Promotion · High-potential · Succession
The leadership assessment built on decisions, not opinions.
Capsim's inbox simulations put each leader in a role and score how they actually decide under pressure, against a validated standard mapped to your competency model. You get objective readiness evidence at scale, so your promotion, high-potential, and succession decisions are grounded in real behavior, not guesswork.
Built with I-O psychologists. Trusted by global talent and L&D teams.
Scored from a role-based inbox simulation, against a validated standard
Illustrative example, not real data.
The difference
Manager ratings show one perspective. Observed decisions reveal what they miss.
Most readiness calls still rest on manager ratings, self-assessments, and calibration debates. Those signals are shaped by who's visible and who's liked. None of that shows how a person actually decides when the call is theirs and the answer isn't obvious. Capsim measures the decision itself, so readiness becomes evidence instead of opinion.
How it works
Don't ask how they'd lead. Watch them decide.
Capsim's leadership assessment is a validated inbox-simulation platform. Each leader works the decisions a bigger job demands, scored against your competency model, because how they decide is the clearest signal of whether they're ready to lead.
- Step into the role
Each leader works a realistic inbox of decisions: competing priorities, incomplete information, the calls a bigger role actually demands.
- Scored to a standard
Every decision is scored against an expert key built by I-O psychologists and mapped to your competency model. Validated, never AI-guessed.
- Measure at scale
Taken individually and online, usually about 30 minutes, so you can assess a whole population of leaders, not just a cohort in a room.
Run it inside a Leadership Accelerator cohort and the measurement goes deeper: live observer scoring, and decisions across a full simulation.
What you get
From one leader to the whole bench.
Each leader gets a readiness report: how they decided, where they're ready, and where they're still developing. Because every leader takes the same assessment, scored to the same standard, the reports roll up into a bench and succession view you can compare and defend.

One model, one standard, comparable across the slate.
Three ways to get one
Ready to run, or built around you.
Start from a proven library, author your own, or have Capsim build one to your roles, your scenarios, and your competency model.
Start from a proven library
A library of validated inbox simulations you can deploy now: general management, people management, decision-making, and more. Begin with a risk-free pilot.
Author it yourself
No-code authoring, often in hours. Take the real situations your leaders face, de-identify them, and turn them into a scored simulation.
Custom, built with you
We build the assessment to your roles, your scenarios, and your competency model, with your subject-matter experts. Typically a few weeks to a couple of months.
Proof
Validated. And it shows up in promotions.
Across a 398-person validation study, inbox-simulation scores correlated with supervisory performance ratings, the field-standard criterion, more strongly than traditional assessment centers (around .37). Built with I-O psychologists at DePaul University.
ReliabilityTest-retest reliability: the same leader scores consistently across sittings, so a readiness call holds up to scrutiny.

Microsoft assessed leaders before and after with Capsim's inbox simulations, then tracked who advanced, evidence of growth, not a satisfaction score.
Works with what you have
Adds the layer your talent data can't see.
Your performance reviews, 9-box, and assessments already tell you a lot: what people have delivered, how they're rated, where they sit. What none of them shows is how a person decides when the call is theirs. Capsim adds that judgment layer, scored to the same competency model. It's there to inform the decision, not to make it.
Your instruments stay
Keep your performance data, 9-box, and assessments. Capsim doesn't replace them, and it doesn't ask you to reconcile a second system.
The layer they can't see
Those signals show what someone delivered and how they're rated. Capsim adds how they actually decide under pressure, the one thing the others can't capture.
Into your reviews
Scored to the competency model you already use, so the evidence lands in the talent reviews and succession conversations you already run.
Questions
What talent leaders ask
How is the assessment scored?
Each leader's decisions in the inbox simulation are scored against an expert key built by I-O psychologists, and mapped to your competency model. The scoring is validated and consistent, never AI-generated.
Is it validated?
Yes. The inbox simulations are validated situational-judgment assessments. Scores predict on-the-job performance more accurately than traditional assessment centers (an r of about .43, versus roughly .37), with test-retest reliability of .86 to .93, built with I-O psychologists at DePaul University.

If manager ratings are biased, why validate against supervisory ratings?
Because they're the field-standard criterion, the same benchmark assessment centers are measured against, and the study design answers the circularity. One manager rating one leader is shaped by visibility and likability. The validation spanned 398 experienced professionals and their supervisors, and each skill score correlated far more strongly with its matching performance dimension (r = .30) than with unmatched ones (r = .12), a pattern a halo can't produce. In practice the score never rests on ratings anyway: organizations pair it with their own outcomes, like pre-and-post measurement and tracking who advances.
What does it actually measure?
Judgment: how a leader weighs incomplete information, cross-functional tradeoffs, and consequences when the call is theirs. It's captured as behavior, not a personality profile or a knowledge test.
How is this different from the Leadership Accelerator?
The Assessment is the scalable instrument: leaders take an inbox simulation individually to produce readiness evidence. The Leadership Accelerator is the facilitated cohort program where leaders build that judgment, and where the measurement goes deepest, adding live observer scoring and decisions across a full business simulation.
How long does it take, and how does it scale?
Inbox simulations adapt to your use case, and can be made as short or as long as you need. An average one runs about 30 minutes, and some custom builds are as short as 15 to 20. Each leader takes it individually and online, so you can assess a whole population of leaders, not just a cohort in a room.
Can you map it to our competency model?
Yes. We map the inbox simulation to your competency model, so each leader's score reads in the language your talent process already uses, the same competencies your reviews, 9-box, and succession planning are built on.
Does it replace our existing talent tools?
No. Your performance data, 9-box, and assessments stay. Capsim adds the one layer they can't see, how a leader actually decides under pressure, scored to the same model and dropped into the reviews you already run.
Should we base a hiring or promotion decision on the assessment alone?
No. No single assessment should be the sole basis for a hiring or promotion decision. Capsim gives you objective evidence of judgment to weigh alongside your other inputs, performance, experience, and interviews, so the call is better informed. The decision stays yours.
Do you use Comp-XM?
No. Comp-XM is our academic assurance-of-learning exam. Corporate readiness runs on the inbox simulation, plus the deeper observer and in-simulation measurement you add inside a Leadership Accelerator cohort.
Who is it for?
Identifying high-potentials, making promotion decisions with evidence behind them, and building a succession bench you can defend, before the role is real.
