Disciplined Agile Delivery: A Practitioner’s Guide to Efficient Project Management

Unleashing Project Excellence with Disciplined Agile Delivery

Disciplined Agile Delivery (DAD) is an organizing process framework that provides engineering guidance on enterprise solution delivery. DAD combines various agile and lean practices and tailors them to fit the unique needs of each product owner. The framework emphasizes the importance of context, allowing teams to make informed decisions based on their specific situation.

At its core, DAD supports a full lifecycle approach to solution delivery, from initial planning to production deployment and maintenance. This disciplined agile toolkit approach ensures that all aspects of the engineering development process are considered, including architecture, design, testing, and deployment. Additionally, DAD is well-suited for enterprise environments and promotes the adoption of disciplined DevOps practices.

One of the key features of the Disciplined Agile Toolkit (DAD) is its focus on roles in agile software development. The framework includes a range of roles, including team members, stakeholders, product owners, and process champions, each with their own responsibilities and goals. This clear delineation of roles helps ensure that everyone involved in agile teams is working towards a common goal.

Another important aspect of DAD is its set of principles that align with agile software development and agile methods. These principles guide decision-making and promote collaboration among the product owner and engineering teams, leading to continuous improvement. They include things like “be enterprise aware,” “deliver consumable solutions,” “embrace changing requirements,” and “validate quality continuously.” By following these principles, teams can ensure that they are making informed decisions that will lead to successful outcomes.

So how does DAD work in practice?

Essentially, it provides a flexible yet structured approach to engineering solution delivery using agile methods. Teams within an enterprise can choose which process decisions they want to adopt based on their specific needs while still adhering to the overall framework guidelines.

The history of DAD dates back to 2009 when Scott Ambler first introduced it as an extension of his earlier work on Agile Modeling (AM). Since then, it has evolved into a comprehensive process framework used by organizations around the world. The framework emphasizes the importance of the product owner in driving the project’s success, while also emphasizing the engineering and team member roles in delivering high-quality results.

While Ambler is often credited as the inventor of DAD, he himself acknowledges that it was developed collaboratively with input from many other experts in the field, including the product owner. This collaborative approach reflects one of the key values promoted by DAD: teamwork.

Understanding the Concept of DAD: A Comprehensive Overview

Tailoring Agile Development with DAD


Disciplined Agile Delivery (DAD) is a hybrid agile approach that integrates various methodologies and frameworks to provide a comprehensive solution for software development. It emphasizes the importance of tailoring the process to fit the specific needs of the project, team, and organization.


The DAD framework consists of three phases: Inception, Construction, and Transition, each with its set of activities and milestones. The Inception phase involves defining the scope of the project, identifying stakeholders’ needs, creating a high-level plan, and establishing governance with team members. The Construction phase includes developing working software in iterations while addressing technical debt and quality concerns with team members. Finally, the Transition phase focuses on deploying the software into production while ensuring user adoption and feedback from team members.


DAD also provides guidance on how to address common challenges in agile development such as scaling, governance, and enterprise alignment. For example, it offers strategies for scaling agile practices across teams or departments using coordination techniques such as Scrum-of-Scrums or Communities-of-Practice. It also provides guidance on how to align agile delivery with organizational goals by incorporating lean principles or DevOps practices. Additionally, DAD offers techniques for managing work items effectively throughout the development process.


By adopting DAD, organizations can achieve a disciplined yet flexible approach to software development that balances agility with pragmatism. This approach helps teams deliver high-quality software that meets stakeholders’ needs while adapting to changing requirements throughout the project lifecycle. It promotes collaboration between business stakeholders and technical teams by providing a common language for communication.

One example of successful implementation of DAD is at IBM Rational’s Collaborative Lifecycle Management (CLM) product line. CLM used Disciplined Agile IT to integrate multiple products into an end-to-end solution for application lifecycle management (ALM). By doing so, they were able to improve their release cycle time from 12 months down to 3 months while reducing overhead costs by 50%. The team member played a crucial role in the success of the implementation.

