We regularly see apparent issues as unworthy of dialogue. There isn’t a affordable product individual immediately that critically contemplates the opportunity of making use of crude waterfall to software program product growth. Waterfall is as useless as useless may be, and all people agrees on that.
The issue with ignoring the plain, although, is that we let our guard down. Issues we now have granted as gone can silently infiltrate our consolation zones, making the most of our dangerous habits to remodel themselves and take the forefront once more. Since nobody questions the plain, ghosts can hang-out us with out us even noticing.
From the tech bubble burst within the late 90s to the second burst we’re witnessing in 2022, waterfall has advanced from pariah to successor within the type of late-stage agile.
One can solely maintain the useless away if they’re prepared to debate the plain. That’s what I’m writing about immediately. From the basic dichotomy between the 2 approaches to how waterfall has infiltrated again in our lives, let’s dissect the plain in order that we will maintain our guard up.

Historical past of waterfall vs. agile
Earlier than we speak concerning the modern-day, let’s briefly talk about the historical past of each waterfall and agile for some further context.
Placing the “fall” in waterfall
First issues first, let’s take this out of the best way: waterfall undertaking administration is just not inherently dangerous. It’s an efficient and dependable software to handle initiatives that may solely ship worth when prepared, have low uncertainty, and have clear begin and finish dates.
Building, industrial engineering, and chemistry are a number of the industries that take large benefit of waterfall approaches.
I’m speaking particularly about software program waterfall undertaking administration. Again within the 80s and 90s that was all we had, however as time glided by, we found higher methods to ship software program.
A key issue for waterfall’s demise was the dot com bubble burst within the early 2000s. After a vertiginous fall of all monetary indicators of the tech trade, it hit all-time low in late 2002. Companies wanted a strategy to regain buyers’ belief by spending much less, delivering quicker, and guaranteeing ludacris paybacks on early investments.
The rise of agile
In 2001, a bunch of engineers and tech consultants acquired collectively and got here up with a nine-line doc that might change the whole lot. They saved engaged on what was left of the trade and their Manifesto not solely helped companies to remain afloat in a tempestuous market, but it surely additionally helped them bear outcomes ultimately.
The Agile Manifesto took the middle stage one yr later with the creation of the Scrum Alliance by, amongst others, two of the unique signatories of the manifesto. Time glided by and scrum turned the primary framework contender to waterfall. Encompassing the agile ideas to its core, scrum broke away from a hardline strategy to software program growth in favor of an iterative stance on worth supply.
When enterprise capitalists got here to grasp that firms with agile groups had better probabilities of delivering the outcomes they wanted, scrum shortly turned a requisite for tech companies to draw investments. It was a enterprise capitalist actually that took issues one step additional and coined the idea of the “lean startup.”
Eric Ries is a key determine within the development of what agile got here to be. His ebook, The Lean Startup, summarizes the whole lot that got here earlier than it and transforms what could be simply one other framework right into a administration philosophy. Corporations coached by him turned the primary unicorns and most companies that embraced the lean idea noticed their values skyrocket in a blink of a watch.
Product administration within the current day
Getting into the second decade of the twenty first century, agile, scrum, and lean are ubiquitous ideas contained in the tech trade. Waterfall is nothing however a distant reminiscence of what our ancestors would use to ship software program.
It’s “hip” and extremely rewarding to bear digital transformations, and even companies that don’t have anything to do with software program wish to embrace one of the best practices…that’s when the plain turns into harmful.
What’s essentially completely different?
Earlier than we begin exploring how waterfall corrupted late-stage agile tradition, let’s get our ideas straight. What does every of these approaches depend on?
A fast disclaimer, I received’t discuss frameworks, however tradition. Go away the manuals on the aspect, that is an evaluation of values that assist framework workout routines.
Waterfall basic values
Predictability
Waterfall is allergic to alter. From the conception stage, it’s essential to know the whole lot concerning the undertaking and it’s essential to be capable of see a transparent end line on the horizon. Waterfall initiatives have a triangle between scope, value, and time that, if wanted to alter, ought to occur inside value and time domains. Scope is at all times written in stone.
Management
Since scope is so tight, management have to be exercised to the microscopic stage. Managers have to be completely on prime of how issues are evolving in order that they’ll shortly react if one thing appears to be straying away from the unique plan.
Hierarchy
From the hierarchy of processes to the hierarchy of personnel, management can solely be exercised inside an atmosphere the place roles are fairly nicely outlined and accountability is centralized round these few who’ve a birds-eye view of the undertaking, normally higher administration.
Construction
Lastly, for hierarchy to exist, you want a construction and somebody answerable for retaining it up. Specialists are beams that ship restricted by their obligations, whereas pure administration figures are bolts and nuts accountable for retaining the entire thing collectively. The “specialists babysitting” mindset.
Agile basic values
Adaptability
Agile presumes that it’s not possible to manage all doable outcomes beforehand and that surprises will not be a matter of if, however when. The extra adaptable a undertaking may be whereas nonetheless delivering related worth to the consumer, the higher.
The “responding to alter over following a plan” line of the Manifesto represents this.
Horizontality
A undertaking can solely be adaptable if it lets go of the “command and management” mindset. People contained in the group ought to have the liberty to react as they see match at a second’s discover, and so they shouldn’t be afraid of doing so attributable to potential punishment or constraints.
This specific worth is translated by the “people and interactions over processes and instruments” line.
