The RAPPID Value Cycle

DOWNLOAD THE FULL DIAGRAM

The RAPPID Value Cycle is a structured, repeatable approach to generating measurable business value from data analytics. It progresses through four key milestones, creating a cycle of confident investments and real results.

  1. Prepare to invest → Milestone 1: Approved funding
    Companies assess readiness, identify value-generating initiatives, and secure investment with a clear business case aligned to strategic goals.

  2. Deliver insights → Milestone 2: Valuable insights
    Frameworks guide the development of accurate, valuable insights, ensuring that data analytics delivers insights that can drive value.

  3. Apply insights → Milestone 3: Embedded insights
    Insights are integrated into business processes, applications, and decision-making workflows to drive operational improvements and strategic outcomes.

  4. Recognise value → Milestone 4: Measurable value
    Companies measure and publish the impact of data-driven initiatives, ensuring continued investment in high-impact opportunities.

When value is recognised, the confidence to invest grows – refining strategies, driving innovation, and unlocking bigger and better opportunities.

"There are many books focused on the amazing potential of data and analytics. However, they often leave the reader excited but without a usable path on how to get there. Apart from being a fun and easy read, this book introduces an easy-to-follow framework to design a sustainable data and analytics roadmap to deliver continuous value. Going further, Zjaén and Karl provide practitioners with online collaborative tools and ability to share challenges and experience with a community of interest to progress faster. If you want to take data and analytics beyond the hype, this book will help you get there."

"This essential book guides leaders on becoming data-value-driven. During my research with 100+ Data, Analytics and AI Leaders in 2023 and 2024, I found their main challenges to be cultural, not technological. Business buy-in and adoption are crucial. Data, analytics and AI leaders are doing their best to speak the language of business. But business leaders must better understand how to generate value from data. Packed with practical advice, recipes, and frameworks, this book helps business, IT, and data, analytics and AI leaders converge at the intersection of data’s economic value. I am excited to use and share it."

"By prioritising a value-driven approach over a purely data-centric one, this book skilfully translates complex technical concepts into relatable narratives, making the journey from data to business value accessible to a wide audience. Instead of overwhelming the reader with technical details, Sjaén and Karl combine conventional approaches with modern data-driven strategies using practical, ready-to-implement frameworks. I can see immediate applications for this valuable content in my data-related postgraduate courses, exploring advanced analytics and its business implications. This book is an essential guide for leaders, professionals, and educators looking to confidently navigate – and teach – the evolving landscape of data analytics."
