Why You Need a Portfolio of GenAI Projects (With Business Cases to Match!)

Learn how to build a Generative AI portfolio and create strong business cases for AI investments. Discover strategies to maximize ROI, manage risks, and align AI projects with business goals.

By Steve Harris

Generative AI (GenAI) has the ability to transform industries, unlock efficiencies, and drive innovation - no doubt. Are organisations struggling to move beyond scattered experiments or uncoordinated deployments? The key is to treat GenAI projects like any other strategic investment - by building a portfolio and backing each initiative with a solid business case, while appreciating the difference that GenAI brings and the rapid evolution of the GenAI market.

What Is It?

A GenAI portfolio is a structured collection of GenAI projects, managed like a capital investment portfolio. It ensures GenAI initiatives align with business strategy, avoid duplication, allow risk to be managed and maximise returns.

A Business Case is the justification for a project. It outlines the problem, the GenAI solution, expected benefits, costs, risks, and success metrics. A well-crafted business case ensures that only the most valuable and feasible GenAI projects receive funding and resources.

Without a portfolio approach, GenAI initiatives often become disconnected experiments with uncertain ROI. Managing GenAI investments systematically helps businesses prioritise high-impact projects and scale GenAI effectively. Having said this, GenAI is a rapidly evolving technology and we must leave room for managed experimentation within the portfolio.

What Does It Mean From a Business Perspective?

Taking a portfolio and business case approach to GenAI projects delivers tangible business advantages (just like any portfolio approach):

  • Unclaimed Cost Savings : Many businesses underutilise GenAI’s potential to automate processes and reduce expenses. A structured portfolio ensures cost-saving opportunities are identified and acted upon.
  • Time Optimisation : GenAI driven efficiency gains often go untracked. A portfolio approach ensures savings are measured and leveraged for business growth.
  • Strategic Alignment : AI projects should serve business goals, not just be tech experiments. A portfolio ensures every GenAI initiative maps to business priorities.
  • Better Risk Management : GenAI projects come with risks, some are new (bias, compliance, security). A disciplined approach ensures risks are identified, understood and mitigated before deployment.
  • Maximise ROI : By prioritising GenAI investments based on potential value, businesses can focus on the highest-impact initiatives, maximising returns while still leaving room for experimentation.
  • Avoiding Redundancy : Without coordination, multiple teams may develop similar AI solutions in silos. A portfolio approach prevents wasted effort and cost.

What Do I Do With It?

If you’re ready to move beyond ad-hoc GenAI experimentation, here are concrete next steps:

  • Inventory Potential GenAI Projects : Identify areas where AI can drive value. Engage business units to source ideas - drive your portfolio from a road map (work with your EAO).
  • Develop a Business Case Template : Standardise how GenAI projects are evaluated. Include problem definition, expected benefits, costs, risks, and ROI calculations.
  • Establish a Cross-Functional AI Review Team : Ensure AI initiatives receive input from business, IT, compliance, and finance. This is where you can deal with the differences that this new technology brings - leave room for experimentation and have early off-ramps to allow for resource re-allocation.
  • Prioritise AI Investments : Score projects based on strategic fit, feasibility (this is important given the rapid pace of change), and expected ROI. Drop low-impact ideas early but leave room for experimentation with early off-ramps. Work with your investment committee to understand changes that GenAI project assessment drives.
  • Integrate AI Into Financial Planning : Treat GenAI like any other investment. Secure funding through structured capital allocation.
  • Monitor AI Performance and Outcomes : Track ROI, user adoption, and efficiency gains. Adjust the portfolio based on real-world results. The difference that GenAI brings is that we will need to adopt new measures for success - for e.g. consider implications of model drift and operational effort to correct.
  • Refine and Scale : Start small, measure success, and scale up high-performing GenAI initiatives while phasing out underperforming ones. Understand whether the project approach is different - pilot phase, continuous learning and feedback and what that means for your Waterfall, Agile or Hybrid methodologies (work with your PMO).

By implementing a GenAI portfolio with structured business cases, your organisation can transform GenAI from a buzzword into a strategic advantage. The future of GenAI success isn’t about running more pilots - it’s about making smarter investments.
