  • Big Ball of Mud, Still the Most Popular Software Design

    Big Ball of Mud, is a code jungle which is haphazardly structured, sprawling, sloppy and connected by duct-tape. Over the years we have been introduced to various guidelines such as SOLID, GRASP and KISS amongst age old, high cohesion and low coupling to deal with this Mud.

  • Monetizing the Technical Debt

    Most Agile teams recognize the evils associated with technical debt. Just like a financial debt, the technical debt incurs interest payments. These are paid in the form of extra effort required to maintain and enhance the software. Most Agilists recommend repaying the technical debt as early as possible. However, most Agile teams fail to monetize the technical debt.

  • Temporary Code, Sustainable Code and Everything in Between

    There is code which is well tested, well re-factored and built to last. There is also code which is planned to be thrown away in a few days. Between these two extremes, there is a lot of gray area. The code in this gray area is written with the presumption that it would be cleaned up later but is never done.

  • To Comment or Not to Comment

  • Continuous Deployment, In Practice

    Continuous deployment has gained a recent buzz in the Lean-slanted "eliminate work-in-progess" movement.

Ash Maurya helps to fill this gap by describing his experience with making it happen at his company.

  • Stabilization Sprints, A Necessary Evil or Pure Waste?

    Stabilization sprints are an additional number of sprints added to the end of the normal development cycle before shipping the product. As the name suggests, they’re usually added to shake down the product one last time and drive the last of the bugs. Do they belong in Agile environment or should "Done" be enough.

  • Dissecting Technical Debt

    The term "technical debt" was coined by Ward Cunningham. It describes the obligation that a development team incurs when it chooses a design or construction approach that is easy to implement in the short run but has a larger negative impact in the long run. Agilists provide their view point on what should be considered a technical debt and how it could be classified.

  • Software Debt Adds Up to Substantive Costs

    In a recent article entitled “Continued Delivery of High Values as Systems Age”, Chris Sterling discusses the concept of Software Debt – “Software debt accumulates when focus remains on immediate completion while neglecting changeability of the system over time.” Software Debt goes beyond technical debt an encompases a variety of aspects that impact on the ability to deliver value.
