Some insights from working with Flow-based product development

Software product development organizations operate in an environment of ever-increasing volatility, uncertainty, complexity, and ambiguity. The pace of change is accelerating, business and technology complexity is growing, and organizations are struggling to keep pace. The software development industry has a $300 billion productivity problem, according to one study. Value is not flowing as it should. Flow-based software development is part of the continued evolution of contemporary software development approaches contributing to addressing this problem. It builds on agile and lean software development approaches and incorporates lessons from Deming’s management method, the Toyota Production System, Lean Product Development, Theory of Constraints, Operations Management, and other influences. Flow-based development is foundational to modern systems approaches, including DevOps, Continuous Delivery, Site Reliability Engineering, and more. Creating and sustaining flow in organizations is a challenging problem. Drawing on insights developed over many years working with multiple global product development organizations, this session presents a framework for establishing, understanding, and sustaining flow in organizations.

I presented this session at the XP2020 conference. The slides are available here.

This session addressed the following questions:

  • What is flow?
  • What is the relationship between flow, lean, and agile?
  • Why do organizations adopt flow?
  • Where to get started?
  • What contributes to flow happening?
  • How do we measure flow?
  • What makes flow difficult to achieve?
  • How can organizations overcome these impediments to flow?
  • What is the role of culture in determining how effective flow can be?

Improving Flow in Large Software Product Development Organizations: A sensemaking and complex adaptive systems perspective

For my PhD research I studied several large software product development organizations to get a better understanding flow and impediments. Flow-based development is a rich and growing field with many concepts; the specific focus for this study is impediments to flow. This study takes the perspective that organizations are complex adaptive systems. This research uses sensemaking to get a richer, more-informed understanding of flow, impediments, and the context and culture of the organizations that are experiencing impediments to flow. The organizations that are part of this study are all large software product development organizations. The focus of this study, then, narrows to managing impediments to flow in large software product development organizations, using a sensemaking and complexity perspective.

Social Contracts, Simple Rules, and Self-Organization

This is the abstract and conclusions from a short paper I wrote and presented at the 15th International Conference on Agile Software Development (XP 2014) in Rome, Italy. A preprint version of the full paper is available here.


Teams and organizations are complex adaptive systems. Self- organization in complex adaptive systems evolves through a set of Simple Rules. Self-organization is a core tenet of agile teams. Self-organization does not mean everyone gets to do whatever they want to do. Team members create contracts with each other. These contracts create boundaries, or containers, within which self-organization can occur. Teams also create contracts with other teams, the wider organization and other stakeholders. The contracts are both implicit and explicit. Social contracts in complex adaptive systems are more effective if they are based on Simple Rules. Social Contract Theory acts as a lens through which we can better understand these social contracts in agile teams. This paper represents ongoing research that examines the role of Simple Rules and Social Contract Theory in fostering self-organization in agile development teams. The paper discusses four examples of social contracts in agile teams: definition of done, definition of ready, working agreements, and retrospectives.


This paper described the connection between Social Contract Theory and agile teams, viewing agile teams as complex adaptive systems. The field of Human Systems Dynamics provides a suitable lens through which to view teams and organizations as complex adaptive social systems, and defines necessary conditions for self- organization using Containers, Differences and Exchanges. The social contracts in agile teams and organizations are based on the Simple Rules that govern emergence and self-organization.

Simple Rules support coherent behaviors in a system. Definition of done, definition of ready, and working agreements are all examples of social contracts, created using Simple Rules, in agile teams and organizations. In addition, there are examples of social contracts to be found in retrospectives, including the prime directive, second directive and ground rules. These Simple Rules and Social Contracts support emergent behaviors and self-organization.

Teams own their own Simple Rules. As teams adapt their Simple Rules, new patterns are formed in the system. These patterns are governed by the social contracts created by the Simple Rules. Violating the Simple Rules creates a tension in the system that can be resolved by the team enforcing the rules or altering the rules (an Exchange intervention), or by the team membership changing (a Container intervention).
Social Contracts exist within agile teams, between agile teams, between agile teams and management, and within management teams.
