The 10–5–1 Cadence that Protects Service and Frees Cash

 

Synergies don’t evaporate due to a failed investment thesis. They die on the vine in the first eight weeks after close—quietly, expensively, and usually with everyone ‘busy.’ 

McKinsey reports that roughly 70 percent of mergers fail1, and if you’ve lived through a few add-ons, you know the pattern. The integration tracker is full. The weekly calls are packed. The deck says, ‘on track.’ But on the floor and in the numbers, the story is different: deliveries start slipping, expedite fees become normal, inventory swells ‘just to be safe,’ and AR aging drifts because no one wants to disrupt customers during integration. 

That’s not integration. That’s integration theater—and it’s how working capital gets trapped while value creation gets delayed. 

The fix isn’t a heavier-handed project management team. It’s operating control: lightweight management and execution discipline that forces weekly decisions tied to operational excellence and working capital. 

Here’s a playbook that works for Operating Partners and portfolio CEOs because it’s simple enough to run, but hard enough to hide from. 

The enemy: “Integration Theater” 

Integration theater is seductive because it feels safe. It produces activity (plans, trackers, updates) while avoiding the uncomfortable calls (what stops, what changes, who decides). 

It also delays real management until ‘systems are harmonized.’ Meanwhile, service variability increases, cash gets trapped, and the organization learns that integration is something you talk about—not something you run. 

If you want to avoid the Synergy Trap, treat integration like an operating system, not a project list. 

The early tool: the 10–5–1 Integration Control System 

You can explain this in one slide and run it in under an hour a week. That’s the point. 

10 metrics (weekly for the first 100 days): five that protect the customer and stabilize operations, and five that prevent cash from getting trapped. 

Service / OpEx (5): delivery or promise-date adherence, schedule attainment, a single quality signal (returns/complaints/scrap), throughput at the constraint, and labor productivity. 

Working capital (5): inventory days, excess & obsolete (E&O) exposure with a disposition plan, DSO with % AR >60 / >90, DPO with a blocked-invoice count, and a simple cash conversion view. 

5 weekly decisions (not updates): what changed, what’s red, and what we are doing differently next week. If you can’t name the decision, you don’t have a management operating system—you have reporting. 

1-page action list: the critical path only (typically 10–15 actions). Everything else goes to backlog. 

One practical rule: if an action can’t credibly move one of the 10 metrics in 30–60 days, it isn’t Wave 1. 

Start in diligence: build the first 30 days before Day 1 

Most integration ‘plans’ are written after close, when attention is fragmented and the business is already moving. That’s backwards. 

During diligence, you don’t need a 100-page binder. You need three outputs that make the first month executable: 

1) Baseline the 10 metrics (even imperfectly) so Day 1 isn’t guesswork. 

2) Set cash + service guardrails—what cannot break while you change things. 

3) Draft the first 10–15 actions tied directly to the metrics, with names next to them. If ownership is unclear in diligence, it won’t be clear after close. 

Lightweight governance that actually governs 

The goal isn’t more meetings. It’s a repeatable cadence that turns exceptions into decisions. 

Keep roles simple: one single-threaded integration lead running the cadence; metric owners across Ops, Supply Chain, and Finance; and a CEO/Operating Partner sponsor to clear obstacles and approve the hard tradeoffs. 

Run two rhythms: 

• Weekly (45 minutes): Exception Review. Review the 10 metrics, make the 5 decisions, update the 1-page action list. No narrative status. 
• Monthly (60 minutes): Value Review. Tie operational movement to a working capital bridge and asynergybridge—so ‘synergy’ is evidence-based, not aspirational. 

Non-negotiable rule: red requires a decision, not a discussion. 

Where to focus first: the 30–60–100-day sequence (OpEx + cash) 

Days 1–30: stabilize service and stop cash leakage. Protect OTIF/quality, identify the constraint, triage inventory (especially E&O), and run an AR sprint to clean disputes and fix invoicing. Don’t wait for an ERP project to start managing cash. 

Days 31–60: fix the mechanics that prevent relapse—planning parameters, lead times, reorder points, master data, and frontline operating routines that feed the weekly metrics. 

Days 61–100: standardize what worked and turn it into a module for the next add-on. This is how a roll-up gets faster with each acquisition instead of resetting every time. 

Key takeaways 

1) Kill integration theater early: fewer status reports, more actions and decisions. 

2) Run 10–5–1 weekly for the first 3 months: metrics, decisions, and a one-page critical path. 

3) Build the first month in diligence: baseline, guardrails, owners. 

4) Treat working capital + service level as your truth-tellers. They reveal whether integration is real long before the ‘synergy’ slide does. 

If management can’t tell—weekly—what changed in service and cash, and what decisions were made because of it, you don’t yet have operating control.
