Periodically, many organisations open a performance review cycle. Performance against objectives is assessed. Feedback from colleagues is gathered. The voice of the client is considered. And in more mature processes, someone whose position or experience provides a perspective that day-to-day work does not allow may also be involved.
All these perspectives help build a more complete picture. But there is one that often arrives less prepared: your own.
People frequently receive feedback but spend little time beforehand developing their own reflection.
Different perspectives. The same professional.
Organisations gather information about performance in very different ways. Some rely primarily on conversations with the direct manager. Others incorporate feedback from colleagues, clients, mentors or technical experts. Many combine several of these elements depending on the type of project or the organisation’s culture.
Each of these perspectives answers a different question.
The direct manager observes the results achieved and how they were achieved.
Colleagues provide insight into what it is like to work with you day to day.
The client reflects the impact perceived from outside.
And those involved in professional development, where these roles exist, help interpret progress over time.
But there is one perspective that is not always explored with the same depth: your own.
The data that makes it difficult to ignore
Research into professional assessment has produced a consistent finding.
78% of professionals taking part in 360-degree feedback processes rate themselves more highly than their colleagues and managers rate them.
Often, this is an information problem.
After working with more than 5,000 participants, Tasha Eurich reached an uncomfortable conclusion: 95% of people believe they are self-aware. Only 10–15% actually meet the criteria for self-awareness. What matters most in a professional context is that internal self-awareness — knowing yourself — and external self-awareness — understanding how others see you — are independent. It is possible to be strong in one and have a structural blind spot in the other.
The gap between how others see you and how you see yourself is exactly where development begins.
Why asking ‘why’ does not work
Building a useful reflection on your own performance requires two things: introspection and method.
When we ask ourselves why something did not turn out as expected, we tend to activate mechanisms of justification. We look for explanations that protect the image we have of ourselves. Eurich’s research documents this precisely: asking ‘why’ tends to produce rationalisations rather than clarity.
What works is asking ‘what’.
Not Why didn’t I achieve the result? but What did I do differently in the projects where I did achieve it? Not Why is this professional relationship difficult? but What could I do differently next time?
The difference lies in where each question points: one looks for an explanation; the other looks for action.
Self-assessment as a professional development tool
The following questions can help you prepare for a performance review or feedback conversation, or provide a way to contrast your own assessment with the feedback you receive afterwards.
- On actual results: What have I delivered this half-year that had an impact beyond simply completing the assignment? Is there anything I left unfinished that I could have resolved with better judgement and less haste?
- On technical development: Have I learnt something new that I am already applying, or have I accumulated knowledge that I still do not use? Is there a technical gap that I am avoiding acknowledging?
- On how I work with others: How do I contribute to the work of the people I collaborate with? Is there a professional relationship that I am managing poorly or avoiding?
- On autonomy and judgement: In which situations do I take a position of my own? In which do I wait for someone else to decide? Have I ever backed down from a position I disagreed with because doing so was easier?
- On the next six months: What do I want to be able to do six months from now that I cannot do well today? What do I need to stop doing for that to happen?
What changes when perspectives are compared
When external feedback is compared with prior personal reflection, the conversation tends to become more useful. Not because there is another form to complete, but because the comparison helps identify where the two perspectives align and where blind spots emerge.
Korn Ferry, analysing almost 100 million leadership assessments, found that professionals who overestimate their capabilities are 6.2 times more likely to derail in their careers. Not because they are technically worse. Because they do not have enough information about themselves to correct course in time.
The value does not lie in choosing between your own perspective and that of others. It lies in comparing them to turn feedback into a genuine opportunity for development.
No performance review process can do the work of personal reflection on behalf of each professional. Preparing for that conversation does not change the feedback you will receive, but it can change how you interpret it and turn it into an opportunity for development.
To finish: a practical proposal
The next time you have a performance review, development or feedback conversation with your manager — whether as part of a formal process or at the end of a project — do not arrive without having reflected beforehand. Answer these questions in writing and use them to prepare for the conversation.
Then compare that reflection with the feedback you receive. Where they align, you will find strengths worth consolidating. Where they diverge, you will probably find the work that can help you grow the most.
That gap, when seen clearly, is the most honest starting point there is. In that difference often lies the most valuable roadmap for continuing to grow as a professional.
Frequently asked questions about self-assessment and professional feedback
What is professional self-assessment?
Professional self-assessment is a structured reflection on your own results, capabilities, ways of working and areas for development. It becomes more useful when compared with feedback from managers, colleagues, clients or other professionals.
How should you prepare for a performance review?
It is useful to review your results, technical development, how you work with others, your level of autonomy and your development objectives beforehand. Arriving with your own reflection allows you to compare it with the feedback you receive.
Why is it important to compare self-assessment with feedback from others?
Because your own perception and the way others perceive you may not coincide. Comparing the two helps identify shared strengths and potential blind spots that a single perspective may not reveal.
What questions help with professional self-assessment?
Questions focused on facts and actions are particularly useful: what results have been achieved, what has been learnt, what could be done differently and what should change over the coming months.
