The teams using the SCRUM approach are typically high-performance teams with strong thinkers and doers. Typically, a team will be made up of 3 – 9 people with relevant skills who implement the majority of the processes needed (eg: analysing, designing, developing, testing and recording technical communication and documentation). The team used in SCRUM is self-organising but there will be scope for them to be overseen by someone with higher authority who is often referred to as the SCRUM master.
