    Why Simple Data Integrations Take Months & How to Fix Them (feat. Ilya Vladimirskiy)

    Episode Summary I’m incredibly excited to have Ilya back for the Season 1 finale. He was my very first guest in the pilot episode, and honestly, he helped me figure out this format - what works, what doesn’t, how to make the collaborative problem-solving feel authentic. So it felt only right to close this season by bringing him back full circle. In this finale, we tackle a frustratingly common scenario: a marketing stakeholder needs data from a new platform for critical quarterly forecasting, but the data team estimates four months to build the connector. Meanwhile, two hours disappear every morning into manual CSV downloads, cleanups, and copy-paste operations, a process that’s already caused a 50% error in pipeline analysis. What seems like a technical integration problem quickly reveals itself as something much deeper: an organizational breakdown in ownership, communication, and mutual understanding between business stakeholders and data teams. And true to form, Ilya immediately zeroes in on the people side of things. Problem Category: Data Integration & ETLRuntime: 40 minutes The Problem Submitted by: Anonymous Marketing ProfessionalIndustry Context: Company with established data infrastructure and quarterly business planning cycles Problem Framework Issue: Need data from the new marketing automation platform for quarterly forecasting, but building a connector will take four months, according to the data team. Currently manually downloading CSV files daily. Trigger: Quarterly planning cycle starts in 8 weeks. Currently spending 120 minutes every morning downloading, cleaning, and manually importing marketing data files. Last week, a copy-paste error threw off pipeline analysis by 50% - only caught because the numbers seemed unrealistic. Tension: The data team focuses on building robust, enterprise-grade connectors that take months to develop properly. While understanding their approach, there’s an immediate business need that can’t wait for the perfect solution. The manual process is unsustainable and risky, but the data is critical for business planning. Boundaries: * Cannot change the quarterly planning timeline (set by business cycle) * The marketing platform was selected by leadership and cannot be changed * The data team has limited capacity and other priorities * A budget exists for reasonable interim solutions * Must maintain data quality standards for forecasting accuracy Tech Stack: New marketing automation platform with CSV export capability, central data warehouse for forecasting (specific tools not disclosed) Clarity Statement: Need an interim solution to get marketing platform data into the data warehouse reliably within the next 8 weeks, without waiting for the full enterprise connector that will take 4 months. Our Guest IlyaFractional Head of Data & Data Leadership Consultant Ilya brings over 15 years of data experience, having led data functions at companies like Ada Health (symptom checker app), and various startups and scale-ups across Berlin and Munich. Originally from Moscow with a background in computational mathematics, he moved to Germany in 2002 and transitioned from database research to hands-on data engineering and leadership roles. After the biotech winter impacted Ada Health, Ilya pivoted to fractional and interim data leadership, helping companies build data platforms and teams across different domains and stages. Special Note: Ilya was our very first guest in the pilot episode and returns to close out Season 1, bringing his people-first philosophy full circle. Connect with Ilya: * LinkedIn: https://www.linkedin.com/in/bkmy43/ * YouTube: https://www.youtube.com/@lab4.berlin (Data leadership discussions while smoking pipes - yes, really, and it’s worth checking out) * Website: https://www.lab4.berlin/ The Breakthrough Discussion Initial Reactions Ilya and I immediately recognized this as a people problem disguised as a technical problem. As Ilya put it: “From most failing projects and situations like this, I rarely saw the root cause was technology or tools.” The four-month estimate raised red flags for both of us. As Ilya observed, connecting to an API of an existing marketing tool shouldn’t take four months - what’s likely happening is that “building a connector” actually means the entire pipeline: getting the data, integrating it into the company data model, and delivering it through BI tools with proper business logic. The Real Problem Through the reflection break and collaborative discussion, we identified the core issues: * Communication Breakdown: The data team likely down-prioritized this request because other initiatives have a higher business impact, but they haven’t articulated this clearly. The stakeholder hears “four months” without understanding what’s blocking it. * Ownership Confusion: It’s unclear who owns the decision about prioritization and tradeoffs. Without