Our client, Managing Director of a Business Unit within a global group, had aligned with the Group CEO on four major ambitions:<\/p>\n\n\n\n
- \n
- Integrate the merged organisations into a\u00a0global specialist Business Unit<\/strong>, leader in its field<\/li>\n\n\n\n
- Catch up on integration delays<\/strong> caused by transaction complexity<\/li>\n\n\n\n
- Deliver significant\u00a0growth and synergies<\/strong><\/li>\n\n\n\n
- Contribute meaningfully to the Group\u2019s\u00a0sustainable transition ambitions<\/strong><\/li>\n<\/ul>\n\n\n\n
The human challenge was considerable:<\/p>\n\n\n\n
- \n
- Two former competitors<\/strong> brought together within one global company<\/li>\n\n\n\n
- A delayed integration process<\/strong><\/li>\n\n\n\n
- Very limited understanding <\/strong>of each other\u2019s operating models<\/li>\n\n\n\n
- Significant cultural differences<\/strong> with teams across five continents<\/li>\n\n\n\n
- A dynamic of mistrust <\/strong>starting to take root<\/li>\n<\/ul>\n\n\n\n
During interviews, leaders expressed both hope and fear:<\/p>\n\n\n\n
- \n
- \u201cWe could achieve so much together\u2026 but I worry the others won\u2019t really play the game.\u201d<\/li>\n\n\n\n
- \u201cAs the acquired entity, I\u2019m afraid we\u2019ll be absorbed \u2014 that decisions and opportunities will all be funnelled to the acquiring organisation.\u201d<\/li>\n<\/ul>\n\n\n\n
This is not an isolated case : 60\u201380% of mergers fail to deliver the promised value.<\/p>\n\n\n\n
We hope for 1+1 >> 2\u2026 but too often, we get 1+1 < 2.<\/p>\n\n\n\n
Beating the Odds Starts with the Human Factor<\/span><\/h2>\n\n\n\n
What this project confirmed \u2014 once again :\u00a0Successful post-merger integration starts with the human factor\u00a0<\/strong>\u2013 well before the org chart, the synergy targets, and the roadmap.<\/p>\n\n\n\n
In our experience,\u00a0five \u201cHuman How\u201d keys<\/strong>\u00a0are indispensable.<\/p>\n\n\n\n
- \n
- Stepping fully into the transition<\/strong>, and working through its operational and emotional impacts<\/li>\n\n\n\n
- Creating genuine\u00a0learning spaces with psychological safety<\/strong><\/li>\n\n\n\n
- Appreciating respective strengths, fostering\u00a0recognition and inclusion<\/strong><\/li>\n\n\n\n
- Practicing\u00a0openness and co-responsibility<\/strong>\u00a0in relationships<\/li>\n\n\n\n
- Being directive when necessary \u2014 and participative whenever possible<\/li>\n<\/ul>\n\n\n\n
These five keys are necessary – but not sufficient.<\/p>\n\n\n\n
Integration success also requires 5 keys on the business side:<\/strong><\/p>\n\n\n\n
- \n
- Thinking\u00a0outside-in<\/strong>, placing clients and stakeholders at the centre<\/li>\n\n\n\n
- Asking the synergy question:
\u201cWhat can we do together that we could not do apart?\u201d<\/strong><\/li>\n\n\n\n- Leading from the future-back by\u00a0co-creating a compelling shared vision<\/strong><\/li>\n\n\n\n
- Structuring a clear\u00a0integration roadmap<\/strong>\u00a0with defined workstreams<\/li>\n\n\n\n
- Ensuring teams truly have the\u00a0capacity to deliver<\/strong><\/li>\n<\/ul>\n\n\n\n
These 5+5 keys informed our approach for the six-month coaching journey with the new team, culminating in a 2.5-day seminar bringing together the 50 top leaders.<\/p>\n\n\n

The 5 + 5 keys for effective post-merger integration<\/figcaption><\/figure>\n<\/div>\n\n\n Our coaching was also grounded in our participative transformation approach, which made a very tangible difference in practice:<\/p>\n\n\n\n
- \n
- Define the strategic question that mobilises all stakeholders<\/li>\n\n\n\n
- Involve stakeholders and teams early<\/li>\n\n\n\n
- Facilitate the group to foster collective intelligence<\/li>\n\n\n\n
- Engage head, heart and values<\/li>\n\n\n\n
- Amplify what already works \u2014 AND address the real issues<\/li>\n\n\n\n
