Fund Streams, Not Projects: Portfolio Lean and Product Thinking

Halfway through the quarter, Finance froze hiring to “protect the budget”; the decision hit a critical product just as usage was spiking. Work piled up in analysis; support tickets climbed; the releases slipped. The teams were not broken; the stream was. Funding lived in project silos with start–stop approvals; the money did not follow the flow of customer value. While the teams can still continue executed; they can't fix the attrition gaps or "fund projects" behavior of the organization. It’s all too common.

What.

Value-stream funding treats the product as a long-lived system that converts capacity into outcomes, not a one-off project to be started and stopped. 

We define 3–5 value streams by customer or outcome; give each a stable budget; and govern with lean guardrails rather than heavy stage gates. Guardrails include explicit portfolio WIP limits, small batch commitments, spend bands, risk thresholds, and a rolling-wave review cadence that inspects learning and outcomes monthly while resetting targets quarterly. 

Use Throughput Accountingtechniques to see contribution per unit of capacity; elevate decisions from “what did we spend” to “what did the stream learn and deliver”.

So What?

Projects start, but routinely outpace their finishes (organizational ADD); context switching burns capacity; teams wait for money while partially started work ages in queues. 

This is local optimization in portfolio clothing. When you fund projects, you create stop–go friction and governance theater; predictability suffers. When you fund streams, you reduce transaction costs, align incentives to outcomes, and make it easier to steer based on real demand and learning.

Now What?

  • Name the streams: 3–5 product or customer-facing value streams; avoid departmental labels.

  • Set guardrails: portfolio WIP limit; spend bands per stream; risk thresholds; simple entry and exit criteria for bets.

  • Adopt rolling reviews: monthly check-ins for learning and capacity balance; quarterly outcome resets tied to OKRs or north-star metrics.

  • Visualize capacity vs demand: a portfolio Kanban that shows arrivals, WIP, and finished value per stream; highlight decision latency and blocked bets.

  • Measure contribution, not activity: simple Throughput Accounting view; finished value per time; operating expense as a guardrail; inventory as aged WIP.

  • Change leadership practices: build Kotter-style coalitions to unblock policy bottlenecks; apply Hamel’s human-centric principles to strip out approvals that add no learning.

Let's Do This!

Fund the stream; let teams flow; outcomes will then follow. When money, governance, and learning move together, you finish more of the right work with less thrash; predictability rises; customers feel progress sooner. 

Portfolio agility is not more projects; it is fewer, finished bets flowing through stable teams with clear guardrails and a cadence that rewards learning. Finance has to be a huge part of that, but often they don't know how. Let's teach them!
