Full description

People who are driven by the need to create real impact and who are willing to take unconventional measures to lead projects. Whether you are a PMO, project owner, project leader, team member or someone who invests time in temporary endeavours undertaken to create impact – this book is for you. The book is an inspiring and practical handbook designed to change our way of thinking and acting in and with projects.

It provides hands-on principles, methods and tools to help you realise projects with double the impact in half the time as well as real-life cases to show what it all looks like in practice. A handbook designed to enable us to go out and DO it ourselves.

In essence, the book extends the known agile methods with concrete methods for impact realisation, reflective leadership and a strong focus on how people are motivated and perform – it is all about placing an extreme focus on three core elements:

Impact: Unlike other agile methods, focus is on the effect of the project over the deliveries. Deliveries are a means of achieving the desired effect. To ensure quick effect, three methods are used: Impact case, impact solution design and pulse check.

Flow: The principle is to ensure a fast flow of ideas, results and learning. To create this flow, three methods are used which can be described very briefly as: Put the team together, create rhythm in the project and use visual methods.

Leadership: As a superstructure on other agile methods, Half Double focuses on leadership. This is ensured through the following managerial behavior: An active project owner, a collaborative project leader and a reflective and adaptive mindset: Both project owner and project manager should see changes in the environment as possibilities rather than threats. The focus must be on learning and adjustment, to ensure the greatest effect.

Readers statements

“While reading the Half Double book, I felt both deeply reassured and provoked. Reassured as the hands-on principles, methods and tools confirm what I believe to be the way forward. Provoked, as it also made me realize how caught up in the outdated way of thinking about and acting in projects we still are”

– Lars Sandahl Sørensen, Excutive Vice President, Chief Operating Officer, SAS, 2018 –

“I received the book Half Double a couple of days ago and read it almost all at once – terrific!!! Congrats on the initiative layout book and co-creation methodology – highly aligned with my own mindset! I have been working for many years publishing papers and advising companies about PM approach. The Half Double approach (impact; flow; leadership) has many of my thoughts supported and related to Project Design”.

Half Double is an easy to read, great colorful layout, energizing and inspirational book.

Who is airborn leadership?

As a project manager I have always lacked a platform where I could click in and get inspiration, relevant knowledge and concrete tools, regardless of time and place. A wireless toolbox where knowledge came to me through the air. A help that could give me a much needed boost in my current challenge.

You have never been more important as a project manager. Projects are the engine in developing a better business, new products, improvements in society and the global transformation to sustainable energy and production. Your leadership is therefore crucial. As a leader and project manager, you are the tool that creates the results.

I hope airborn leadership can be your gateway to knowledge within project management, no matter what journey you are on.
