Workplace diversity: how people work, the forgotten lever of collective performance

When an organisation measures workplace diversity, it usually relies on familiar indicators: the gender split, the age pyramid, the representation of people with disabilities, the diversity of backgrounds and origins. Those dimensions are essential in fighting discrimination and building inclusion, but they do not account for all the diversity present in an organisation.

Another kind of diversity runs through every team without ever appearing on a dashboard: diversity in how people work. It shapes how we decide, cooperate, handle disagreement, approach the unfamiliar or contribute to a project. It belongs to each individual, whatever their age, job or background.

Those differences usually go unnoticed. Yet they explain a great deal of what actually happens inside a team, a leadership group or a project. Taking them into account widens the conversation about workplace diversity, and turns it into a lever for collective performance.

The diversity you cannot see: how people work

A CV tells you about a career. It says nothing about how someone works day to day. For example:

• How they decide: some decide quickly on instinct, others need to have explored several scenarios before committing.
• Their relationship to conflict: for some, disagreement is a thinking tool; for others, it puts the relationship at risk.
• Their need for structure or autonomy: some need a clear frame to give their best, others thrive on autonomy.
• Their preferred way of contributing: some like opening up new avenues, others going deeper, structuring, passing on knowledge or finishing.
• How they exist in a group: some speak up naturally in meetings, others prefer to contribute in writing, connect people, or work quietly and in depth.

Two engineers of the same age, from the same school, in similar roles, can work in radically different ways. That is precisely the dimension that escapes diversity policies built on visible criteria alone.

Why differences in how people work strengthen a team

These are not simple personality traits. They bear directly on a team's performance, at several levels.

They shape how a team decides, how it spontaneously divides up roles, and how it handles tension.

They also matter a great deal for engagement. When someone can never contribute through what naturally drives them, they usually end up disengaging — not for want of goodwill, but because they have been spending, over months, an energy that is not theirs.

That is often when misunderstandings appear. Left unexplained, differences in how people work are easily read as flaws. The person who analyses before deciding becomes "slow". The person who questions the frame is seen as "resistant to change". The person who says little in meetings is judged "not invested". Judgement takes the place of understanding.

Yet those same behaviours tell a completely different story in context: the person who takes their time makes decisions safer, the one who challenges the frame surfaces the blind spots, and the one who speaks rarely often brings more depth to the analysis.

Research backs the value of that diversity. Inclusive teams are up to 35% more productive, and the companies furthest along on diversity are 25 to 35% more likely to outperform their competitors financially (McKinsey, 2020). Boston Consulting Group, for its part, shows that the most diverse leadership teams innovate more (BCG, 2021). But those benefits do not follow automatically from diversity. They appear when differences genuinely become complementary.

The risk of teams that are too alike

A team whose members work in very similar ways often feels efficient. Conversation flows, decisions come quickly, disagreements stay limited. That comfort is real. It can also hide a fragility.

Sharing the same reflexes, a team develops the same blind spots. Decisions are challenged less, some project phases are systematically favoured while others are neglected. Innovation slows for lack of genuinely different perspectives. The team gravitates towards the work that suits its members' preferences, and risks leaving aside the work that calls for other kinds of contribution.

That sameness is rarely deliberate. It usually comes from a well-known bias: we tend to hire people whose way of working feels familiar. Conversation is easier, interactions more natural, and a sense of "fit" settles in quickly. Over time, that bias produces genuine mirror hiring. The leadership team gradually comes to resemble its leader. Its members share the same reflexes, favour the same kinds of decision, and risk neglecting the same dimensions of the work. The limit becomes especially visible when the company has to change course, weather a crisis or carry through a transformation.

From diversity to complementarity

Faced with that, the first instinct is often to diversify profiles. That is useful, and it is not enough.

Putting different people together does not, on its own, create value. At first it usually creates more friction. Two partners can be highly complementary on paper and fall into conflict quickly if each reads the other's way of working as a lack of rigour, commitment or responsiveness. The task is therefore to make those ways of working useful to shared goals.

That means first making them visible, then having a shared language to understand them. They can then be recognised as contributions rather than flaws, before being organised into a division of roles that fits what the project needs. Because the phases of a project do not call on the same talents. What an exploration period needs is not what a structuring or a rollout phase needs.

It is that step, from diversity to complementarity, that lets a team turn its differences into value.

Making ways of working visible: the Map & Match reading

One question remains: how do you actually make those differences visible? That is what the Map & Match approach is for.

Energy Skills™ bring out what naturally drives a person's contribution: the work that gives them energy over time when they do it. That reading completes the picture skills give, which tell you what someone can do without always saying what keeps them engaged.

Those drivers organise themselves around five major value-creating functions: initiating, delivering, enriching, steering and connecting.

From a questionnaire, each person receives a map of their talents. Reading them collectively then reveals how contributions are spread across the team, and shows its strengths, its imbalances, and the functions under-represented given what the organisation is trying to do.

The change of perspective matters. There is no longer a good or a bad profile — only complementarity between different people, in the service of a shared goal.

Making different profiles work together

Diversity in how people work already exists in every organisation. The task is therefore not necessarily to hire more diversity, but to learn to recognise the diversity already there and to organise complementarity better.

Each way of contributing answers a different need: creating momentum, deepening an analysis, making a decision safer, connecting people, or turning an idea into something real. None of those contributions ranks above the others. They perform when they are called on at the right moment, in the service of a shared objective.

Taking ways of working into account opens a complementary angle on workplace diversity. Collective performance depends far less on how alike profiles are than on the team's ability to cover everything its objectives require.
