- What fund design can tell you—and what it cannotWhat fund-design diagnostics can reveal about a plan, why they do not forecast returns, and how to use the findings in an investment-team discussion.
- Should you model your fund forward or check the one you haveA model projects from assumptions. A construction check reviews whether a fund’s declared plans fit together. See why a firm may need both.
- When your fund stops looking like the one you raisedConfiguration drift is the gap between a recorded fund plan and current practice. Keep inputs current and changes clear for the team and LPs.
- What can you still change after the fund closes?After a fund closes, review what its terms fix, which decisions remain open, and how current experience can improve the next fund’s design.
How to read this pillar
Discipline here means consistency rather than caution. A Conviction-stage firm running a concentrated portfolio at high ownership is exercising construction discipline exactly as much as a Continuity-stage firm running a broad portfolio at moderate ownership, provided that in each case the rest of the configuration supports the choice. The three lifecycle stages occupy different frontiers, and the model does not treat a newer firm as a weaker one. What it looks for is contradiction: a fund declaring a portfolio count, an ownership target, and a fund size that cannot all hold at once is describing a construction that cannot be executed as written.
The same set of decisions is read by three engines, each asking a different question about it. Portfolio Efficiency and Firm Design Congruence assess the configuration recorded for each fund, and Cross-Fund Concentration across every fund the firm runs, with the Architecture Score integrating the three.
The model evaluates how a fund is built, not how it will perform. Its core scores do not certify investment quality or forecast returns. The separate Scenario Engine offers follow-on decision support for the GP to review. A construction the model reads as coherent can still return poorly, and one that surfaces tensions can still return well. Market timing, team dynamics, and deal access sit outside what a configuration can express. The reading is an instrument that supports judgment rather than a substitute for it.
