If you want to build software the lean, agile way, then this blog post is for you. In this post, we’ll take a look at what lean software development is, the principles of lean and agile software development, and how you can apply these principles to your own software development process. By the end of this post, you’ll have a good understanding of how to build software using lean and agile methods.

Lean Software Development.
Lean software development is a set of principles and practices for developing software in a more efficient and effective way. The goal of lean software development is to minimize waste and maximize value.
There are three main principles of lean software development:
1) Eliminate waste
2) Build quality in
3) Deliver value faster
The main practices of lean software development are:
1) Continuous improvement
2) Incremental delivery
3) customer involvement
4) early feedback.
The Agile Manifesto.
What is the Agile Manifesto
The Agile Manifesto is a document that outlines the key principles of Agile software development. It was created by a group of software developers in 2001 as a response to the traditional, waterfall approach to software development. The Manifesto consists of four key values and twelve key principles.
The four key values are:
1) Individuals and interactions over processes and tools;
2) Working software over comprehensive documentation;
3) Customer collaboration over contract negotiation; and
4) Responding to change over following a plan.
The twelve key principles are:
1) Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2) Welcome changing requirements, even in late development. Agile processes harness change for the customer’s competitive advantage.
3) Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4) Business people and developers must work together daily throughout the project.
5) Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
6) The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7) Working software is the primary measure of progress.
8) Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9) Continuous attention to technical excellence and good design enhances agility.
10) Simplicity–the art of maximizing the amount of work not done–is essential. 11) The best architectures, requirements, and designs emerge from self-organizing teams . 12) At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.The Principles of the Agile Manifesto
The principles of the Agile Manifesto are based on four key 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.
These values are reflected in the twelve key principles of the manifesto, which state that businesses should prioritize satisfied customers through early and continuous software delivery; welcome changing requirements, even in late development; deliver working software frequently; work together daily throughout the project; build projects around motivated individuals and trust them to get the job done; use face-to-face conversation as the most efficient method of conveying information; make working software the primary measure of progress; promote sustainable development so that sponsors, developers, and users can maintain a constant pace indefinitely; continuously attend to technical excellence and good design to enhance agility; simplify whenever possible; let self-organizing teams emerge naturally; and reflect regularly on how to become more effective, then tune and adjust behavior accordingly.
Lean and Agile Software Development in Practice.
Applying Lean and Agile Principles to Your Software Development Process
In order to build software the lean, agile way, you need to apply lean and agile principles to your software development process. Some of the most important lean and agile principles include:
1) Eliminating waste: Lean software development is all about eliminating waste in the software development process. This means identifying and removing anything that adds cost but doesn’t add value from the process. Common sources of waste in software development include unnecessary features, rework, inefficient processes, and delays.
2) Creating value: The goal of lean software development is to create value for the customer. This means delivering working software that meets their needs as quickly and efficiently as possible.
3) Continuous improvement: Lean and agile software development are all about continual improvement. This means constantly looking for ways to optimize the process and improve quality. It also means making sure everyone involved in the process is always learning and growing.
4) Empowering team members: In order to be successful, lean and agile teams need to be empowered to make decisions and take ownership of their work. This means giving them the authority to make decisions, providing them with adequate resources, and creating an environment where they can openly communicate with each other and with stakeholders.
If you want to build software the lean, agile way, then you need to focus on two things: lean software development and the agile manifesto. These two concepts are the foundation of lean and agile software development practices.
Lean software development is all about minimizing waste and maximizing efficiency. The principles of lean software development include eliminating waste, amplifying learning, delivering value early and often, embracing change, and respecting people.
The agile manifesto is a set of 12 principles that guide agile software development. The principles of the agile manifesto include 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.
To apply lean and agile principles to your software development process, you can use scrum or kanban. Scrum is a Lean and Agile software development process that emphasizes team collaboration, customer feedback, and continuous improvement. Kanban is a Lean and Agile software development process that emphasizes visualizing workflows, limiting work in progress, and continual delivery.
No matter which Lean and Agile software development process you choose, the important thing is to focus on delivering value to your customers quickly and efficiently.
