Introduction
Many organisations still run their performance reviews using Google Sheets or Excel. While this method is familiar, it comes with significant drawbacks in follow-through, visibility, time efficiency, and data accuracy. When reviews are conducted only twice a year for example, the inefficiencies of a spreadsheet-based process compound — increasing the administrative workload, increasing the risk of errors, and further reducing the likelihood of follow-through on development actions. Prosper streamlines the process, providing automation, real-time tracking, and integrated follow-up to drive better cultural and operational outcomes.
Spreadsheet-Based Performance Review Workflow
Preparation Stage (per review cycle)
- Set Review Timeline – Define dates, milestones, and reminders for the cycle.
- Confirm Review Criteria – Establish categories and rating scales for performance and behaviours.
- Update Employee Master List – Ensure data is up to date for all employees.
- Assign Managers – Link employees to their managers in the master list.
- Template Setup – Create separate tabs for self-assessments, manager reviews, and dashboards.
Execution Stage (per review cycle)
- Distribute Self-Assessments – Share templates via Google Sheets or Excel.
- Manager Review Input – Managers complete reviews, often pulling data manually.
- Progress Tracking – Update status manually; slow to identify incomplete reviews.
- Mid-Process Reminders – Send multiple email chasers without automation.
- Lock Completed Sections – Protect ranges or cells to prevent edits after completion.
Post-Review Stage (per review cycle)
- Collate Data – Merge self and manager reviews into one consolidated file.
- Analysis & Insights – Create pivot tables/charts for trends and averages.
- Calibration Meetings – Align scoring across leaders.
- Finalise & Store – Lock and archive the final version.
- Communicate Outcomes – Conduct feedback meetings with employees.
- Follow-up Actions – Record in separate documents, which often go unchecked until the next review.
Negatives of Spreadsheet-Based Reviews (Twice-Yearly)
1. Administration & Time Cost
- HR workload – 40–60 hours annually for setup, chasing, and consolidation.
- Managers spend 4+ hours per employee per year on admin instead of meaningful coaching.
2. Data Accuracy & Risk
- Higher error rate from repeated data handling.
- Multiple file versions in circulation after each review.
- Security risks when sensitive information is emailed or stored without proper access controls.
3. Lack of Follow-Through
- Development plans set in mid-year reviews are often forgotten until the end of year.
- No prompts or tracking between reviews to ensure goals are progressing.
- Missed opportunities to adjust performance plans mid-cycle.
4. Visibility Issues
- Leaders cannot see progress or trends in real time.
- Delays between review completion and analysis prevent quick interventions.
- Comparing results across cycles requires extensive manual work.
5. Employee & Manager Experience
- Cumbersome process that disrupts workflow twice a year.
- No guided support or coaching prompts during review completion.
- Historical data from previous cycles is difficult to reference.
