Inter-expert negotiations – how to reach an agreement when every specialist defends their own truth
In project teams, we rarely argue about who is right "in general." Most often, everyone is right from their own perspective. The programmer says, "Without this test, the system will crash." Marketing responds, "Without the campaign, we will lose market share." Finance adds, "Without cost control, we won't survive the quarter."
These are classic inter-expert negotiations – conversations that are not about emotions or personal ambitions, but about different professional logics. Each expert defends their area, and the leader must find a way to reconcile these arguments.
Why inter-expert negotiations are so difficult
Experts use different languages. For one, "risk" means errors in the code, for another, it means loss of market share.
The arguments are often incomparable. How can you compare "5 days of testing" with "campaign deadline" or "savings of 200,000"?
Every expert has their own professional identity. Giving in is sometimes perceived as admitting that their area is less important.
The most common mistakes made by leaders
Attempting to arbitrarily resolve a dispute. Formally, a decision is made, but the expert whose opinion has been ignored later sabotages the project.
Forcing experts to discuss in one language. The result: chaos, misunderstanding, and growing tension.
Ignoring emotions. Even if the dispute seems "substantive," it is often about status and recognition in the background.
How to conduct inter-expert negotiations more effectively
Translate arguments into a common denominator. Instead of "this is important for IT" and "this is important for marketing," reduce both arguments to their impact on the project as a whole.
Use objective criteria. For example: impact on the customer, risk of delays, potential cost of error. This allows you to compare decisions within a framework of shared values.
Separate the person from the argument. An expert does not have to "lose" if their proposal is not accepted – it is important that they know that their perspective has been heard and taken into account.
Case study: a dispute in which everyone was right
In one of the teams, IT fought for longer testing, while marketing fought for the campaign launch date. The leader initially tried to make an arbitrary decision and "reconcile" both sides with half-measures. The result? Neither the testing was complete, nor did the campaign launch as planned.
Only a change in approach brought results. The team jointly assessed which criteria were key: the risk of error and the cost of delaying the campaign. It turned out that the launch could be postponed by two weeks, thereby reducing the risk of error by 70%. Both sides felt that their arguments had been taken into account.
Summary
Inter-expert negotiations are not a battle over who is right, but how to reconcile different points of view within a common goal. A leader who can create a common language and criteria not only resolves disputes, but also builds a culture in which experts feel that their knowledge matters.
