Is it right to draw a new UI for the site every time?

Question

Design

Boiled!!!
It seems to me that my company has a very strange and not correct approach to creating websites.
Let's say for the main page, the designer has drawn a layout, it has modal windows (for example, with a feedback form). OK!
Made up! And another layout appeared, in which there are modal windows with registration, authorization, but of a different design.
Then another layout appeared, where there is a page with a photo contest, 2 more modal windows appeared there, different from the previous 2, but not similar to each other. It turns out we have 4 different window designs.
It's just as annoying as hell, at the moment when one could use one window for all (What would be the design of it bad then?), The designer takes and draws different ones all the time. Feeling like he is working with the project for the first time.
You look at some site made with the help of bootstrap and it has a single interface. The same modal windows, the same buttons, the same input fields, and so on. And the whole UI is in harmony.
Is it so? Or is it just my taste and color?

Answer 1

Forms, like other interface elements, must be unified and follow strict rules. Except for edge cases, when the price of changing the created rule is lower than solving a specific problem (for example, on the authorization form, the field names can be moved inside to fit the forms to the height of the laptop screen). This also applies to all related form elements and its mechanics, such as: headings, hints, errors, controls, etc.
This approach is fair both from the UI / UX / Product design side - the user uses the same interface element, the rules of behavior and the appearance of which he needs understand once.
So it is with the development and design of the interface in principle. Since the designer uses a ready-made set to design a new element, and the developer keeps one type of element. Which increases the speed of development.

Answer 2

Congratulations! I myself often encounter such a problem :)
Usually, in such cases I do it for a break, I type it myself, observing universality in the interface. If the designer starts to buzz, they say “why is the button here 50px high, when the layout is 48”, I begin to explain what's what. If the designer is adequate, he will understand his jamb and agree to a compromise - leave one of the options. If the designer is a dick and he doesn’t care about your arguments, then this means the following:
I think all these troubles are due to the fact that designers are fixated on the picture. It's strange, but we have very few specialists who are both good designers and at the same time still know how to program and make up a little. This is a completely different level.

Firstly, this question is not for us, but for the designer. There is a rule of communication: communicate. Call him! Now! :)
Secondly, maybe they think that the previous version of pop-ups and dialogs, the set of colors and fonts is not enough for users. And maybe they do it on a whim and subjectively, hoping that as a result something will change for the better. For this case, there are methods "A / B testing" and "Usability testing". Study it yourself and tell them how it is properly implemented.
Example:
before the pages of our Icons8 project became like this , they were like this. And how much effort was spent on the purchase page, registration and user profile - horror! And so on almost every page of the project, almost every button. The analysis is carried out using Google Analytics, User Testing and other means.

Answer 4

If in the end on the site of the collective farm, then it is wrong. But it may be that this is not just a page, but a whole section with a different design, then perhaps this is justified.