DAD Framework and Methodology: Phases and Lifecycle Types

Agile methodologies have been gaining popularity in software development for its ability to deliver quality products quickly. However, as organizations grow and projects become more complex, a disciplined approach is required to handle the challenges effectively. This is where Disciplined Agile Delivery (DAD) comes into play. DAD provides a hybrid framework that combines agile and lean principles with traditional project management practices. In this section, we will discuss the three lifecycle types of DAD and their phases, which involve team members at every stage.

Agile/Basic Lifecycle

The Agile/Basic lifecycle type is ideal for small teams working on simple projects that do not require extensive planning. It consists of three phases: Inception, Construction, and Transition. There are no da additional keywords to be added.

Inception Phase: During this phase, the team identifies the scope of the project, defines the requirements, creates a high-level plan, and establishes communication channels among stakeholders.

Construction Phase: This phase involves building the product incrementally through iterations or sprints. The team focuses on delivering value by prioritizing features based on customer feedback.

Transition Phase: In this final phase, the team ensures that all deliverables are complete and meet acceptance criteria before deploying them to production. They also conduct training sessions for end-users and provide support during initial usage.

Lean/Advanced Lifecycle

The Lean/Advanced lifecycle type is suitable for large-scale projects that require extensive planning and coordination across multiple teams. It consists of seven phases: Inception, Construction Iteration, Release Iteration, Production, Retirement, and Operations.

Inception Phase: Similar to the Agile/Basic lifecycle type’s inception phase; however, it includes additional activities such as establishing governance structures and identifying risks.

Construction Iteration Phase: This phase involves building increments similar to agile methodology but with an emphasis on continuous integration and testing.

Release Iteration Phase: The team prepares for release by conducting user acceptance testing (UAT), and creating deployment plans while ensuring compliance with regulatory standards if any.

Production Phase: Once the product is deployed, the team provides support and maintenance to ensure smooth operations.

Retirement Phase: This phase involves retiring the product or its components that are no longer needed.

Operations Phase: In this final phase, the team monitors and optimizes the product’s performance based on feedback from end-users.

Continuous Improvement Lifecycle

The Continuous Improvement lifecycle type is designed for organizations that seek to improve their delivery capabilities continually. It consists of two phases: Improve and Govern.

Improve Phase: During this phase, the team identifies areas for improvement in their processes, tools, and techniques. They also experiment with new ideas and implement changes that deliver value.

Govern Phase: This phase focuses on ensuring compliance with organizational policies, and standards while providing governance structures for decision-making at all levels of the organization.

DAD’s Strengths and Weaknesses: A Practical Guide

Toolkit as a Major Strength

Disciplined Agile Delivery (DAD) is an agile delivery framework that offers a wide range of methods and tools to help people meet their responsibilities in various circumstances. One of the major strengths of DAD is its toolkit, which includes techniques for architecture, design, testing, governance, and many more. The toolkit provides guidance on how to apply agile practices effectively in different situations.

The DAD toolkit helps teams achieve better outcomes by providing them with clear guidance on how to approach different aspects of software development. For example, the architecture techniques help teams create a design that meets their needs while also ensuring that it is scalable and maintainable. Similarly, the testing techniques help teams ensure that the software they develop meets the required quality standards.

Adaptability as Another Benefit

Another benefit of DAD is its adaptability. It can be tailored to meet the needs of different users, making it a highly adaptable approach. This adaptability allows organizations to customize DAD according to their specific requirements and constraints.

For instance, some organizations may need to follow strict regulatory compliance requirements while others may have limited resources or budget constraints. In such cases, DAD can be customized accordingly by selecting appropriate methods from its toolkit.

Flexibility as a Challenge

However, this flexibility can also be a weakness if not utilized properly. It requires discipline and careful attention to detail to ensure that the right methods are used in the right circumstances. To get the most out of DAD’s benefits, people need to understand their responsibilities and use the toolkit effectively.

This can be challenging for those who are new to agile delivery or who lack experience in using DAD’s toolkit effectively. Moreover, there is always a risk of over-customizing or under-utilizing DAD’s methods if not implemented correctly.

Potential Supporting Roles in DAD: Model Team Roles

Model Team Roles in Disciplined Agile Delivery

Disciplined Agile Delivery (DAD) is a framework that provides guidance on how to effectively deliver solutions in an agile manner. One of the key features of DAD is its flexibility, allowing teams to tailor their approach based on the specific needs of the project. In addition to the core team roles, DAD defines several potential supporting roles that can be added to a team. These roles are not mandatory, but they can help improve the overall performance of the team and ensure that all necessary tasks are completed.

