Gilb International

Kai Gilb, Tom Gilb, and team

The Gilb's are not ‘academic’ – but light, yet focused, and intensely practical. 

Tom Gilb and Kai Gilb have, together with many professional friends and clients, personally developed the methods they teach. The methods have been developed over decades of practice all over the world in both small companies and projects, as well as in the largest companies and projects.

Tom is the author of thirteen books and hundreds of papers on these and related subjects. His book ‘Competitive Engineering’ is a substantial definition of requirements ideas. His ideas on requirements are the acknowledged basis for CMMI level 4 (quantification, as initially developed at IBM from 1980). Tom has guest lectured at universities all over UK, Europe, China, India, USA, Korea – and has been a keynote speaker at dozens of technical conferences internationally.

Kai Gilb has partnered with Tom in developing these ideas, holding courses and practicing them with clients since 1992. He coach managers and product owners, write papers, develops the courses, has written the book, ‘Evo – Evolutionary Project Management & Product Development.’

Tom & Kai work well as a team; they approach the art of teaching the methods somewhat differently. Consequently, the students benefit from two different styles.

There are very many organizations and individuals who use some or all of their methods. IBM and HP were two early corporate adopters. Over the recent years, 20,000 engineers at Intel have adopted the Planguage requirements methods. Ericsson, Nokia, and A Major Multinational Finance Group use parts of their methods extensively. Many smaller companies also use the methods.

Biographical Summary 

Experience from decades of practice from all over the world in both tiny companies with tiny projects, as well as in some of the worlds largest companies and projects, is carefully incorporated through a relentless vision of excellence, farsightedness, clarity, efficiency, practicality, and simplicity.

Kai Gilb, coach -managers, -product owners and -development teams. He lectures, develops and runs workshops. He has written the book - ‘Evo – Evolutionary Project Management & Product Development.’ He writes papers, develops and hold training workshops and is consulting worldwide. He has developed the popular Value Requirements Online course. He assists project managers and teams during the projects startup, middle, delivery, and maintenance phases and is called in to save projects that have gone astray.

Kai has a drive to simplify (getting rid of nice but not critical information) and to purify the methods (distinguishing one idea from another). He is a keen observer of 'life' (the methods should reflect what is, not make its own reality) and logical. With this drive and mindset, he is continuously improving the methods.

Kai Gilb was teaching Agile project management long before the term existed (example: in 1993 teaching large corporations, like Ericsson and Nokia, working on complex projects (like mobile phone base stations and networks) to divide their projects into weekly cycles of value delivery. Today dividing the projects up into cycles is the norm, but the norm is to do it in regards to the solutions, and not the value, but Kai's mission is to change that. Today, Kai Gilb is at the forefront of changing peoples minds, motivating and teaching people on how to focus on delivering value (quality, improved, enhanced, better systems) as viewed by stakeholders.

His teaching recognizes the challenge of seeing things from a new perspective, and he loves to help people make the necessary paradigm shift.

He is a frequent keynote speaker, invited speaker, and tutorial speaker at international conferences.

His pro-bono activities are focused on all aspects of the Art of Living Foundation where he organizes courses and talks, he teaches, and he enjoys himself.

Kai is also involved with other Environmental (EPA) and Third-World Aid charities or organizations.

Kai Gilb is CEO of Gilb International and is currently working on numerous projects to serve the product development world even better.
