360° Feedback Software: Reveal the Real Blind Spots
What neither the annual review nor the engagement survey tells you about your employees and managers.
The annual review evaluates upward. The engagement survey measures the collective. Neither gives a complete picture of actual behaviour, whether for an employee, a manager, or an executive.
360° feedback fills this blind spot. Zest structures the campaign, guarantees the confidentiality of responses, and delivers results directly to the people concerned, with no intermediary.
A single point of view on an employee is a judgement, not an evaluation.
Most companies already collect signals about their employees and managers: annual reviews, engagement surveys, informal feedback. The problem isn’t a lack of information. It’s that this information fails to produce a complete picture, one that the person who needs it most can actually use.
The annual review frames the hierarchical relationship. The engagement survey captures the collective voice. But neither tells an employee how they are truly perceived by those who work with them, under them, or alongside them.
This is especially critical for managers, whose posture and style are only fully revealed through the eyes of those who work with them day to day. But this blind spot isn’t limited to managers: high potential and fast track employees benefit just as much from it.
360° feedback, or 360° assessment, creates this structured space. Zest manages this process end to end, from campaign creation to results delivery, within a framework that guarantees anonymity and encourages honest responses.
What does Zest actually do?
Set up your campaign
A manually run 360° feedback process exposes you to predictable problems: confidentiality that’s hard to guarantee, time consuming follow ups, and inconsistent data that’s difficult to work with. Zest centralises the entire process, from setup to results delivery, with no break in the user experience.
The campaign is split into two stages: a self assessment stage completed by the beneficiary, followed by a feedback collection stage from contributors. It can target a single employee, a group of managers, or an entire department. Zest allows you to configure simultaneous campaigns across multiple scopes.
Two formats, 360° or 180° feedback, depending on your organisation’s level of maturity
180° Feedback
Gathers perceptions from the direct manager and immediate team members.
Ideal for a first rollout
360° Feedback
Widens the circle to peers and internal clients, for a complete picture of the employee’s impact on their environment.
The Zest Lab, made up of occupational psychologists and HR experts, has designed scientifically validated questionnaire templates. You start from a rigorous foundation, one that can be adapted to your internal framework, your current priorities, and your target populations.
Select contributors and guarantee anonymity
Contributors
The quality of the feedback depends directly on how close the contributors are to the employee. Contacts who interact with the beneficiary regularly are more valuable than distant relationships. Zest doesn’t limit the number of contributors and lets you invite as many as needed.
Anonymity
Anonymity is guaranteed technically, not just by policy. A minimum number of contributors is required so that individual responses can never be identified in the reports. Without this genuine guarantee, contributors self censor, and censored responses produce a report with no value.
By default, the direct manager and the employees they supervise are included in the campaign. The beneficiary can also suggest additional contributors, within a framework defined by HR, for example colleagues or staff they have worked with on cross functional projects.
360° feedback improves the quality of your HR decisions
The results compare what the beneficiary believes they project with what their professional circle actually perceives. The self assessment is set against contributor feedback, source by source.
The built in AI analyses open ended comments: it automatically categorises themes and flags sensitive comments. The beneficiary receives a clear, readable summary, not a spreadsheet of raw data.
HR and the direct manager have access to a consolidated view of results across their scope, which can be exported for People Reviews and development committees.
Three use cases you can activate right away
Developing managers
This is the core use case. Gather feedback from peers, the direct manager, and direct reports to identify strengths and areas for growth, then feed this into an individual development plan.
Supporting a new role
The first few months are often the most critical and the least documented. 360° feedback allows you to gather targeted feedback quickly, identifying strengths to build on before difficulties take hold.
Informing an internal mobility decision
Bring together multiple perspectives to support a promotion or role change decision, and adjust the accompanying support accordingly.
What sets Zest apart from a generic feedback tool?
Built on science, not intuition
Questionnaires are designed with psychometricians and occupational psychologists.
Results are measurable, comparable over time, and defensible in front of an executive committee.
Anonymity guarantee
The guarantee is structural, not just stated.
This is what makes the difference between feedback that employees fill in honestly and a form that no one really dares to complete truthfully.
Two levels of depth suited to your maturity level
180° feedback to get started, 360° to go further.
Zest adapts to your stage of deployment, without forcing unnecessary complexity too soon.

Expert support included
Every client is supported by a Customer Success Manager specialised in HR. Campaign scoping, data analysis, actionable recommendations.
360° feedback improves the quality of your HR decisions
The manager employee relationship is a major driver of engagement. Zest’s BaromEX identifies the relationship with the manager as one of four key drivers of excellence for retaining the most engaged talent. Yet in most companies, this relationship is only assessed through a top down hierarchical lens.
Multi source feedback fundamentally changes the nature of the information available. Mobility, promotion, development plans: these are all decisions that used to rely on partial impressions, and that can now be based on cross referenced data, built from multiple independent perspectives.
Q&A
Frequently asked questions about Zest’s 360° feedback software
What is the difference between 180° Feedback and 360° Feedback?
180° Feedback gathers perceptions from the direct manager and immediate team members. 360° Feedback widens the circle to peers and internal clients, for a complete picture of the employee’s impact on their environment. Zest offers both levels: you choose based on your organisation’s maturity and the campaign’s objective.
Is 360° feedback an evaluation or a development tool?
It’s a development approach, not a performance evaluation. Results are shared with the employee to help build their development path, not to inform a compensation decision. This separation is a core design principle at Zest.
Is respondent anonymity really guaranteed?
Zest guarantees anonymity technically, not just by policy. A minimum number of contributors is required so that individual responses remain unidentifiable in the reports. Without reaching this threshold, no results can be shared. This mechanism is what gives contributors the freedom to respond honestly.
Who can be the beneficiary of 360° feedback?
This process is primarily designed for managers, whose posture is only fully revealed through the eyes of those who work with them. It can also benefit high potential or fast track employees, giving them a structured view of their impact. The campaign can target a single employee, a group, or an entire department.
How long does it take to roll out a first campaign?
On average, allow 21 days from signature to the first usable result. Native integrations with major HRIS platforms eliminate manual data entry and remove the need to involve IT.
Can we use our own questionnaire?
Yes. The Zest Lab’s template library is a starting point, not a constraint. You can build an entirely custom questionnaire based on your internal framework, or combine your own questions with those provided by Zest.
Does Zest integrate with our existing HRIS?
Zest has native connectors with the leading HRIS platforms on the market (ADP, Talentsoft, SAP SuccessFactors, and others). Employee data is synchronised automatically, with no manual re entry and no involvement needed from IT.
