Online surveys - statement/questions and scoring validity

My company (that turns VIsion into Results through Leadership Execution) has several (5) diagnostic survey and reports covering Leadership Execution, Mindset, Teamwork and Competencies. The reports are targeted to the top tier organisations globally, thus validity of how the statement questions are presented and the reasoning (and supported research) for the statements along with the best scoring scale to be utlised is critical. Also how the results are articulated and presented is crucial and would cover: - Development of normative data (percentiles, distributions, etc) – overall and by industry/location etc - Factor (or reliability) analysis - Correlation analysis between statement and category items in the survey results and (separate to factor analysis) – eg if one overall category score is high how does this correlate to high/low other category scores etc. Bidders will have to supply credentials and evidence of deep experience in working on similar types of projects.