- Co-create an inspiring vision of the future<\/li>\n\n\n\n
- Combine impactful action with deep learning and unlearning<\/li>\n\n\n\n
- Elicit voluntary commitment for action<\/li>\n<\/ul>\n\n\n\n
\n
\u201cPeople don\u2019t resist change. They resist being changed.\u201d Peter Senge<\/p>\n<\/blockquote>\n\n\n\n
Our coaching approach<\/span><\/h2>\n\n\n\n
The overall project ambition was clear:<\/p>\n\n\n\n
\n
Together, create the conditions for success of our new integrated Business Unit \u2014 and achieve what we could not accomplish separately.<\/p>\n<\/blockquote>\n\n\n\n
We still needed to articulate the specific goals of the coaching. We clarified them with our client along two main lines:<\/p>\n\n\n\n
\u201cHuman How\u201d Goals for Integration<\/strong><\/h3>
\n- \n
- Getting to know one another<\/li>\n\n\n\n
- Strengthening relationships and trust<\/li>\n\n\n\n
- Taking stock of the transition and its impact on us<\/li>\n\n\n\n
- Taking ownership of our new identity and strategic vision<\/li>\n\n\n\n
- Developing our own capacity to lead this new identity and strategic vision<\/li>\n\n\n\n
- Preparing to embark our teams and stakeholders<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
Business (\u201cWhat\u201d) Goals for Integration<\/strong><\/h3>
\n- \n
- Understanding respective activities to build on our combined DNA at our best<\/li>\n\n\n\n
- Clarifying the new organisation<\/li>\n\n\n\n
- Co-creating a compelling shared vision<\/li>\n\n\n\n
- Building the operating model and action roadmap<\/li>\n\n\n\n
- Identifying and planning key integration workstreams<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
We then co-designed a structured, three-phase journey.<\/p>\n\n\n\n
Phase 1 \u2013 Initial Teaming with top team members across the 3 organisations<\/strong><\/strong><\/h3>
\n- \n
- Coaching sessions with the sponsor<\/li>\n\n\n\n
- Individual interviews with 15 representatives from 3 organisations<\/li>\n\n\n\n
- A 2-day integration seminar with the 15 representatives<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
Phase 2 \u2013 Developing the Shared Vision with the core team<\/strong><\/strong><\/h3>
\n- \n
- Five half-day sessions to co-create the shared vision with the\u00a0core team of 4 representatives<\/strong><\/li>\n\n\n\n
- Ongoing coaching sessions with the sponsor<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
Phase 3 \u2013 Engaging the Top 50 Leaders<\/strong><\/strong><\/h3>
\n- \n
- Half-day session with the newly formed executive team<\/li>\n\n\n\n
- A 2.5-day immersive seminar with the Top 50 leaders<\/li>\n\n\n\n
- Continued coaching sessions with the sponsor<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n
The Top 50 Leaders Seminar<\/span><\/h2>\n\n\n\n
The Top 50 Seminar was the culmination of the coaching journey.<\/p>\n\n\n\n
Our coaching challenge was to get the group on board and involved in the process, even though they had significant concerns and doubts about the integration. Right up until the dinner the night before the seminar started, some participants from the acquired organisation told me about their mistrust and fear of being the losers in the integration, of not having a say in the new company. <\/p>\n\n\n\n
\n
\u201cAs the acquired entity, I\u2019m afraid we\u2019ll be absorbed \u2014 that decisions and opportunities will all be funnelled to the acquiring organisation.\u201d Executive participating in the 50 Leaders workshop<\/p>\n<\/blockquote>\n\n\n\n
Creating safety and engagement required a carefully structured agenda and facilitation rooted in our participative transformation approach.<\/p>\n\n\n

Agenda of Top 50 Leaders Seminar<\/figcaption><\/figure>\n<\/div>\n\n\n This fostered a spirit of openness and engagement within the group throughout the three days.<\/p>\n\n\n\n
