Portfolio Balancing for Project Portfolios: Four Trade-Offs to Check

Portfolio balancing is the process of optimising the mix of portfolio components to further the organisation's strategic objectives. A portfolio component is a programme, a project or other work the organisation funds together.

The Project Management Institute (PMI) publishes the discipline's reference standard, The Standard for Portfolio Management, Fourth Edition (2017).

Balancing sits between ranking and approving. It comes after each item has been judged on its own merits, and asks whether the whole set is the right mix.

In our project portfolio management process, balancing is step 4 of seven, between selection and authorisation. It exists because a list can be right item by item and wrong as a mix.

A balanced project portfolio manages four trade-offs: risk against return, short-term against long-term goals, project types against the organisation's strategy, and limited resources across the portfolio.

Balancing works against criteria, a desired risk profile, performance metrics and capacity limits. Read that list as a requirement to decide the targets before the review, not during it.

In practice the four trade-offs become four questions:

• Risk and return: how much of the money sits in high-risk work?
• Time horizon: how much of it pays back soon, and how much later?
• Project type: how much goes to each strategic category your organisation uses?
• Resources: does committed demand for your scarcest skill fit the capacity you have?

A ranked list does not answer these. Funding the top-scoring items can leave a dependency unfunded, overload a scarce skill or concentrate risk, which our project prioritization framework treats as the step after ranking.

Four investor rules carry over: a target mix chosen in advance, a measure of drift, a calendar review and a tolerance band that triggers action. Selling the best performer does not carry over, because a project cannot be sold to restore the mix. Here, drift means the gap between the actual mix and the target mix.

Vanguard's rebalancing guidance, as retrieved 27 October 2026, describes three methods: calendar-based, threshold-based and a combination. Its example is a 70/30 portfolio rebalanced "when your allocation is off-target by 5 percentage points or more", and it says an annual rebalance is optimal for many investors, while monthly or quarterly rebalancing is too frequent (Vanguard, Rebalancing your portfolio).

A project portfolio has triggers an investor does not have: rebalancing is called for when the portfolio has deviated from strategy, when risk needs to be better balanced, and when strategic direction changes significantly. In this page, rebalancing means that reallocation, and balancing means the ongoing process of keeping the mix optimised.

Our recommendation: review on your governance calendar, but give every row a tolerance so a breach cannot wait for the next meeting.

A project has no market price, and stopping one costs money and credibility that a sale does not. The levers are therefore different from an investor's: suspend, reprioritise or terminate a component.

Our recommendation is to try the levers in order of cost:

1. Steer new intake to the under-weight band, so the mix corrects as new work is approved.
2. Reshape or re-phase a component, for example moving its later phase into the next funding cycle.
3. Pause a component whose benefit is lowest in the over-weight band.
4. Terminate only when the first three cannot restore the mix.

Our recommendation: if one scarce team is your bottleneck, test the resources row first, because a mix that looks balanced on paper cannot be delivered if that team is overcommitted.

Decision rules for what to do with a failing row (fund, reshape, pause, terminate, reclassify) are in our portfolio strategic alignment framework.

A drift check compares the actual share in each band with its target and flags any band outside tolerance. In the illustrative ₹80 crore portfolio below, near-term work is 57.5% against a 50% target, so that band is breached and ₹6 crore must move. A drift check is the horizon row of the balance check described in the next section.

First the investor arithmetic, as an illustration. A ₹10 lakh portfolio targets 60% in one holding and 40% in another. After a year the holdings are worth ₹7,20,000 and ₹3,60,000, a total of ₹10,80,000. The first holding is now 66.7% (7,20,000 ÷ 10,80,000). Restoring 60% means holding ₹6,48,000 (60% of ₹10,80,000), so ₹72,000 moves to the second holding.

Now the project version. These figures are invented to show the method. The targets and the ±5 percentage point tolerance are our model, not PMI figures.

Working: shares are actual ÷ ₹80 crore. Targets restated in rupees are ₹40 crore, ₹24 crore and ₹16 crore (50%, 30% and 20% of ₹80 crore). The moves are therefore ₹6 crore out of near-term work (46 − 40), ₹2 crore into medium (24 − 22) and ₹4 crore into long-term (16 − 12), and 2 + 4 = 6.

Read the table as a decision, not a verdict. The long-term band sits exactly on its limit, so any further drift breaches it. The first lever is to direct the next approvals to long-term work. Only if that cannot close the gap should near-term components be re-phased or paused.

A balance check covers five rows: risk, horizon, project type, resources and strategic direction. Each row passes when its measured value is inside a tolerance you fixed before the review, and fails otherwise. Fill in the target and tolerance columns first; copy the table into your own sheet.

How to run it:

1. Set targets and tolerances before the cycle begins, and record who owns each row.
2. Measure actuals from the portfolio as it stands, including work already authorised.
3. Take every failing row to the governance forum with a proposed lever from the order above.

For the risk row, remember that the risk to balance is often shared by several components at once. Our portfolio risk management guide shows how to find it.

If you balance portfolios professionally, the PMI Portfolio Management Professional (PfMP®) certification is the credential that tests this work, and our PfMP® Self-Paced Learning programme prepares candidates for it. The programme has nine modules, including Portfolio Strategic Management, Portfolio Governance and Portfolio Management Process, which cover the strategic alignment and governance side of the work this page describes.

The programme also includes 1,000+ exam-style practice questions and a PfMP® Application Guidelines module. As of October 2026 our course page lists it at US$549.

As of October 2026, our PfMP® Application Writing Support is US$199 and our PfMP® Fast Track Program is US$1100, both listed in the Course Store.