Architecture Owner: Ensuring Technical Alignment

The Architecture Owner is responsible for ensuring that the technical decisions made by the team align with the overall architectural vision for the project. This role helps ensure that technical debt is avoided and that decisions are made with a long-term perspective in mind. The Architecture Owner works closely with other team members to identify technical risks and opportunities and make informed decisions about how best to proceed.

Independent Tester: Testing from an End-User Perspective

The Independent Tester is responsible for testing the system from an end-user perspective and providing feedback to the team. This role helps ensure that all aspects of user experience are considered during development, including usability, accessibility, and performance. The Independent Tester works closely with developers to identify defects early in the development process and provide feedback on potential improvements.

Technical Writer: Creating Documentation

The Technical Writer is responsible for creating documentation that helps team members understand how to use and maintain the system. This role ensures that knowledge about how different parts of the system work together is captured and shared among team members. The Technical Writer works closely with other team members to understand their needs for documentation and create content that meets those needs.

Data Administrator: Managing Data Used by System

The Data Administrator is responsible for managing data used by the system and ensuring that it is accurate and up-to-date. This role helps ensure that data integrity is maintained throughout development and that data is properly secured. The Data Administrator works closely with other team members to understand their data needs and ensure that the system is designed to support those needs.

Adopting a Hybrid Strategy for Successful Application of DAD

Adopting a hybrid approach can be a successful strategy for implementing Disciplined Agile Delivery (DAD). DAD is an agile methodology that provides guidance and practices to help teams tailor their solution delivery process. A hybrid approach combines the best of both agile and traditional project management methodologies. This approach allows teams to tailor their solution to the specific needs of their project.

One way to adopt a hybrid approach is by using agile sprints within a traditional waterfall framework. This means that the project will follow a linear sequence of phases, but each phase will include multiple sprints. By doing so, you can achieve the benefits of both approaches: you have clear milestones and deliverables as in waterfall, and you also have flexibility and continuous feedback as in agile.

Another way to adopt a hybrid approach is by using different methodologies for different parts of the project. For example, use Scrum for development activities while following Prince2 or PMBOK guidelines for governance and control activities. This allows you to balance agility with control.

The result of a successful hybrid strategy is a more flexible and adaptable project delivery process. You are not tied down to one methodology; instead, you have the freedom to choose what works best for your team’s specific needs. By doing so, you can reduce risks, increase efficiency, improve quality, and enhance customer satisfaction.

DAD vs. SAFE: A Guide to the Scaled Agile Framework

Flexibility and efficiency are crucial in software development, especially since there are significant differences between them that organizations should consider before choosing which one to adopt.

Customizability of DAD

One of the key advantages of DAD is its flexibility and customizability. Unlike SAFE, which has a set of defined roles, ceremonies, and artifacts, DAD allows teams to tailor their approach based on their specific needs. This means that teams can choose from a range of process options and tailor them according to their unique circumstances.

For example, a team may opt for an agile/lean hybrid approach if they need more structure than pure agile but don’t want the overhead associated with traditional project management methodologies. Alternatively, they may choose a continuous delivery approach if they need to release code frequently without sacrificing quality.

The customizability of DAD makes it ideal for organizations with complex or unique requirements. However, this flexibility also means that teams must be disciplined in selecting the right processes for their needs. If not implemented correctly, it could lead to confusion or inefficiencies within the team.

Prescriptiveness of SAFE

In contrast, SAFE provides a more prescriptive approach with predefined roles and ceremonies designed to ensure consistency across large-scale projects. This framework is ideal for organizations that require standardized processes across multiple teams or departments.

SAFE’s predefined roles include Product Owner, Scrum Master, Release Train Engineer (RTE), and Business Owner. These roles provide clear responsibilities and accountability within the organization while ensuring alignment with business objectives.

SAFE includes several ceremonies such as Program Increment (PI) Planning and System Demo designed to facilitate communication between teams while providing visibility into project progress.

