Samenvatting
The gap between digital companies and companies that still need to make this change has widened in recent years. Bridging this gap is hard and needs persistence. Anneke Keller, previously CTO at Wehkamp and Head of Software Engineering at Coolblue and Jumbo, has led several digital transformations. She helped scale tech teams and technology to be able to accommodate growth (TomTom, Coolblue and Jumbo), single brand to multi-brand (Wehkamp), and modernise the technical architecture (all of the above). These experiences taught Anneke that technology teams, entire companies even, need a certain rhythm to adapt to change. A certain method that you can follow as a leader to support your team in growing to innovation. Anneke and Tims book "The Cherry Model" is about this method and gives plenty of examples from their experiences. Both successful and less successful, all with the intention for others to learn from it. The book is expected to be ready in August 2023
“IT is often evaluated based on hard skills. The resilience of architecture, the amount of coding languages you master, how many years of experience the tech department has. These aspects form the pit of the cherry. They are important, but none of them bring innovation. Soft skills do. Innovation grows when people learn from each other, work together and challenge each other. Soft skills are the cherry’s nutritious, sweet flesh that brings all the birds to the yard.” Anneke Keller created the Cherry Model based on 25 years of experience as innovation leader. Every tech organisation – entire companies even – have a rhythm for growth and change. After a summery phase of seemingly endless innovation inevitably follows a harsh season of stagnation and cutbacks. How can you as a leader predict and recognise these different phases and use them to support and create an innovative organisation? In The Cherry Model Anneke and her former colleague and technology guru Tim Meeuwissen guide you through the seasons of innovation sharing their stories, lively anecdotes and helpful tips and tricks. Anneke Keller worked as CTO and IT leader at Wehkamp, Jumbo, Coolblue, TomTom and KPN. Anneke owns a food forest where she grows fruit and vegetables for and with her neighbours. Tim Meeuwissen has a career in transforming organisations to create software that scales and lasts, and currently works at Jumbo. Tim is a tinkerer and a hobby farmer who keeps chickens, bees and a small flock of sheep.
