From the outside, a complex negotiation often looks like a continuous sequence of conversations leading toward an agreement. Viewed up close, however, it breaks down into phases that are very different in nature. Treating them all the same way, as though they were one long conversation, often comes at the expense of both time and the quality of the final outcome, even when each individual round appears to have gone well.
Haroldo Augusto Filho, an executive with experience in business negotiations and conflict management, notes that recognizing these distinct phases helps negotiators adopt the right approach at each stage, rather than maintaining the same posture from beginning to end in a process whose nature changes along the way.
The Recognition Phase, Before Any Concrete Proposal
At the beginning of a complex negotiation, before any numbers are put on the table, there is a phase of mutual recognition: the parties are still figuring out who the other side is, how willing each party truly is to negotiate, and what kind of relationship will sustain the discussions moving forward. Treating this phase as a waste of time and trying to jump straight into concrete proposals often undermines the stages that follow, even when moving quickly may initially seem like a way to improve efficiency.
In this context, Haroldo Augusto Filho points out that negotiators who genuinely invest time in this initial phase, without rushing to discuss numbers, tend to build a foundation of trust that significantly facilitates the proposal-exchange phase that follows.
The Proposal-Exchange Phase, Where Most of the Attention Is Focused
This is the most visible and widely discussed phase of negotiation: proposals and counterproposals, exchanged concessions, and attempts to test each side’s limits. It is also the most unstable phase, because every move by one party tends to trigger an immediate reaction from the other, requiring constant attention to the pace of the conversation and to how each proposal is received.

At this stage, rushed decisions tend to be more costly than at any other point in the process because the impact of each concession accumulates over several consecutive rounds, leaving little room for reconsideration afterward. This cumulative effect is why small mistakes in pacing during this phase often carry greater consequences than comparable mistakes made at other stages of the process.
The Final Package-Building Phase, Which Few Prepare for Carefully
Once the main issues have been discussed individually, there is a phase in which everything must be brought together into a coherent package, where clauses that appeared to have been resolved separately need to fit together without contradicting one another. This phase is often underestimated and treated as a formality when, in fact, it requires a level of attention comparable to the proposal-exchange phase, even though at first glance it may seem like an almost bureaucratic part of the process.
Haroldo Augusto Filho explains that internal inconsistencies in an agreement rarely arise from bad faith. In reality, they tend to result from issues that were negotiated separately without sufficient joint review during the final package-building stage. He considers this type of cross-review, in which each clause is compared against the others, to be one of the most frequently overlooked steps in the entire process.
The Formalization Phase, Where Precise Language Matters
The final phase transforms what has been agreed upon into precise contractual language, and it is at this stage that ambiguities overlooked during the discussions tend to emerge, usually in the form of a sentence that each party interprets in a slightly different way. Reviewing the final text together, rather than simply relying on each side’s memory of what was verbally agreed upon, helps prevent many of these differences in interpretation.
For Haroldo Augusto Filho, giving each of these phases the specific attention it requires, rather than applying the same pace and approach from beginning to end, is what distinguishes well-managed complex negotiations from those that reach the finish line with a technically concluded agreement but still contain unresolved issues that only become apparent after it has been signed.
