+Our rule of thumb is “one part research to two parts communication”. For a day spent doing interviews, for example, we expect to spend two days on analysis and synthesis, and sharing findings.
 
 In doing analysis and synthesis we want:
 
 * findings and next steps we can justify - as we are often challenged to explain why we have come to those conclusions
-* findings we can trace back to our research data - as we are often asked to show the evidence for our findings and where our ideas came from
+* findings we can trace back to our research data - so we can support our findings with anonymised quotes, clips, observations and numbers from our research data, and so we can reconsider and update our findings as we gather more data
 * to make analysis and synthesis a team sport - so our colleagues get involved and become advocates for our findings
 * a rational and repeatable process - as we do analysis regularly and need to do it efficiently

 Using this data effectively, and combining it with our other sources, can need significant skills in statistics and numerical analysis. So we may look for support from colleagues with specialist data analysis skills.

 With quantitative analysis, we always remember that numbers themselves are not findings. We work out what the numbers mean for us, and produce meaningful and relevant findings, supported by the numbers, that others can understand and act on.
