Dirk Lerner was engaged to coach my efforts of creating a data warehouse using data vault 2.0 architecture. It has been a pleasure to work with Dirk. The guidance given has greatly increased the quality of the design and sped up the entire process.
After the first six-month engagement, I put together a financial analysis to examine the ROI of this engagement. What was found is to reach the same point in the project without the coaching engagement would have cost us three times the cost of the coaching and would have expanded the timeline.
Therefore, engaging Dirk for coaching conceptual, logical and data vault data modeling was certainly worth it and would do it again without hesitation.
