Let me begin this blog by relating one of my travelogue experiences. A known taxi driver drives me in his car to the Mumbai airport every week from the last 4 years. The car is about 8 years old, poorly maintained, and has tugged a good more than 300000+ kilometers; has by all means attained end of life, good enough to be dumped, and reap benefits from its scrap. As an enduring passenger, I have been containing the noisy tractor-like ride in his car due to my acquaintance with him and also believing his long false promise of a new car on its way to replace this one!
Week-on-week he comes with the same car and asks me if I noticed any evident difference in terms of travel experience. He would spend good amount of money replacing the old parts (like the tires, cars’ engine, AC, etc.) with better ones, beautifying it by a coat of varnish, etc.; the expenditure now almost exceeding the price of purchasing a 3-year-old second hand car. I honestly said a big NO each time he asked me and also wondered why he was investing on this old car when a new car according to him was arriving in the next 3 months!! This fetish behavior of patching the old car in anticipation of some miracle resulted in the loss of many good loyal customers (as they were fed up of the continued bad bumpy ride with no respite in sight in the form of a new car).
During one of my recent rough ride in the taxi, I realized how well this experience was analogous to what many organizations undergo during their agile journey. They have every agile practice in place; right mindset, best practices, roles/ceremonies/artifacts well defined coupled with communication, motivation, and empowerment. Even with such a robust agile framework, the teams/organizations lack agility to adapt to the changing customer requirements and deliver in a fast paced manner. Although in reality, organizations want to go fast (like any new car) by adopting agile but unfortunately are stuck with poorly maintained legacy codebase (like the old taxi). Any amount of replacement, beautification, superficial modification, or adopting new methodology/technique without addressing the deep-rooted problems might temporarily mask the real problem thereby breaking ‘transparency’, one of the 3 legs of empiricism (for scrum to be effective, each of these 3 pillars – transparency, inspection, and adaptation must stand and be supported).
When such projects are assessed, in all probability the hidden truth is that the organizations carry a herculean technical debt in terms of complicated and poorly maintained legacy codebase (just like the old car) with little or no attention to the engineering best practices, poor feedback cycles, no automation of unit./integration/regression, poor re-factoring and code reviews, etc. Based on the assessment findings, organizations need to perform a cost-benefit analysis and decide whether it makes sense to fuel such projects and take appropriate corrective actions immediately rather than wait for some magic to happen overnight in an organization/product by just adopting agile. If not, (like the taxi driver) organizations will fail to deliver/meet customer expectations, not be profitable, and loose out longstanding clients.
Therefore, for organizations in their attempt to keep pace with the competitive world it is not just enough to adopt agile methodology but should imbibe agility in their DNA. Varnishing an old car may give it a new look but the driving experience will remain the same; the same applies to organizations as well. In most cases, change/expected results may not be visible by just refactoring in bits and pieces (replacing the defective parts) but it may call for a complete eradication of the existing system (significant remarkable/dramatic one which would be a winning selling pitch for the organization; in the car analogy it is like buying a new car) and re-designing/re-writing the software to bring in a new vibrant spectrum.
Upon this cleanup and novel thought it is now time to think how to drive this concept (new car) effectively and efficiently! Adopting the rich agile ethodology along with adhering to solid engineering practices at this juncture would act as a fuel to propel the team/project/product/organization, accelerate, and drive towards success!
With the legacy issues addressed and best engineering techniques embraced, agile adoption certainly triggers agility and benefits the organization by delivering fast-paced, feature-rich, competitive, and user-beneficial products of significant business value!
