How should a group of 100 people be divided into multiple Development Teams according to Scrum theory?

Dividing a group of 100 people into multiple Development Teams should be done with careful consideration of the skills required to deliver a product effectively. Using a predetermined skill set matrix ensures that each team is equipped with the necessary competencies to handle different aspects of development. This approach allows for balanced teams where individuals' strengths complement each other, leading to greater efficiency and productivity.

In Scrum, cross-functionality is key. Each Development Team should consist of members who collectively cover all the skills needed to deliver increments of the product. By organizing teams based on a skillset matrix, teams can be formed in such a way that they can work autonomously, meaning they have all the necessary skills within the team to accomplish their goals without relying heavily on external resources.

Other methods, such as random assignment or personal preferences, may lead to teams lacking essential skills or a good mix of expertise. Additionally, focusing solely on working hours could create teams that are not well-rounded in their abilities to address project requirements effectively. Thus, employing a skillset matrix aligns with Scrum principles, ensuring teams are equipped to deliver value in a collaborative and efficient manner.
