[3/5] Executing AI Projects: From Concept to Reality with Agility

With a solid strategy and prepared data, it’s time to build your AI solution. Execution is often where AI projects stall or veer off-track, so a nimble, well-managed approach is key. Unlike routine software projects, AI development is experimental and requires flexibility. By assembling the right team and embracing iterative methods, you can turn your AI concept into a working reality that meets your business goals.

• Form a cross-functional team that brings together business experts, data scientists, and IT developers.
• ‍Adopt an agile approach: work in small sprints rather than a rigid long-term plan.
• ‍Start with a proof of concept (POC) to quickly validate the idea on a small scale.
• ‍Iteratively refine the solution: continuously test AI outputs and improve the solution.
• ‍Engage stakeholders frequently with demos and feedback to keep the project on track.

Building a Cross-Functional Team with an Agile Mindset

AI implementation works best with a diverse team. Include members from the business side (who understand the problem), data scientists or analysts (to develop the AI logic), and IT/developers (to integrate the AI into systems). This ensures you have the skills to tackle both the technical and business aspects of the project. Ensure everyone is aligned on the project’s objective so they share a common vision of success.  

Traditional waterfall project management can struggle with AI projects because there are many unknowns. It’s wiser to use an agile approach with short development cycles. Plan the work in sprints (e.g., 2 weeks each) where the team builds and tests something tangible at the end of each sprint. Agile methods allow you to adapt as you learn more about the data and what the AI can do, and invites continuous input from business experts throughout the process. This close collaboration ensures the solution stays relevant to business needs.

Starting Small: Proof of Concept First

Rather than trying to build the perfect AI system straight away, start with a proof of concept (POC). This is a basic, stripped-down version of the solution focusing on the core idea. The goal is to quickly prove that your approach is technically feasible and can deliver some value. For example, if your project is an AI to summarize customer emails, the POC might be a simple model that summarizes a limited set of email types with just a basic level of accuracy.

Building a POC quickly gives the team and stakeholders something concrete to evaluate and discuss. You can demonstrate early progress, which builds confidence. Importantly, it’s a learning opportunity: you might discover data issues or integration challenges, or refine your understanding of what users actually need. If the POC doesn’t work as hoped, it’s much better to learn that early when you can still change direction easily.

Iterative Development and Continuous Refinement

With an initial POC in hand, you can iterate to expand and improve the AI solution. In each sprint, add a bit more functionality or tweak the prompt to improve its performance. For example, after a basic email-summarizer POC, the next iterations could broaden the range of emails it handles and improve accuracy by fine-tuning the prompt or feeding it more training data. Keep changes manageable. It’s better to make steady, incremental progress than to attempt a huge jump and risk breaking what you’ve built.

Continuous testing is part of this refinement. As the AI gains more capabilities, test each update on real or simulated data to gauge improvements. Track key representative metrics (accuracy, response time, error rate, etc.) to see if changes are actually making the system better. Also keep the original success criteria in mind so improvements align with the desired business outcome. If an approach isn’t working (perhaps a certain model type isn’t yielding good results), be ready to pivot and try a different technique in the following sprint. Trial and error is normal in AI projects. Not every experiment will work out, so build in the freedom to adjust course.

Testing and Validating AI Performance

Testing an AI solution goes beyond checking that it runs, you need to measure its output quality and usefulness. Use a validation dataset or pilot run to see if the AI’s predictions or recommendations meet your success criteria. Again, track relevant metrics (like accuracy, error rate, or resolution time improvement) to quantify its performance. Also, ensure the AI works well in practice: for example, is it fast enough and are its outputs presented clearly for users? Pay attention to any systematic errors or biases at this stage and adjust the solution or data if needed. It's much better to catch and correct issues now than after a full launch.

Engaging Stakeholders and Incorporating Feedback

Throughout the execution phase, keep stakeholders in the loop. This includes the executive sponsor, end-user representatives, and other key parties. Schedule regular demos at the end of each major sprint or milestone to show what the AI can do so far. This transparency builds trust and invites early feedback. For example, business users might point out a needed tweak that you can incorporate in the next iteration. Act on feedback quickly so the final product truly meets user needs.

With a well-tested, fine-tuned AI solution in hand, you’re ready for the next step - deploying it in the real business environment.