clear ownership, every request becomes a negotiation rather than a strategic decision. * Missing Context: The data team probably doesn’t understand the business impact of the delay (corrupted forecasts, wasted ad spend, strategic planning delays). The stakeholder doesn’t understand what the data team is actually building and why it takes time. * Us vs Them Dynamic: The situation has devolved into adversarial positioning - “the data team won’t help me” versus “stakeholders want everything immediately” - rather than collaborative problem-solving. The Solution Approach Rather than a single technical fix, our discussion produced a multi-layered solution: Immediate Relief (Week 1-2): Ask one of the engineers to build a simple Python script or similar automation. This doesn’t need to be production-grade infrastructure - just something that reliably pulls the CSV, does basic transformation, and loads it into the warehouse. This can be a 2-3 day task rather than a 4-month project. Transparency & Context (Week 2-3): Create a visible initiative backlog overview showing everything the data team is working on. When someone says “it will take four months,” they should be able to show exactly what’s blocking it and why those other priorities matter more. This isn’t about justifying delays - it’s about enabling informed decisions. Rational Decision Framework (Week 3-4): Develop a structured way to articulate both the cost of building solutions and the business impact of delays. Put numbers on the table: What does two hours of manual work daily cost? What’s the risk value of potential forecast errors? What’s the opportunity cost of the data team working on this versus their current priorities? Strategic Alignment (Ongoing): Establish clear ownership and a prioritization process that considers both technical complexity and business impact. This isn’t about the data team gatekeeping or stakeholders demanding - it’s about having a framework where tradeoffs are visible and decisions are rational. Key Takeaways 3 Critical Insights * This is an Organizational Problem, Not a Technical One: The four-month timeline isn’t about technical complexity - it’s about priorities, communication, and organizational dynamics. The actual technical work of connecting to an API could be done much faster if approached as a quick automation rather than an enterprise-grade infrastructure. * The “Us vs Them” Dynamic Is Killing Efficiency: When stakeholders and data teams position themselves as adversaries rather than collaborators, every interaction becomes a negotiation. The marketing person sees the data team as obstructionist; the data team sees stakeholders as demanding and unrealistic. Neither side wins in this dynamic, and the business suffers. * Ownership Clarity Is Essential: Without clear ownership of prioritization decisions, every data request becomes contested territory. Someone needs to own the decision about whether a four-month wait is acceptable given the business impact, and that person needs visibility into both the technical constraints and business consequences. 4 Action Items For the Problem Submitter (and anyone in similar situations): * Request a Quick Automation Script (This Week) - Ask a data engineer to build a simple Python script or similar automation that pulls the CSV, does basic transformation, and loads it into your warehouse. Make it clear this doesn’t need to be production-grade infrastructure - just something reliable enough to bridge the gap. Timeline: 2-3 days of engineering time. * Create Initiative Backlog Visibility (Week 2) - Work with the data team to create a visible overview of all current initiatives. When told something will take four months, you should understand what’s blocking it and why those priorities were chosen. This isn’t about challenging their decisions - it’s about having context for informed discussion. * Articulate Cost and Impact With Numbers (Week 3) - Document the actual business impact: two hours daily of manual work (cost it out by salary), risk of forecast errors (quantify the potential impact), strategic planning delays (what decisions are being made without this data?). Similarly, ask the data team to articulate what they’d need to deprioritize to tackle this sooner. * Establish Ongoing Prioritization Framework (Week 4+) - Work with leadership to create a clear process for prioritizing data work that considers both technical complexity and business impact. Identify who owns these decisions and ensure they have visibility into both technical constraints and business consequences. This prevents future “four months” surprises. Episode Highlights * 02:00 - Problem reveal: Four months for a marketing platform connector * 06:30 - Ilya’s immediate diagnosis: “This is a people problem, not a technical one” * 14:45 - Post-reflection discussion: Unpacking the communication breakdown * 24:30 - The ownership question: Who actually decides priorities? * 31:00 - Quick wins vs long-term solutions

