Quality during Design

Dianna Deeney

Quality during Design is the podcast for engineers and product developers navigating the messy front end of product development. Each episode gives you practical quality and reliability tools you can use during the design phase — so your team catches problems early, avoids costly rework, and ships products people can depend on. You'll hear solo episodes on early-stage clarity, risk-based decision-making, and quality thinking, along with conversations with cross-functional experts in the series A Chat with Cross-Functional Experts. If you want to design products people love for less time, less cost, and a whole lot fewer headaches — this is your place. Hosted by Dianna Deeney, consultant, coach, and author of Pierce the Design Fog. Subscribe on Substack for monthly guides, templates, and Q&A.

    Shannon Cummings on Why Marketing Should Be in the Room Before the First Prototype (A Chat with Cross-Functional Experts)

    Your team keeps building the wrong thing, despite great effort. What if the problem isn’t execution. It’s the fog you’re navigating in? We speak with Shannon Cummings, a seasoned product and marketing strategist who’s spent his career bridging the gap between Marketing, Product, and Engineering. He’s launched life-changing medical devices, cut development time in half, and done it all by bringing marketing into the room before the first prototype.  In this episode: • Why product development fails when marketing is an afterthought • How early customer insight—not prototypes—should drive design • The real power of cross-functional alignment (and how to make it happen) • A proven process to keep teams united, focused, and customer-obsessed from day one Show notes and links: https://deeneyenterprises.com/qdd/podcast/s3e18/ Send us a message Support the show If your team is still catching problems too late — let's talk. → Schedule a free discovery call: Dianna's calendar Want insights like this? → Subscribe to my newsletter: qualityduringdesign.substack.com Get the full framework. → Pierce the Design Fog  ABOUT DIANNA Dianna Deeney is a quality advocate for product development with over 25 years of experience in manufacturing.

  2. Stop Being a Witness to Decisions That You Should be Helping to Shape

    Stop Being a Witness to Decisions That You Should be Helping to Shape

    Have you ever walked into a meeting (design review, planning session, phase gate) only to realize the decision was already made? That the discussion was just theater, not dialogue? You weren’t there to shape the outcome. You were there to witness it.  If that’s happened to you, you’re not alone. In this episode, Dianna explores why this happens, why it feels so frustrating, and most importantly how to fix it.  In this episode: • Design reviews are often theater because of the system: decisions are made before the meeting, not during • Real influence happens upstream, not in the formal meeting • Three practical steps to shape decisions before they’re locked in  Stop waiting for your moment to shine. Start shaping the moment before it happens. Share this with someone who’s been a witness too many times.

  4. Expected Value Makes Uncertainty Manageable

    Expected Value Makes Uncertainty Manageable

    Ever face a late-stage design decision where your gut says “maybe,” finance says “no,” and the schedule says “hurry”?  We unpack a simple way to make those calls with more clarity: using expected value to connect confidence, upside, and downside into one sober view of net benefit. No jargon, no spreadsheets required—just a clear framework that helps you see when a $50,000 test buys real certainty, and when the right move is to ship. Still, numbers don’t get the final say. The goal isn’t to pick the biggest EV; it’s to choose the most balanced, actionable, project-aligned option. If this approach helps you navigate the gray areas between risk and reward, follow the show, share it with a teammate, and leave a quick review so others can find it. Got a decision you’re wrestling with? Send it our way—we’ll feature it in a future breakdown.

  5. Define Kill Criteria to Avoid Zombie Projects

    Define Kill Criteria to Avoid Zombie Projects

    When pursuing aggressive benchmarks, engineers must employ portfolio thinking, running multiple design projects simultaneously. But choosing winners requires a decisive way to eliminate projects that are not feasible to continue innovating, often referred to as a "project killer".  In this episode, we analyze Tesla's battery development as a case study. We delve into their use of five clear-cut constraint categories that define failure conditions upfront: the Economic filter, Performance filter, Scalability filter, Resource filter, and System filter.  We discuss the challenges engineers face in letting go of projects due to the sunk cost fallacy, where prior investments irrationally influence future choices, leading to the creation of "zombie projects".  Learn why defining explicit kill criteria before development begins is a vital, often overlooked exercise that saves resources and ensures rational decision-making.
