Agile methods have been dominating the software development domain in the last decade, and they have proven to be successful for managing and executing software development projects, which are considered as innovative knowledge work as opposed to task work projects founds at other domains such as manufacturing.Agile teams usually focus on quick and short-âterm improvements identified either through daily collaborations or through periodic vehicles like retrospectives. Lean Software Development (LSD) is an agile framework based on optimizing development time and resources, eliminating waste, and ultimately delivering only what the product needs.

If you have people who are just going to say, “my job is done, I’m not going to think about it, I’m not going to give my consideration to the full picture”, it’s not a good fit. The first is releasing sloppy code for the sake of speed. This is the approach that revolutionized factories in the XX century, the approach that made mass-production possible. Once that is determined, the team can design the right work approach. When developers feel pressured to deliver at all costs, they release code that may or may not meet quality requirements.

Leanâs major concept is about reducing waste, meaning anything in your production cycle that is not adding value to the customer is considered waste and â¦ Lean can help organizations develop objective ways to sequence and assign projects. Lean software development is an iteration methodology initially developed for the manufacturing industry to optimize production and avoid waste. There are no two software development projects that are identical. The second book of Mary and Tom Poppendieck is called âImplementing Lean Software Developmentâ. Eliminate waste The key element of practicing Lean is to eliminate that does not add value. The Lean principle of Respect for People is often one of the most neglected, especially in the fast-paced, burnout-ridden world of software development. It requires buy in from stakeholders and commitment to the concept. The question isnât why teams want to deliver fast, but rather, what slows them down. The evolution of these concepts will help you manage the waste at different levels. This can be done by using any combination of the following tools: This Lean development principle is easily misused. Maybe there is nothing. If you find that out later on in the process, you end up with budget overruns etc. Instead, it finds its roots in lean manufacturing. As the antidote to suboptimization, optimizing the whole is a Lean development principle that encourages Lean organizations to eliminate these sorts of vicious cycles by operating with a better understanding of capacity and the downstream impact of work.
