The seven Lean principles are: Eliminate waste; Build quality in; Create knowledge; Defer commitment; Deliver fast; Respect people; Optimize the whole; In their book, Lean Software Development: An Agile Toolkit, Mary and Tom Poppendieck outlined how these Lean principles can be applied to software development. Generally this involves: 1: setting a quality standard for the software - it must do this, it should do that, it should not do the other, response times should be less than y, there will be no more than x bugs in each area. Avoiding unnecessary complexity will make your system more robust, easier to understand, easier to reason about, and easier to extend. Many of these principles relate to testing practices and ideals. Software development mainly considerate two points that are an emphasis on process and the quality of the software and process itself. By following these modern principles we can develop an efficacious software meeting all the needs of customer. It’s so obvious. Following are some concepts in software engineering that are based on the DRY principle -. Defect Density 3. Thus, the seven lean manufacturing principles can apply and be used in software development. It advises that we should build our functions/classes/modules in such a way that they are open for extension, but closed for modification. The DRY principle aims at reducing the repetition of code and effort in software systems. Software Development Tutorials written from the heart. They also rely on teamwork to get done. Dependability 5. Remember that whenever you add a new dependency to your project, or start using that fancy new framework, or create a new micro-service, you’re introducing additional complexity to your system.

Software Architecture: Principles and Practices - eLearning. The PMs collect requirements and track the progress of the project. Both have a single clearly defined responsibility. The SRP principle makes the code more organized. Although the term software architecture is used frequently in today's software industry, its meaning is not universally understood. EXTREME PROGRAMMING. Some obvious forms of waste include time spent building, analyzing, or designing features that won’t be used; or time spent supporting software and fixing bugs. It states that you should not introduce things in order to solve a future problem that you don’t have right now. You should split large interfaces into more specific ones that are focused on a specific set of functionalities so that the clients can choose to depend only on the functionalities they need. It stands for Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion.The acronym was first introduced by Michael Feathers and is based on Uncle Bob’s paper Design Principles and Design Patterns. Usability 4. The Open/Closed principle is a facilitator of the above idea. Now lets take a look at Software Quality factors. This is a set of principles used in various projects to improve the development process and increase its effectiveness. 1. The architect looks up the corresponding technical parameters in the matrix and tries to apply the listed innovative principles and architectural patterns that belong to them. If you believe that technical knowledge is all one needs to be a good software developer, you may be mistaken. Another way of putting it is this: there are many ways to fail at developing high quality software and only a few ways to succeed. Evolution starts from the requirement gathering process.
