At this post I’ll talk about a funny connotation which I’ve made about software deliverable1, our expectations with customer and the maintenance cost after that.
At software projects, we’re facing situations like the connotation above. A customer wants a simple change or request, not so simple at the majority of requests, to avoid lose a customer, tries to embrace the request and the final piece at some times is bad defined and with a tight deadline.
The bad definition per se causes a lot of trouble, because when a developer convert the rules into code, probably the side effects wasn’t measured or known and most of the time it’s a waste of time.
Another problem to this “simple requests” is the poor design (here, design is about all the layers needed to deliver the request, from UX to frontend, backend and infrastructure to solve). But, why are there a poor design with so simple requests? Because, we’re defining the deliverable to be a “Grilled ham and cheese” and not a double burger, the structure will be a lot simpler, tied and will struggle to evolve.
The customer itself doesn’t compreheend what he want clearly, but certainly he don’t want any features (e.g. a salad) delivered to disguise the main request and even less a new deadline.
Because of all the misunderstanding about the request and the unhappy customer, the deadline proposed was tight and the request again, delivered after time with a bad experience (bugs, slow and other sort of issues). And the customer will be “content” with that, until he goes away.
The maintenance cost probably will be high, because now the product has a new feature which doesn’t satisfying the customer who requested it, the product team must support it, costing time from all the peers involved. Any time someone wants to fix or improve the feature, he/she will spend more time and more time to figure out what is going on.
Maybe a full rewrite and talk to the customer is more appropriate than patch up a thing which born broken and faulty, there are a lot of technical debts that a small change could even causes more trouble. A full rewrite resolve most of them, but is has some cost and delay other deliveries too, the previous “fast” move to keep the customer happy add an extra step to evolve with their debts.
Sometimes it’s better to say no to a customer and reject a simple request on a software development world, to say yes and deliver a mislead or broken feature. Therefore, with more plan and analysis is far better to deliver even a simple but more robust, correct, focused customer deliverable with room to grow is better and avoid trouble.
