- The Agile Manifesto was created in 2001 by a group of software developers who sought to improve traditional waterfall development methods
- It consists of four core values: individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan
- The manifesto also outlines 12 principles that guide agile practices, such as welcoming changing requirements, delivering working software frequently, and reflecting regularly on how to become more effective
Toyota production system
- The Toyota Production System (TPS) is the foundation of lean manufacturing principles, developed by Toyota in the mid-20th century
- TPS aims to minimize waste and optimize production flow by implementing practices such as just-in-time inventory management, continuous improvement (kaizen), and respect for people
- The success of TPS in the automotive industry led to the adoption of lean principles in various other sectors, including software development and innovation management
Core tenets of agile
Iterative development
- Agile emphasizes iterative development, where products are built incrementally in short cycles (sprints) rather than in a single, linear process
- Each iteration involves planning, designing, developing, testing, and reviewing a small set of features, allowing for frequent feedback and adjustments
- Iterative development enables teams to deliver working software early and often, reducing the risk of building the wrong product and adapting to changing requirements
Self-organizing teams
- Agile teams are self-organizing, meaning they have the autonomy to determine how best to accomplish their work without heavy top-down management
- Team members collaborate closely, share knowledge, and take collective responsibility for delivering high-quality products
- Self-organizing teams foster creativity, motivation, and a sense of ownership, leading to better problem-solving and decision-making
Customer collaboration
- Agile prioritizes close collaboration with customers throughout the development process to ensure that the product meets their needs and expectations
- Customers are actively involved in providing feedback, clarifying requirements, and validating the product at each iteration
- This collaboration helps align the team's efforts with customer value and reduces the risk of building features that are not useful or desired
Responding to change
- Agile recognizes that change is inevitable in complex projects and embraces it as an opportunity for improvement
- Teams are prepared to adapt their plans and priorities based on new information, changing market conditions, or evolving customer needs
- By being responsive to change, agile teams can deliver more relevant and valuable products, even in dynamic and uncertain environments
Key practices in agile
Scrum framework
- is one of the most popular agile frameworks, providing a structured approach to managing and completing complex projects
- It involves roles (, , Development Team), events (Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective), and artifacts (Product Backlog, Sprint Backlog, Increment)
- Scrum emphasizes transparency, inspection, and adaptation, with regular meetings and deliverables to ensure the team is aligned and making progress towards the goal
Kanban boards
- is a visual workflow management method that helps teams visualize and optimize their work processes
- Kanban boards display work items (usually represented by cards) in columns that represent different stages of the workflow (e.g., To Do, In Progress, Done)
- By limiting the amount of work in progress and making the flow of work visible, Kanban helps teams identify bottlenecks, manage capacity, and continuously improve their process
Sprints and iterations
- Sprints (also called iterations) are the core of agile development, representing fixed time-boxes (usually 1-4 weeks) in which a set of work is planned, executed, and reviewed
- Each sprint begins with a planning meeting to define the sprint goal and select items from the product backlog to work on
- The team collaborates daily to complete the planned work, and at the end of the sprint, they demonstrate the working product increment and reflect on their process to identify improvements for the next sprint
User stories
- are a way to capture and communicate product requirements from the perspective of the end-user
- They follow a simple template: "As a [type of user], I want [goal], so that [reason]" (e.g., "As a customer, I want to be able to save my shopping cart, so that I can continue my purchase later")
- User stories help the team focus on delivering value to the customer and provide a basis for estimating, prioritizing, and planning work in each sprint
Continuous integration
- Continuous integration (CI) is a practice of frequently merging code changes into a shared repository and automatically building and testing the software
- CI helps detect and resolve integration issues early, reduces the risk of conflicts and errors, and ensures that the software is always in a releasable state
- Agile teams often use CI tools (e.g., Jenkins, Travis CI) to automate the build, test, and deployment processes, enabling faster and more reliable delivery of software
Lean principles overview
Eliminating waste
- Lean focuses on identifying and eliminating waste (muda) in all its forms, including overproduction, waiting, unnecessary motion, defects, and excess inventory
- By streamlining processes and removing non-value-adding activities, lean helps teams reduce costs, improve efficiency, and deliver more value to customers
- Examples of waste in innovation management include unnecessary features, delays in decision-making, and rework due to poor quality or changing requirements
Continuous improvement
- Lean promotes a culture of continuous improvement (kaizen), where everyone in the organization is encouraged to identify and implement small, incremental improvements every day
- This involves regularly assessing processes, identifying opportunities for optimization, and experimenting with new ideas and solutions
- Continuous improvement helps teams adapt to changing conditions, learn from failures, and strive for excellence in all aspects of their work
Respect for people
- Lean recognizes that people are the most valuable asset in any organization and emphasizes respect for their knowledge, skills, and contributions
- This involves empowering employees to make decisions, providing them with the necessary tools and training, and fostering a culture of trust and collaboration
- By respecting and engaging people, lean creates an environment where innovation can thrive, and continuous improvement becomes a shared responsibility
Delivering customer value
- Lean focuses on delivering maximum value to the customer by understanding their needs, preferences, and pain points
- This involves defining value from the customer's perspective, mapping the value stream to identify and eliminate waste, and creating a smooth flow of work to deliver value quickly and consistently
- By aligning all activities with customer value, lean helps teams prioritize their efforts, make better decisions, and create products that truly meet customer needs
Applying lean in agile
Minimum viable products
