Innovation Portfolio Review¶

Portfolio review routine — instantiates Opportunity-Gated Adaptive Diversification

A recurring governance review that checks whether resources are over-concentrated in one bet-horizon and rebalances the split across run-the-business, transition, and future-building work.

When an opportunity opens, the temptation is to keep every hand on the profitable core while the new space is colonised by someone else — or, in the opposite failure, to pour everything into speculation and starve the business that pays for it. Innovation Portfolio Review is the periodic governance look that watches the allocation of resources across horizons and pulls it back toward balance. Its defining move is that it judges the split of money, people, and attention, not the merits of any single branch: it asks "are we over-invested in one horizon?" and rebalances, leaving which variant wins to the selection mechanisms. It is the dial that gates diversification on opportunity from the resource side — opening the exploration budget when a space appears, and closing it back down once niches fill.

Example¶

A consumer-electronics firm runs the review quarterly. Every active program is tagged to a horizon: the flagship phone line (run-the-business), a handful of adjacent transition bets — a wearable, a home hub — and two speculative future plays on a newly opened sensor platform. The review measures the actual resource split and finds 92% of engineering hours sitting on the flagship, with the sensor-platform work notionally approved but effectively unstaffed. It also flags that one legacy program has quietly absorbed three teams that were meant to rotate onto transition work — a capture the org hadn't seen.

The output is a rebalanced allocation with teeth: a protected exploration budget floor for the transition and future horizons, a named cap on the legacy program's headcount, and the next review booked for the following quarter. Nothing here decides whether the wearable beats the home hub — that argument belongs elsewhere. What the review guarantees is that the newly opened opportunity actually gets funded to be explored instead of losing every quarter to the core by default.

How it works¶

Classify by horizon. Every active line is tagged run-the-business, transition, or future-building, so the portfolio can be seen as a split rather than a list.
Measure the actual split. Count the real resource commitment (people, budget, leadership attention) per horizon — not the intended one.
Compare to a target allocation and flag concentration. Hold the measured split against an intended balance, and surface any horizon or program that has captured a disproportionate share.
Reallocate and re-book. Move resources toward the target, set or refresh the exploration budget, and fix the date of the next review.

It operates on the resource ledger, deliberately upstream of and separate from picking winners.

Tuning parameters¶

Horizon bands — how many horizons and where the lines fall. More bands give finer control but more classification argument.
Target allocation — the intended split (e.g. a 70/20/10 run/transition/future stance). Setting it aggressively toward exploration accelerates diversification but raises near-term risk.
Rebalancing cadence — how often the review fires. Frequent reviews track a fast-opening space but invite churn and short-termism.
Concentration threshold — how skewed a share must get before it is flagged as capture. Tight thresholds catch drift early but generate noise.
Reallocation aggressiveness — hard caps and forced transfers versus gentle nudges. Harder moves correct faster but can whipsaw teams mid-stream.

When it helps, and when it misleads¶

Its strength is that it makes the exploration budget explicit and defended — the single thing most reliably raided when quarterly pressure mounts — and it catches slow resource capture that no single project decision would ever reveal. Framed against horizons, it keeps a firm from both future-starvation and present-bleed at once.^[1]

Its failure modes are procedural. Horizon classification is gameable — relabel a tired core project "transition" and the portfolio looks balanced while nothing has changed — so the review can drift into theatre. Its classic misuse is running it backwards: assembling the horizon chart after the budget is set, to ratify the spend that already happened rather than to challenge it. The discipline that guards against this is to fix the target allocation before seeing the current split, and to audit a sample of horizon tags rather than taking them on trust.

How it implements the components¶

Innovation Portfolio Review realises the resource-governance side of the archetype — the components that decide how much is spent exploring, not what is found:

exploration_budget — it sets, protects, and refreshes the resource envelope reserved for transition and future horizons.
rebalancing_cadence — the review is the recurring point at which the allocation is pulled back toward its target.
dominance_and_capture_monitor — it flags when one horizon or program has captured a disproportionate share of people, money, or attention.

It does not judge whether a niche is over-crowded (crowding_and_saturation_monitor — that's Saturation and Crowding Review) or decide which individual variants are kept or cut (selective_retention_rule — that's Multi-Criteria Selection Rubric and Merge and Deprecation Plan).

Instantiates: Opportunity-Gated Adaptive Diversification — this review is the resource-balance governor for the whole diversification cycle.
Consumes: performance evidence from Parallel Pilot Trials and the fit picture from Lineage–Niche Fit Dashboard, to know where reallocation would pay.

Notes¶

Three sibling "reviews" are easy to conflate. Innovation Portfolio Review governs the resource split across horizons; Saturation and Crowding Review watches whether a niche is over-populated; Preserve–Prune–Recombine Review decides the fate of individual variants. Keeping them separate is what lets a team rebalance the budget without re-litigating every branch, and vice versa.
