Promotion vs Replacement Make the call that protects momentum
When a key seat underperforms, you have two levers: promote a known quantity or replace with outside leverage. Choose wrong and you pay twice—in time and trust.
Optimise for time to delta—not comfort or optics
This is not a referendum on kindness, loyalty, or brand. It is a question of how quickly the seat can produce the three outcomes that matter over the next 6–12 months: revenue, margin, ship speed, or risk reduction.
Promote proven adjacency. Replace for missing altitude.
Promote When
- The candidate has run a smaller version of the same machine with measurable deltas over at least two cycles.
- They can explain their work as Context → Constraint → Decision → Delta.
- Trust equity is high and the missing skill—cadence, dashboards, prioritisation—is rehearsable.
- You can install a coach and a clear 90-day operating contract.
Replace When
- The role’s deltas require decisions nobody on the current bench has made.
- An external operator can reach proof faster than an internal candidate can reach readiness.
- The culture needs a new centre of gravity: discipline, speed, or standards.
- The incoming leader can be paired with two trusted insiders as counterweights.
Plot altitude required against time to delta
Promote
Use known context and trust to capture speed.
Replace
Import decisions and systems the bench has never demonstrated.
Promote With a Charter
Define milestones, coaching, and proof windows.
Either—But Simulate
Run a 90-day simulation before committing the seat.
Price the decision before debating the person
Compare the first 6–12 months, including the gains and the hidden drag on each path.
All-in Promotion Cost
APC = comp uplift + coaching + error tax − trust dividend − context speedInternal context creates leverage, but only when the learning gap remains tolerable.
All-in Replacement Cost
ARC = search + premium + onboarding drag − decision altitude − system importExternal cost can be rational when new altitude compresses proof and imports durable mechanisms.
Test the role before awarding the title
Simulate the Role
Run a 60–90 minute case using real constraints, incomplete information, and reversible choices.
Reference Decisions
Ask previous colleagues: “Which decision of theirs still survives?”
Publish the Contract
Make deltas, cadence, dashboards, escalation triggers, and hiring authority explicit.
The 90-day transition playbook
Name Counterweights
Pair accelerators with a Stabilizer and risk-averse leaders with an Initiator.
Freeze Scope Creep
Keep the seat focused on the three deltas for 90 days.
Use Two Tracks
Weekly executive one-pager plus a live operator dashboard.
Write Thresholds
Reversible decisions at 70% information; irreversible ones escalated.
Review at 45 / 90
Run blameless post-mortems and grade decision flow, not personality.
Sharpen the hypothesis. Verify the behaviour.
BaZi offers a structural lens on default behaviour, decision tempo, risk appetite, and power style. It does not decide who earns the seat. Use it to improve the probe, then double-lock every conclusion with real evidence.
“Describe the largest system you built. What continued working after you stepped away?”
“Walk through a turnaround. Which lever moved first, and what was your rollback rule?”
“What norm did you reset in your last team, and what measurable behaviour changed?”
A respected internal operator was not yet ready for national altitude
A regional operations head was borderline for a national role. The team chose replacement, then paired the incoming leader with the internal candidate as Stabilizer and published decision rights on day one. The move protected trust while importing the missing altitude.
Two quarters later
The outcome justified the decision through operations, economics, and customer stability.
Avoid the expensive version of either choice
Sentimental Promotions
Buying peace today and paying in cash later.
Celebrity Replacements
Paying for brand and receiving theatre.
Ambiguous Handovers
Two people appear to own the same lever.
Scope Drift
The leader hides from the delta behind projects.
