Functional Integration

Agree with the above comment, best way is to set up a common goal where the focus is on how to achieve it together. This should mean that the system, functions and processes that best help to meet the organizational goals will naturally fall into place. Often we find that the cultural differences actually become strengths because there are different perspectives in play to aid in problem solving.

I agree with the earlier comments about aligning on goals and using cultural differences as strengths. An approach I’ve found effective is to openly acknowledge the differences intentionally—rather than trying to smooth them over or assume they’ll resolve themselves. When two organizations come together, especially from different cultural backgrounds, it’s important to create space for honest conversations about how each team works, communicates, and makes decisions. This can be done formally through facilitated workshops or integration planning sessions where teams share their norms, expectations, and even frustrations.

From there, co-creating “ground rules” for collaboration and common goals and expectations for the behaviours expected going forward. These aren’t rigid policies, but shared agreements on how meetings are run, how feedback is given, how decisions are made, and how conflict is handled. It’s a way to build a new culture together, rather than imposing one over the other. This kind of intentional dialogue helps people feel heard, meets others where they are at and prevents misunderstandings. I feel like it also signals strong leadership values and inclusion to build a cohesive team—not just merging systems and structures.

One way we attempt to avoid confusion and to tackle possible issues around different cultures is by simply ensuring that we have workstream lead pairs for each workstream (one from the acquiring company and one from the acquired company) and they are jointly responsible for developing the integration plan (based on playbooks and previous examples). Each workstream should be feel ownership of that plan and be able to clearly explain it and provide updates in stand ups. Where different regions exist we may then break that function down into separate workstreams per region, for example People Ops – India and People Ops – USA.

We then also utilise change champions in all functions and locations who feed back whether the changes being communicated are clear and understood and are landing well or need to be adapted.

Cross-functional collaboration is essential to avoid confusion during the integration process, especially when different cultures are involved. Clear and timely communication, transparency, and sharing information about stages, progress, challenges, and successes make a significant difference. But this only works when the communications team collaborates closely with top management and HR from both companies. Leadership sets the overall direction, the communications team ensures messages are delivered clearly and consistently, and HR brings deep insight into experts, key talent, and the strategies needed to retain them.

When these three areas work together, cultural clashes soften, and people feel guided through change rather than having integration imposed on them.
