The book includes both technical engineering and team skills recognising that although technical expertise in a product design engineering team is indispensable it is only part of what is needed to make the team successful, with fellow engineers needing to work together effectively since product design is a team sport. The book also considers the need for an engineering team leader to manage change and take full advantage of the talents of individual team members. The team skills covered in the book are referred to as People Skills. ​