Choosing the Right Framework

Ultimately, choosing the right framework depends on an organization’s size, culture, and goals. While DAD provides greater flexibility, it requires more discipline in selecting the right processes for each team. On the other hand, SAFE provides a more prescriptive approach that ensures consistency across large-scale projects but may not be suitable for smaller organizations or those with unique requirements.

It’s also worth noting that both frameworks require effective implementation and continuous improvement to achieve optimal results. Organizations should regularly review their chosen framework and make adjustments as necessary to ensure they are meeting their objectives.

Which One to Choose? DAD vs. SAFE Comparison

DAD vs. SAFE: Which One to Choose?

Agile delivery frameworks have gained immense popularity in recent years due to their ability to adapt and respond quickly to changing business needs. Two of the most well-known agile delivery frameworks are Disciplined Agile Delivery (DAD) and Scaled Agile Framework (SAFE). While both aim to improve organizational agility, they differ in their approach and focus. In this section, we will compare DAD and SAFE and help you choose which one is best suited for your organization.

Flexible vs Prescriptive

One of the key differences between DAD and SAFE is their level of flexibility. DAD is a flexible framework that allows organizations to tailor their approach based on their specific needs and context. It provides a comprehensive toolkit that includes various practices, strategies, and techniques for teams to choose from based on what works best for them. This flexibility makes it easier for organizations to adopt agile practices without having to change everything overnight.

On the other hand, SAFE is more prescriptive than DAD as it provides a detailed set of guidelines for scaling agile practices across large organizations. It offers specific roles, ceremonies, artifacts, and metrics that teams must follow in order to achieve success at scale. While this can be helpful for larger organizations with complex structures and multiple teams working on different projects simultaneously, it may not be suitable for smaller organizations or those with less complex structures.

Scaling Agility

Another significant difference between DAD and SAFE is their approach toward scaling agility. SAFE was specifically designed as a framework for large-scale enterprises that need to coordinate multiple teams working on different projects simultaneously. It provides guidance on how teams can work together more effectively by aligning objectives, improving communication channels, increasing transparency, and reducing dependencies.

In contrast, while DAD does provide some guidance around scaling agility within an organization, its primary focus is on delivering value through continuous improvement rather than scaling up rapidly.

Choosing the Right Framework

Ultimately, the choice between DAD and SAFE depends on the organization’s size, complexity, and goals. If you are a large enterprise with multiple teams working on complex projects, then SAFE may be the better option for you. It provides a prescriptive approach that can help teams work together more effectively and achieve success at scale.

However, if your organization is smaller or has less complex structures, then DAD may be a more suitable option. Its flexible approach allows teams to tailor their approach based on their specific needs and context. This can help organizations adopt agile practices without having to change everything overnight.

Meet the Disciplined Agile Coach: Mentoring Organizations on Software Development

Agile software development has become a popular methodology in recent years, as it allows teams to work collaboratively and adapt to changes quickly. However, implementing agile principles can be challenging for organizations that are used to traditional project management practices. This is where a Disciplined Agile Coach comes in, providing guidance and support for teams looking to optimize their software development processes.

Guiding Teams in Implementing Lean and Design Thinking Principles

One of the primary roles of a Disciplined Agile Coach is to guide teams and team members in implementing lean and design thinking principles. These principles help teams identify waste in their processes and focus on delivering value to customers. By adopting lean principles such as continuous improvement, visual management, and flow efficiency, teams can reduce lead times and improve quality.

Similarly, design thinking principles encourage teams to focus on the needs of users when designing products or services. This involves empathizing with users, defining problems from their perspective, ideating potential solutions, prototyping ideas, and testing them with users. By incorporating these practices into their software development processes, teams can create products that better meet the needs of their customers.

Co-creators of Disciplined Agile Delivery (DAD)

Disciplined Agile Delivery (DAD) was created by Mark Lines and Scott Ambler as an extension of agile methodologies such as Scrum and Kanban. DAD provides a framework for organizations looking to scale agile practices across multiple teams or departments. It incorporates elements of lean thinking, design thinking, DevOps practices, and governance frameworks to provide a holistic approach to software development.

Optimizing Software Development for Developers & Product Owners

A Disciplined Agile Coach helps developers optimize their workflows by identifying bottlenecks in their processes and suggesting improvements.