Tiankai Feng (Director of Data & AI Strategy at ThoughtWorks, author of "Humanizing Data Strategy" and "Humanizing AI Strategy") and host Lior Barak tackle a manufacturing company where plant managers with 20+ years of experience resist a modern data platform. Problem Category: Organizational Data Strategy / Change ManagementRuntime: 32 minutes The Challenge: A family-owned manufacturer invested heavily in data infrastructure, but plant managers still make decisions based on "what happened last time" and gut instincts, creating a divide between analytics teams and operations. The Solution: Transform data from replacement threat to support tool through co-creation, clear communication about expertise-data synergy, and defining decision-making rules with proper incentives. Key Takeaways: Expertise vs. data is always a tension field - communicate how they work hand-in-hand, not against each other People don't use things they didn't help create - co-creation is essential for adoption Success metrics must reflect both short-term and long-term value to align incentives properly Guest: Tiankai Feng, Director of Data & AI Strategy at ThoughtWorks Author of "Humanizing Data Strategy" and "Humanizing AI Strategy" Connect: https://www.linkedin.com/in/tiankaifeng/ Get Involved: Submit your data problem or Become a guest: https://data-breakthroughs-podcast.cookingdata.blog/ Join the conversation: #DataBreakthrough Full show notes: https://data-breakthroughs-podcast.cookingdata.blog/ Disclaimer: This podcast is for inspiration and educational purposes.

    How to Manage Analytics Overload & Build Effective Dashboards (feat. Eva Schreyer)

    Data Breakthroughs - Episode 09: When Analytics Becomes a Dashboard Factory Real-world data problem solving in action! Eva Schreyer (Head of Data & Analytics at Neugelb/Commerzbank) and host Lior Barak tackle a community-submitted challenge about analytics overload for the first time during recording. Problem Category: Business Intelligence & Dashboarding / Organizational Data StrategyRuntime: 37 minutes The Challenge: A product team drowns in 40+ charts per report while struggling to make data-driven decisions, creating a disconnect between analytics investment and business value. The Solution: Transform from dashboard factory to strategic partner through executive alignment, monetizing requests, and prioritizing deep-dive analyses over generic reporting. Key Takeaways: Too much data doesn't mean good decisions-relevance matters more than volume Making stakeholders understand the cost of requests (in time/effort) dramatically improves prioritization Ask "what will you do differently when this metric changes?" to identify truly actionable insights Guest: Eva Schreyer, Head of Data & Analytics at Neugelb (Commerzbank) Connect: https://www.linkedin.com/in/eva-schreyer/ Get Involved: Submit your data problem: https://data-breakthroughs-podcast.cookingdata.blog/ Become a guest: https://data-breakthroughs-podcast.cookingdata.blog/ Join the conversation: #DataBreakthrough Full show notes & visual diagrams: https://data-breakthroughs-podcast.cookingdata.blog/ Disclaimer: This podcast is for inspiration and educational purposes.

    Why Your Perfect Model Fails in Production: The Accuracy Paradox (feat. Irena Bojarovska)

    Data Breakthroughs - Episode 8: The Office Kitchen Paradox Real-world data problem solving in action! Irena Bojarovska and host Lior Barak tackle a community-submitted challenge for the first time during the recording. Problem Category: Machine Learning & AI Implementation Runtime: 50 minutes The Challenge: A hackathon team built a smart kitchen demand forecasting model with 91% accuracy, but the company is still throwing away 20-25% of fresh products weekly while running out of popular items. The Solution: The breakthrough isn't about fixing the model, it's about fixing the data. The model is missing critical inputs (office attendance, special events) and is operating blindly due to data quality problems. The real solution combines better data, human-AI collaboration, and proper A/B testing. Key Takeaways: • Model accuracy ≠ real-world performance (91% test accuracy doesn't guarantee waste reduction) • Data quality and contextual information are your foundation (garbage in, garbage out) • Humans should augment the model, not be replaced by it (hybrid approach wins) Guest: Irena Bojarovska, Data Scientist at Zalando SEConnect: https://www.linkedin.com/in/irenabojarovska/ Get Involved: Submit your data problem: https://data-breakthroughs-podcast.cookingdata.blog/submit-problem Become a guest: https://data-breakthroughs-podcast.cookingdata.blog/become-guest Join the conversation: #DataBreakthrough Full show notes & visual diagrams: https://wabi-sabi-data-newsletter.com [or your actual newsletter link] Figma Board: https://www.figma.com/board/jfC4ipNvd8zSPIyZreEten/Irena-Bojarovska?node-id=1-14&t=Q46O2Ae9yuRHZRwy-1 Disclaimer: This podcast is for inspiration and educational purposes.

