Duplication vs. Complexity
-
Rubber ducking here... ;) I'm working on a project that has a form which the user must fill in to submit a request. This form is used for various request types (+- 4) and shares common functionality (about 70%) between them. I have the choice of duplicating the form (UI and probably Logic) for the various request types or having one form with sections and columns that will be shown or hidden based on the request type. Either approach has pros and cons... Duplication: More maintenance if the common sections / logic change. Each request type's form will need to be updated. Complexity: Potentially many if else statements and more complex to understand and maintain e.g. changes in the common sections could break it for multiple request types. Which approach would you use? Maybe there is a hybrid approach? Edit: This is an Angular project, but I think the question applies to development in general.
Without knowing all the details, it seems I have to point the obvious: do whatever is easier for the user. Don’t let him wade through a long, complicated form just because it makes your code nicer. In the end, users’ time is more valuable than yours (at least because there are so many of them) and making them happy should be the most important thing. Without them your company would not survive and you’d be looking for a job.

:laugh: Sure, but don’t we have the same love/hate relationship with many in our own families. Seriously speaking, I’m a passionate advocate for a user centric point of view. I’ve seen too many programmers and ‘architects’ in their ivory tower looking with disdain to lowly users and forgetting our whole profession come in existence just to help these users. Can you imagine the people at MIT programming the Apollo guidance computer and saying “screw these astronauts, they are just some trained monkeys”?

I've successfully used a single dialog with all content and then injected the display and validation logic from a container. It should give you the best of both worlds.

Complexity is perhaps going to make it easier to extend. Duplication will in all likelihood make it easier to debug. I know it's the wrong answer from a software engineering point of view - but from the point of view of someone who spends a lot of time fixing defects on a huge code base I would go for duplication. I have seen a lot of code that makes use of inheritance and quite frankly I have found it to at times be something of a nightmare. Complexity is clever and is elegant but it can make tracking and fixing bugs a lot more difficult.

Inheritance and specialization. Maybe make the common sections into UserControls, etc.

Welcome Back Mr. Vilmos. ;) Long without seeing you. I hope everything is fine with you and your people.
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

Yeah, that's what I'm hoping to avoid.
That's when you're overdoing it. Put everything common in a base file that you inherit. Duplicate the rest.

A bit of a different idea: could you implement the common code in UserControls and classes so they have a well defined internal API?

I would also favour composition over inheritance where possible. So you could have a baseclass form that is very basic, then the implemented forms can perhaps use some form of builder to class to individually tailor those forms. Using composition may make it easier to see what each form is built from.

Every time I've re-used UI for multiple forms I've come to regret it. Ask yourself, who are the stakeholders for every form? Are they the same? Do they know if another form is changed? Do all forms change at the same time? If any of your answers is "no" then duplicate them, they look the same (for now), but are functionally different. I didn't and am now in a situation where one form is evolving while the other isn't and the amount of if-else's is too damn high! :sigh: Now, I only re-use specific elements or components on a page. Talking web (ASP.NET MVC and Razor Pages) and WinForms experience here (maybe your hybrid approach?).

A series of "user controls": no "duplication" - only reuse. Show / collapse based on context. The common "70%" is an obvious candidate for abstracting into a user control that becomes familiar; UI, business rules, or both.

ideally ... 1) define a generic base Form with common features/controls/logic all specific types will use. 2) define specific Forms that inherit from the base Form.

Some interesting comments in this thread - funnily enough almost all focussed on the technical details of one approach or the other rather than a general principle. To my mind, and after decades of coding in lots of environments, I (and this is only my personal opinion here!) always find a single codebase is overall easiest to maintain. Having multiple copies of similar, but not quite the same, code is just asking for trouble, especially as a generic logic error may not manifest in the same way in all duplicates. Careful structuring of the code, with - useful! - comments about what each section (however coded) is doing and why, will be much easier to keep working or amend than multiple similar versions. Especially so for someone unfamiliar with the codebase. Obviously for very small chunks of functionality this may not be true, but the more complex the process being modelled the greater the benefits of not creating multiple copies... All IMHO, of course, as I said!
