Pet Projects: How Executive ‘Great Ideas’ Destroy Portfolio Value

Illustration of a unicorn-hippo creature representing pet projects

Many inspirational growth stories start with a paradigm shifting project: Netflix turning entertainment into a subscription model, Under Armour and connected data, Apple and iPhone... but for every free-thinking Unicorn story there are hundreds of portfolios littered with ugly Pet Projects, which start as one exec's "great idea" but turn out to be hungry hippos that eat all the resources and trample on your career.

Pet projects aren’t just quirky executive distractions — they are a major driver of portfolio overload, wasted spend, and strategic drift. They quietly erode value long before anyone notices.

Across hundreds of portfolios we've analyzed, pet projects show up in almost every organization — and they almost always drain more value than they deliver.

If this sounds familiar — critical maintenance keeps slipping, teams are permanently “at capacity,” and yet there’s always room for one more executive side-project — you’re already living with pet projects.

It is these Pet Projects that are most often to blame when it comes to waste within a portfolio. The PMI estimates that 20% of a portfolio is waste.

And in most cases, pet projects are the hidden source of that waste — consuming scarce capacity that should be delivering strategic value.

The hard part isn’t spotting a pet project — it’s challenging it in a way that protects relationships and still protects the portfolio.

Who better to speak truth to power than Amanda Oakenfull? As a specialist in portfolio turnaround she's seen the damage a rogue pet project can cause, and provides a direct simple view on how to deal with them:

Amanda’s experience highlights how common — and costly — pet projects can be. Here’s how to recognise them and stop them early.

In most organizations today, portfolios are already overloaded and resources are stretched thin. When an executive-driven pet project jumps the queue, something valuable is pushed out — often something critical. This is why tackling pet projects is essential to improving flow and delivering strategy.

What are Pet Projects?

Firstly let's be clear: Pet Projects are not cute. They are a pest within your portfolio that will destroy value and take your career with it.

They consume scarce resources but deliver little value. They distract the organization from what actually matters and quietly reduce the overall value your portfolio delivers.

At its worst, it can mean ignoring the basic requirements needed to keep your organization viable — the portfolio equivalent of fiddling while Rome burns.

Where do Pet Projects come from?

  • Chasing the latest shiny new thing: Beware the executive who has been to a conference. Or the CEO who thinks that all the other CEOs have a new toy...
  • Misplaced innovation: There is a pressure on leaders to be innovative thinkers, but many are simply not very good at it. Sadly, nobody has told them that.
  • Business cases are easy to manipulate: It's really easy to produce a business case that looks good with a little creativity in excel and PowerPoint, especially if there's no culture of accountability.
  • Weak prioritization process: If you don't have a proper process for project prioritization, then you can easily miss a pet, especially if you have a culture where "no" is a career limiting choice.
  • Fixation on delivery: If your PMO is overly focused on delivery and the detail of execution then it's very easy to miss the basic reality that they're working on a pointless project. Don't be that PMO who is delivering something useless, really well.

How to control Pet Projects

There’s no mystery here — stopping pet projects means changing how ideas enter the system, how they’re evaluated, and how trade-offs are made.

  • Broaden ideation: If ideas for projects only come from the top-down you're gong to end up with some pretty ugly pets. Why? Execs are, to put it bluntly, not the best people to come up with new ideas. The most successful initiatives come from the people close to the action, so why not source your backlog more inclusively?
  • Value-based prioritization: This is critical - define what matters to the organization to drive project selection. This will quickly highlight low value projects, and create an objective framework for telling the CEO that his bright idea is not the best use of company resources. The key is that you create a process where prioritization actively rules out pet projects in favor of better ideas.
  • Select projects as an organization not an individual: Projects belong to an organization, not to the person who happens to be the current custodian of a budget; therefore make sure that the organization is picking projects. This means having groups scoring projects, rather than an individuals mandating them.
  • Manage budget via multiple portfolios: A favorite bear trap in project selection is to ignore projects dedicated to maintenance, risk mitigation, and efficiency in favor of bigger shinier 'transformation' initiatives. To resolve, simply split the portfolio into 'buckets' that ringfence resource to ensure that a proportion of spend is always aligned to the less sexy investments.
  • Track value delivery: you need a culture of tracking value through the lifecycle of a project so you can respond if your good project morphs into a pet. People get attached to 'their' project so need to know that it's OK to put their hand up and say, "hey - this isn't a good idea anymore, let's stop".
  • Learn from mistakes: How many underwhelming projects have you seen delivered that get quietly swept under the carpet? They're embarrassing, but they're also a golden opportunity to learn from your mistakes.

Prioritization Matrix: Pet Project Killer

This simple graphic is all you need to get rid of pet projects. We've seen it time and again: show a leader data that says their project is a drag on their strategy, and they'll kill it. After all what they're trying to achieve is more important than how they do it.

The key is how you build it. If you have a good prioritization process then you're set, because you have a definition of value which works. Moreover, not only do you have great data, you also build buy-in through the process of collecting it.

This means that the bright idea from the boss is exposed as, objectively speaking, poor use of organization resources, and so needs to be rejected.

How to challenge a pet project without getting fired

The goal isn’t to tell a senior leader they’re wrong. The goal is to show, using the criteria they agreed to, that there’s a better use of scarce resources. These conversations become far easier when framed around value, not opinion.

Here are three phrases that work:

  • “When we score this against the criteria we agreed, it falls low on both impact and strategic fit…”
  • “If we fund this, here’s what gets delayed or dropped from the portfolio — is that trade-off acceptable?”
  • “If this is now a higher priority, should we revisit the full portfolio instead of making a one-off exception?”

You’re not blocking their idea. You’re protecting their strategy.

Once you can speak to value clearly, the next step is building a prioritization framework that consistently prevents pet projects from slipping through.
