inconsistencies,
4. develop pivot tables to tease out trends/ patterns
5. look for specific correlations across parameters if required.
6. send to you for a first review
7. incorporate suggestions, graphs etc
