Most managers are familiar with the principles of feedback. They know that constructive feedback must be factual, specific, and delivered at the right time. However, this knowledge alone is not enough to change practices. In most organizations, feedback remains rare, comes too late, or is phrased in such a watered-down way that it loses all practical value.
This shortcoming is not a methodological issue. It is a training issue. Feedback-based training does not simply convey more theoretical frameworks; it creates the conditions for learning through practice, using real-life situations and language that can be directly applied.
Each managerial style develops its own resistance to feedback. The analytical manager views emotions as irrelevant. The empathetic manager downplays difficulties to preserve the relationship. The visionary excels in group meetings but avoids one-on-one discussions. The efficient manager considers the process a waste of time.
These biases do not disappear simply by learning the methods. They are mitigated through repeated exposure to training scenarios that bring them to light. The NUMA feedback training program is specifically designed to build these sequences: identifying one’s own resistance, naming it, and developing concrete behavioral alternatives.
A common mistake among managers is to treat feedback as a single, homogeneous category. However, there are three distinct types of feedback, each with its own rationale, and confusing them reduces their effectiveness.
Reframing feedback addresses an urgent behavioral issue. It is given immediately, in private, and must be prompt. Delaying this type of feedback dilutes its impact and sends a mixed message to the entire team.
Developmental feedback is part of a medium-term growth strategy. It requires advance preparation, is based on observable and recent facts, and incorporates a forward-looking perspective. This is where precision becomes crucial: referring to behavior observed the previous week is much more credible than making a sweeping generalization like “you always do that.”
Appreciation-based feedback is the most overlooked type. A generic compliment does not constitute useful feedback. Effective appreciation-based feedback identifies the observed behavior, explains its impact on the team or the client, and indicates what the manager would like to see repeated. This specificity transforms a polite gesture into a tool for fostering genuine engagement.
For more information on how to implement these three approaches, see our article on feedback management.
The COIN method provides a structured framework that can be applied to all types of feedback. It breaks down feedback into four dimensions: Context (setting the scene at a specific moment), Observations (describing indisputable facts), Impact (explaining why it matters), and Next Steps (outlining concrete next steps).
Impact is the aspect that is most often overlooked. Without it, the recipient may acknowledge the feedback without fully grasping its true significance: “That’s just my style; that’s how I am.” Identifying the impact—whether it relates to customer relations, team dynamics, or personal development—is what transforms a comment into a catalyst for growth.
Mastery of this method cannot be achieved simply by reading about it. It is developed through practice using scenarios provided by the participants themselves, along with role-playing exercises and structured debriefing.
Training only has a lasting effect if it leads to simple routines. Without being integrated into daily life, good intentions fade away within a few weeks.
The feedback log is the core tool: a file updated for 15 minutes at the end of the week that records factual observations gathered during interactions. It helps prepare feedback with a level of precision that surprises employees and strengthens managerial credibility.
The Start-Stop-Continue method structures bilateral discussions between peers or with a manager. It identifies what is working in the working relationship, what could be introduced, and what should be changed. This format, prepared in advance and used at the end of a project or during an individual review, standardizes the exchange of feedback and extends its flow beyond the hierarchy.
To establish these rituals at the team level, check out our guide to a culture of feedback.
Participants leave with three practical takeaways: the ability to distinguish and articulate the three types of feedback in their respective contexts; COIN-based phrasing they’ve tested in their own team situations, which they can put to use immediately the following week; and a simple system of routines so that feedback no longer depends on a favorable opportunity, but rather on regular, intentional practice.
Giving useful feedback is not an innate ability. It is a managerial skill that can be learned, structured, and strengthened through repetition. NUMA’s Feedback Workshop supports managers and employees in this journey: from understanding the principles to developing a consistent, precise, and truly useful practice for their teams.
