The Principles of Lean Software Development

Sharing is caring!

The computer world, is taking over the world, due to the software development processes, which have been changing on a daily basis.

In today’s article, we are going to talk about, the lean software development methodology, in order to understand, how software development is done

The seven principles of lean software development methodology are: Eliminate waste, which helps software developers eliminate activities, which do not directly add value to the finished product.

The addition of unrequired features, project chum and crossing organizational boundaries which happens between stakeholders and development teams, are the three main sources of waste, in software development.

It is critical to reduce waste in development teams; therefore, development teams should be allowed to operate and self-organize, in a way, which would help them accomplish their tasks.

The reduction of scrap and preventing rework done late in the lifecycle of software development, are all the benefits that lean development can provide, to help a project to be improved.

Build in quality is another principle of lean development, and in it developers do not allow for defects to occur in the first place.

If it is not possible for the product to be developed without defects, the developers have to work in a way that a bit of work is done, it can then be validated, if there are any issues with the product then they should be fixed, and the product should be tested.

It is not effective to inspect after the damage has been done, and also to fix defect sometime in the future is a waste of time.

Test driven development is included in agile practices, which incorporates quality into the development of any product.

Create knowledge this is another principle of the lean software development, which stresses the fact that the development team, should learn what the stake holders want, and deliver on that knowledge.

Also development teams have a chance to act on what they’re doing, and then improve on their weaknesses.

Defer commitment is also a principle of lean software development and in it, development teams learn to not commit to irreversible decisions, until the last possible moment, so that the architecture of a product is flexible enough so that it can tolerate any changes.

Another principle of lean development is, Deliver quickly, which helps development teams deliver high-quality systems quickly.

A reliable and repeatable flow of work, can be established, by limiting the work of a team to its capacity; the number of points of functionality a team can deliver during an iteration, will reflect a team’s velocity to deliver, good quality products.

Teams are not demanded to do more than what they can do, instead organization that are effective ask teams, to self-organize and determine what they can accomplish.

When teams are focused on only delivering what they can on a regular basis, this will help them to stay focused, on continuously adding value to the product.

Respect people, another very important principle of lean software development, is to respect people, which suggest that thinking people who are engaged, always provide sustainable advantage.

So why disrespect them and treat them very unfairly, when that person deserves to be respected, regardless of the situation.

Project managers should not control development teams, instead they should motivate and enable them, so that the project is finished on time and with quality.

Optimize the whole, is another principle of lean software development and project managers get to look at the bigger picture, with this principle, in order to be effective at a solution.

High-level business processes, which individual projects support, have to be understood by project managers.

A completed product can be delivered to stakeholders, when programs of interrelated systems are managed.

The sole reason of an IT development team is to deliver business software, which are valuable to stakeholders, therefore, measurements must be put in place, to measure the delivery of good quality products.
