Software Development Methodologies: Lean Vs Agile Concept

Lean and Agile principles are one top notch topic floating around in the software development area, project management and organizational styles. We have previously blogged about website development lifecycle at Continuity in the above title link, one of the most discussed around subject has been selected for this time. Any developers here? Have a look at it and get a continuity in the go.

If you are researching for this topic in a dictionary, it defines clearly some features of the principle. Lean is defined as “thin and healthy, or containing little” whereas Agile as “having quick resourceful and adaptable character, or marked by ready ability to move with quick easy elegance.” From this we can infer that both methodologies do have some characteristics in common.

Agile and Lean: A Technological Definition

In the technology field, Agile methodology is known for the set of 12 principles and 4 values that can deliver complete guidance to the software development process, favouring flexibility, communication, collaboration, and simplicity, an all in one package. When coming to Lean principle in a professional arena, it lacks a clear cut definition and found to be less understood by them. Going in deep, the latter definition is a subtopic of the former in software development.

The Birth Of New Development Methodologies  

Both Lean and Agile were introduced due to the defect exhibited in plan driven models like waterfal. Inefficiency of these models were figured out by the developers by 1990’s and planned to shift to L & A because the outdated methodologies were unable to respond rapidly to the market demands, changing technology, or deliver bug-free software in a frequent manner.

Also, since evolution to an all new dynamic and tech savvy consumers has emerged, the developers sought to develop softwares which stands suitable for customer focussed approach. Also this technology brought a competitive advantage feature to the human hard work by favouring early and continued testing followed by project management and execution.

Lean Vs Agile Concepts

Lean development methodology was first suggested by by Dr. Robert Charette to furnish up organisation that had to widely depend on softwares. Agile Manifesto came out later which preserved the 12 principles of Agile concept. Mary and Tom Poppendieck was in hand of other works on software methodologies and all the remaining credits goes to her.

As mentioned above, you can see a wide similarity in the principles of Lean and Agile methodologies whereas 7 of them proposed by Poppendiecks is comparatively less in use by the developers, but do overlap with Agile Manifesto and Lean software development. Moreover, in L & A. there are elements common in both.

  • A quick respond to the customer needs.
  • Reaches early testing stage.
  • Delivers a continued approach to development.
  • MVP (Minimum Viable Product) style of development over heavy feature.
  • Manifests cooperation with a team, both inside and outside the company.



As we have seen in the opening paragraph, Lean methodology is less understood nowadays because of its broader applications and developers are onto the Agile process which can deliver softwares into the market in a more efficient manner. Notably, you can see that there are more of similarities in their respective principles than differences.

ATEES Infomedia, a reputed web application development company in Thrissur has crawled forward to move on to follow the L & A methodologies while creating softwares which needs to function appropriately and that delivers responsiveness to the web apps. in an efficient manner. Web application development in Kerala can only withstand and survive the competition by introducing latest advancements in the software development field, resulting in grabbing the most from the competitive advantage.