Collaboration
The place does the restrict between horizontality and chaos lie? An agile system can not exist exterior of a collaborative atmosphere. This takes into consideration the specialists, after all, but additionally the purchasers. An ever-changing atmosphere calls for that, regardless of any change of plans, the shopper feels assured in you to at all times have their finest pursuits in thoughts.
The “buyer collaboration over contract negotiation” line of the Manifesto interprets this worth.
Supply
To not say that agile doesn’t have a construction, it does. Scrum is essentially the most well-known of all of them and serves the undertaking, not the opposite approach round.
The target of any agile group is to ship worth to its buyer, to not do issues the suitable approach. If issues are executed in an unorthodox style however they work, that’s excellent. The top purpose issues greater than the journey.
The “working software program over complete documentation” line of the Manifesto interprets this worth.
Discovery
This fifth worth has no counterpart on waterfall and isn’t current within the Agile Manifesto. Of the entire lean contributions to agile tradition, that is an important one. Based mostly on the truth that we’re in an ever-changing actuality and that nobody is aware of higher than anybody else, with the ability to fail and be taught with that’s the quickest strategy to establish what’s value delivering.
The primary 4 values could be utilized to initiatives and merchandise alike, but it surely’s this fifth one which differentiates one from the opposite. A product is a dwelling factor that’s evolving with out a clear endgame in entrance of it. Discovery is as vital for a product as respiration is for us.
How agile is turning into waterfall
To cite Aristóteles closing argument on Metaphysics, ebook X half 10:
Issues which differ in variety are farther aside than these which differ in type
I do know Aristóteles was not what you had been anticipating to search out right here, and I received’t elongate myself on this. My level right here is that regardless of their variations, agile and waterfall are considerably interchangeable and, to some extent, the identical. Waterfall and agile tradition are completely different types of managing software program initiatives, however they’re product of the identical constituent idea: individuals managing individuals.
The values we lined, alternatively, will not be interchangeable. They’re completely different in variety, they’re certainly the quintessential distinction between agile and waterfall. Following the scrum information by the ebook, having squads, agile coaches, dailies, and meetups would possibly make you present up as agile, however except your values are aligned with the Manifesto, you’re simply dressing waterfall as agility.
That is exactly the state of affairs we now have been witnessing in the previous couple of years. As increasingly firms see the outcomes of sturdy agile tradition creating unicorns and trade juggernauts, extra of them desire a fast strategy to execute digital transformation. What occurs is that they begin practising agile, however maintain the waterfall values of management with an absence of flexibility and hierarchy.
Even worse, for the reason that variety of efficiently remodeled firms is approach smaller than those that simply fake to have transitioned, increasingly individuals haven’t any expertise with agile values, main them to consider that doing agile with waterfall values is completely regular.
Product individuals grow to be keepers of the scrum construction, roadmaps grow to be unalterable scope traps, engineers are restricted by being boxed beneath a enterprise hierarchy, and collaboration offers house for management as managers get increasingly insecure with how little company they’ve over what’s being delivered.
Little by little, agile tradition dies by the values, whereas waterfall resumes trade management utilizing the newest frameworks as hosts: SAFe, late scrum, Agile PMI…
What’s the drawback?
Regardless of what the above arguments would possibly entail, there isn’t a battle for the soul of the trade occurring. This romantic view of proper vs. improper or good vs. evil has no house on this debate. The dialogue is far more pragmatic: which set of values will get you essentially the most cash with the least headache?
The reply could be completely different relying on whom you ask it.
Monumental firms would possibly discover it arduous to keep up a horizontal, adaptable tradition because it has so many shifting elements. Money and time spent on making an attempt to copy a startup rulebook inside your decades-old enterprise with hundreds of staff is a drain that can in all probability bear no outcomes.
Alternatively, founding a disruptive digital enterprise the place all choices should undergo you first and the one legitimate imaginative and prescient is yours, in all probability means you might be in for a catastrophe in the long term.
The issue is just not doing one or the opposite, having this or that set of values. The issue is that the blurred strains do an ideal deal to homogenize the market, placing nimble startups and gigantic firms inside the identical bucket.
Enterprises make investments a fortune in making an attempt to grow to be what they probably can’t be, whereas recent companies have to develop quick earlier than they’ll begin to train correct management inside their construction. Everyone spends more cash to attain the identical outcomes.
When capital is obtainable for affordable available in the market, no huge deal, however when it turns into scarce, issues begin to break.
It may not be a coincidence that waterfall values had been dominant earlier than each of the tech bubble bursts…
Conclusion
Waterfall vs. agile is something however an apparent debate. There are such a lot of nuances to it that summarizing the whole lot in wanting 2000 phrases is sort of a sin.
Nonetheless, I hope this has been a dialog starter for you and your friends. That you could assess by yourself which values your group or your organization stands by and the way they’re affecting your job.
Waterfall tradition is just not improper, but it surely’s context-dependent, identical to agile. Giant and sophisticated mechanisms profit from a waterfall strategy, and in the event that they wish to grow to be extra agile, they need to maintain it a aspect undertaking. Smaller and youthful companies ought to take issues at their very own tempo, be horizontal, and deal with delivering worth. Go away construction and management for the long run, once you grow to be massive and sophisticated your self.
If you wish to know extra about how legacy firms can take leverage of agile values, I extremely advocate the ebook Exponential Organizations by Salim Ismael.