- is a lean concept that involves delivering a product with just enough features to satisfy early customers and gather feedback for future development
- Agile teams often use MVPs to test their assumptions, validate customer needs, and iterate on the product based on real-world usage and feedback
- By focusing on delivering MVPs, teams can reduce waste, minimize risk, and ensure that they are building the right product before investing too much time and resources
Fail fast approach
- Fail fast is a lean principle that encourages teams to experiment, learn from failures, and adapt quickly to new information or changing conditions
- In agile development, this involves delivering small increments of working software, gathering feedback, and making adjustments based on what works and what doesn't
- By embracing failure as a learning opportunity and iterating rapidly, teams can reduce the cost of mistakes, improve their processes, and deliver better products faster
Reducing work in progress
- Lean emphasizes reducing work in progress (WIP) to minimize waste, improve flow, and increase throughput
- In agile teams, this involves limiting the number of items being worked on simultaneously, focusing on completing tasks before starting new ones, and avoiding multitasking
- By reducing WIP, teams can identify and address bottlenecks, improve collaboration and communication, and deliver value more consistently and predictably
Benefits of agile and lean
Increased adaptability
- Agile and lean practices enable teams to adapt quickly to changing requirements, market conditions, or customer needs
- By delivering small increments of working software and gathering frequent feedback, teams can course-correct and adjust their plans based on new information or insights
- This adaptability helps teams stay relevant, competitive, and responsive in dynamic and uncertain environments
Faster time to market
- Agile and lean practices help teams deliver working products faster by focusing on iterative development, eliminating waste, and optimizing the flow of work
- By delivering MVPs and gathering early feedback, teams can validate their assumptions and prioritize features that deliver the most value to customers
- This faster time to market enables teams to seize opportunities, gain a competitive edge, and generate revenue earlier in the product lifecycle
Higher quality products
- Agile and lean practices emphasize continuous testing, integration, and improvement, leading to higher quality products that better meet customer needs
- By involving customers throughout the development process and gathering frequent feedback, teams can identify and address quality issues early, before they become costly or difficult to fix
- The focus on delivering working software in each iteration also ensures that quality is built in from the start, rather than being an afterthought or a separate phase
Improved team morale
- Agile and lean practices foster a culture of collaboration, trust, and continuous improvement, leading to higher team morale and engagement
- By empowering team members to make decisions, share knowledge, and take ownership of their work, agile and lean create an environment where people feel valued, motivated, and committed to delivering their best
- The regular feedback loops and opportunities for reflection also help teams celebrate successes, learn from failures, and continuously grow and improve as a unit
Challenges with agile and lean
Organizational resistance
- Implementing agile and lean practices often requires significant changes to an organization's culture, structure, and processes, which can face resistance from individuals or groups who are comfortable with the status quo
- This resistance can stem from fear of change, lack of understanding, or concerns about loss of control or power
- To overcome organizational resistance, leaders need to communicate the benefits of agile and lean, provide training and support, and create a safe environment for experimentation and learning
Lack of upfront planning
- Agile and lean practices emphasize adaptive planning and responding to change, which can be challenging for organizations that are used to detailed upfront planning and fixed scope
- This lack of upfront planning can create uncertainty, ambiguity, and discomfort for stakeholders who want to know exactly what will be delivered, when, and at what cost
- To address this challenge, agile and lean teams need to establish trust with stakeholders, provide transparency into their progress and plans, and demonstrate the value of iterative development and continuous improvement
Difficult to scale
- Agile and lean practices are often easier to implement in small, co-located teams, but can be more challenging to scale across larger organizations or distributed teams
- This is because agile and lean rely heavily on face-to-face communication, collaboration, and rapid feedback loops, which can be more difficult to maintain as teams grow and become more dispersed
- To scale agile and lean successfully, organizations need to invest in the right tools, processes, and infrastructure to support distributed teams, and foster a culture of trust, transparency, and continuous improvement at all levels
Agile and lean transformation
Leadership buy-in
- Successful agile and lean transformations require strong leadership buy-in and support from the top of the organization
- Leaders need to champion the benefits of agile and lean, provide resources and funding for the transformation, and model the behaviors and values that they want to see in their teams
- This involves communicating a clear vision, setting realistic expectations, and creating a safe environment for experimentation and learning
Training and coaching
- Agile and lean practices involve new skills, mindsets, and behaviors that may be unfamiliar or challenging for team members who are used to traditional ways of working
- To support the transformation, organizations need to provide training and coaching to help team members understand and apply agile and lean principles and practices
- This can involve formal training courses, workshops, and certifications, as well as ongoing coaching and mentoring from experienced agile and lean practitioners
Metrics and measurement
- Measuring the success of an agile and lean transformation requires a different set of metrics and indicators than traditional project management
- Instead of focusing on outputs and deliverables, agile and lean metrics emphasize outcomes, value delivery, and continuous improvement
- Examples of agile and lean metrics include , cycle time, customer satisfaction, and defect rates, which help teams track their progress, identify areas for improvement, and demonstrate the value of their work to stakeholders
Continuous improvement culture
- Sustaining an agile and lean transformation requires a culture of continuous improvement, where everyone in the organization is encouraged to identify and implement small, incremental improvements every day
- This involves creating feedback loops, celebrating successes, learning from failures, and fostering a growth mindset that embraces change and experimentation
- Leaders need to model this culture by setting goals, providing resources, and recognizing and rewarding continuous improvement efforts at all levels of the organization
