Compare manager and self-evaluation scores including difference in Performance

Context / Problem: With a manager + employee evaluation form, both the manager and the employee score the same competences. Afterwards there's no easy way to see where the two assessments differ. That comparison is the basis for the review conversation ("here we saw it differently"). Desired solution: - Combine the manager's score and the employee's self-evaluation score an indicate the difference - Show a overview to see a total score for each competency (section) for both, with the maximum possible score and the difference - Quickly spot the questions or competencies with the largest gap, e.g. through highlighting or sorting by difference Current behavior: - Manager and employee answers are collected, but results are not shown as a structured comparison - Totals per competency and the differences between manager and employee aren't calculated - To prepare the review, managers export the answers or keep a separate spreadsheet that calculates totals and differences Impact: - Extra manual work for managers before every review - Risk of calculation errors and inconsistent preparation between managers - Less value from the self-evaluation, because the gaps worth discussing aren't visible right away - Some customers keep a spreadsheet alongside the platform, which makes the performance module less of a single source of truth