    How to Compete Against AI-Powered Competitors With Limited Resources (feat. Jon Cooke)

    Data Breakthroughs - Episode 7: Small Company vs AI Giants Real-world data problem solving in action! Jon Cooke (Founder of Dataception) and host Lior Barak tackle a classic David vs. Goliath scenario for the first time during the recording. Problem Category: Data Strategy & Customer AnalyticsRuntime: 36 minutes The Challenge: Small German seed company (7 people) with 600+ product varieties, 4 years of customer data, and 30 years of gardening expertise. They're losing to giants who use algorithms for personalized recommendations. Conversion rate: 2.1%. Sent tomato seeds in December while competitors suggested microgreens and winter planning guides. They have incredible data and domain knowledge - but no idea how to compete with automated personalization. The Solution: You don't need massive tech teams. Start with customer segmentation workshops, map buying journeys, understand your data quality, build a simple recommendation engine (could be done in half a day), and test with friendly customers. The institutional knowledge trapped in people's heads is your competitive advantage - you just need to capture and automate it. Key Takeaways: Understand customers and segments first - technology second Data quality dictates approach: good data = ML models, poor data = heuristic rules Simple models beat no models - you don't need world-class data scientists This is a business process problem with AI tools, not an AI problem Small teams can compete by moving fast and testing with customers Guest: Jon Cooke, Founder of Dataception20 years in data & AI | Former Databricks Solutions Architecture Lead | Ex-PwCExpert in data products, GenAI, and knowledge graphs Connect with Jon: Website: https://dataception.com LinkedIn Company: Dataception Get Involved: Submit your data problem: https://data-breakthroughs-podcast.cookingdata.blog/submit-problemBecome a guest: https://data-breakthroughs-podcast.cookingdata.blog/become-guestJoin the conversation: #DataBreakthrough Full show notes & visual diagrams: [Link to newsletter version] Disclaimer: This podcast is for inspiration and educational purposes.

    How to Build Explainable AI Models & Prevent Regulatory Disasters (feat. Elizabeth Press)

    Data Breakthroughs - Episode 6: AI Bias & Explainability Crisis Real-world data problem solving in action! Elizabeth Press (Founder of D3M Labs, Deputy Chief Digital Officer at CHESCO) and host Lior Barak tackle one of AI’s most critical challenges for the first time during the recording. Problem Category: Machine Learning & AI Implementation / AI EthicsRuntime: 36 minutes The Challenge: A deep learning loan approval model improved accuracy by 23% and reduced processing time from days to minutes. Business results? Phenomenal. The problem? It systematically denies qualified applicants in certain zip codes at 40% higher rates - and the model is a black box that can’t explain individual decisions. Regulatory examination in 12 weeks. Potential discrimination lawsuits are looming. The Solution: Not all use cases should use unexplainable AI. Return to statistical fundamentals (logistic regression), implement hybrid human-in-loop systems, create cross-functional teams involving legal from day one, build test boxes for domain validation, and establish decision logs. Sometimes boring statistics beat sexy deep learning. Key Takeaways: High-stakes decisions (loans, justice, healthcare) should never use unexplainable black box models Involve legal, PR, and domain experts from the start - not retroactively Bias is quantifiable through business metrics (churn, customer complaints, defaults) You must be able to explain your model - without it, you run into catastrophic risks Speed means nothing if accuracy and ethics are compromised Guest: Elizabeth Press, Founder of D3M Labs | Deputy Chief Digital Officer at CHESCO.

    How to Align Customer Definitions Across Departments & Prevent VIP Tier Conflicts (feat. David Cohen)

    Episode Summary Every department in your company defines “most valuable customer” differently. Sales prioritizes deal size, Support focuses on customer success scores, and Product values feature adoption rates. The result? The same customer gets treated as both VIP and basic-tier depending on which team they interact with—creating confusion, frustration, and missed revenue opportunities. In this episode, David Cohen and host Lior Barak tackle this organizational alignment nightmare head-on, discovering the root causes and building a practical framework for creating unified customer definitions across your entire company.This episode is different. We’re not debugging code or fixing data pipelines. We’re solving the messy human problem underneath the metrics. Problem Category: Organizational Data StrategyRuntime: 32 minutes The Problem Submitted by: AnonymousIndustry Context: Company with multiple departments (Sales, Support, Product, Marketing) Problem Framework * Issue: Every department in the company defines “most valuable customer” differently, making it impossible to create a coherent strategy or provide a consistent customer experience. * Trigger: Launched a new VIP customer experience program last quarter. It turned into chaos. The same customers could be treated as high-value by sales (big contract) while getting basic support (low engagement score) and irrelevant marketing (different segment). Customers started complaining about inconsistent treatment. * Tension: * Each department insists its customer view is correct for their function * Need one authoritative definition to guide the company's strategy * Every stakeholder meeting devolves into arguments about whose metrics matter most * Providing a confusing, fragmented experience to customers who don’t understand why treatment varies by team * Current State: * Sales ranks by revenue * Support ranks by engagement frequency * Product ranks by feature usage * Marketing has its own segmentation based on campaign responses * Boundaries: No master data management or unified customer scoring exists * Tech Stack: Salesforce, Zendesk, product analytics platform, email marketing tools * Clarity Statement: “Overcome the human problem of indecision in defining what value looks like and who in our customer base gets the most of it.” Our Guest David CohenFounder | Superposition David runs a consulting firm that builds strategy workshops to help other consultancies in the data and AI spaces be more effective. He specializes in discovery processes for complicated and ambiguous client-facing projects, as well as internal growth needs for consultancies. What makes David unique: He treats organizational alignment problems the way a workshop designer thinks - creating settings where ego can surface safely, conflicts can be resolved productively, and consensus can emerge from structured activities. Background: * Founder of Superposition consulting firm * Specializes in strategy workshops for data/AI consultancies * Expert in discovery processes for ambiguous projects * Deep experience with stakeholder alignment challenges * Long-time consultant and self-described “data nerd” Philosophy: “This is actually a people problem and an ego problem rather than a technology or data one. The primary challenge is that we have an organization that does not agree on what value means.” Connect with David: * Website: https://www.superpositionstrat.com/ * LinkedIn: https://www.linkedin.com/in/davcohen06/ The Solution The Core Insight: You Need Therapy, Not Dashboards Both David and Lior independently arrived at the same conclusion during their 15-minute brainstorm: This is an ego problem disguised as a metrics problem. The departments aren’t confused about data. They’re protecting territory, defending their worldview, and fighting for organizational influence. No amount of data warehousing will fix that. The Workshop-Based Alignment Process Phase 1: Bring Everyone Together (Physically) * Create a dedicated event or series of sessions * In-person preferred (virtual as backup) * Representatives from each pillar: Sales, Support, Product, Marketing, and any others * Designate a leadership advocate with decision-making power * Consider retaining external facilitator to provide unbiased perspective Phase 2: Structure for Open Sharing * Create a setting where people can openly share concerns * Allow teams to express why their definition is “right” * Let people complain freely in a controlled space * Focus on logic, not debate club tactics * Use “yes, and” building rather than defensive arguing Phase 3: Define Value (Not Metrics) * Don’t jump to building anything yet * Start at the highest level: What does it mean to provide value to a customer? * Create a shared glossary of terms * Define what a VIP customer persona looks like (like defining an ICP) * Acknowledge that value to the customer ≠ is profitable to the company (potential wrinkle) Phase 4: Discard Before You Add * Define which metrics DON’T matter (easier than agreeing on which do) * Narrow the working area by elimination * Run the same 3 customers through each department’s current definition * Make the problem visible: Show how different the results are Phase 5: Force the Conflict Productively * Use the process to short-circuit the disconnect * Each team selects a representative to defend their position * Stack-rank existing customers to surface disagreements * Designated leader has a tiebreaker vote (counts as double/triple) * A leader can supersede loud voices and give time to quieter teams Phase 6: Build the Unified Definition * Create one persona of what a VIP customer is * Allow teams to bring their data sources to the table * Build a composite formula that incorporates multiple perspectives * Review definitions with executives for sign-off * Document what “valuable customer” means company-wide Phase 7: Implementation * Build dashboards and reports based on agreed metrics * Create an implementation plan to roll out the new customer experience * Establish consistent treatment across all touchpoints * Measure the success of the unified approach Critical Success Factors 1. Leadership Buy-In is Non-Negotiable. Without a leader who can make final decisions, this process never ends. You need someone with: * Tiebreaker vote authority * Power to supersede loud voices * Ability to give time to teams that don’t naturally speak up * Executive backing to enforce the decision 2. Consider External Facilitation. Why consultants exist for this type of work: * Unbiased third party with no territorial stake * Can “be the bad guy,” so internal leaders don’t have to * Expertise in facilitating difficult conversations * No emotional attachment to any department’s metrics * Acts as an organizational therapist 3. Assume Resistance (Because It’s Real) One assumption David made: At least one department won’t want to participate. This is realistic. The process must account for: * Political dynamics * Ego protection * Fear of losing influence * Concern about “wrong” metrics winning Visual Diagram Key Takeaways 3 Critical Insights * This is an Ego Problem, Not a Data Problem: The departments aren’t confused about metrics - they’re protecting territory and defending worldviews. Sales doesn’t actually think engagement frequency is wrong; they just don’t want Support’s definition to override theirs. You’re not solving for understanding the valuable customer. You’re solving for misalignment within your team. Treat it accordingly. * Leadership Buy-In Determines Success or Failure: Without leadership mandate and a designated decision-maker, any efforts to solve this problem will inevitably fail. You need someone who can break ties, settle disputes, and enforce the final decision. Otherwise, you’ll cycle through endless stakeholder meetings that go nowhere. * Internal Definitions Can Differ - Customer-Facing Ones Cannot: It’s actually fine if Sales, Support, Product, and Marketing measure success differently internally for their own optimization. The problem is when those different definitions create inconsistent customer experiences. You need a united front when it touches customers, even if internal reporting varies. 4 Action Items For the next 90 days: * Week 1-2: Set Up the Alignment Event(s) - Bring everybody together, preferably in person. Schedule dedicated time (potentially a full week) for working sessions. Identify which teams need representation beyond Sales/Support/Product/Marketing (HR? Customer Success? Finance?). Designate a leadership advocate who will serve as decision-maker and facilitator. * Week 1-2: Decide on External Support - Evaluate whether to retain an outside consultant or facilitator to manage the process. Consider: Do you have someone internal who can be unbiased? Can your leader afford to “be the bad guy”? Is there enough trust for self-facilitation? External help speeds the process and protects internal relationships. * Week 3-4: Run the Same 3 Customers Through Different Definitions - Make the problem visceral and visible. Show numerically how differently each department would treat the same customers. This activity surfaces the chaos in a way that’s hard to argue with. Use it early in sessions to build urgency for alignment. * Week 4-12: Conduct the Alignment Sessions - Use structured workshop activities (see GameStorming book reference) to: * Define shared language and glossary * Build a unified customer value definition * Create VIP customer persona * Stack-rank existing customers using the new definition * Document metrics and data sources * Build an implementation roadmap Episode Highlights * 01:41 - “DO NOT TOUCH FINAL FINAL” - The universal file naming disaster * 03:04 - Bad data tastes like unflavored cornflakes * 07:02 - Clarity emerges: Defining what value means * 08:25 - Critical assumption: Leadership buy-in exists (or doe
