Do developers still need UML?
Rafal Pienkowski Nov 19 '17
I'd like to know your opinion on whether UML is still needed in developer's daily work.
If you're curious why I'm asking about UML please read paragraph below.
I'd like to share with you why I've started thinking about usefulness of UML in everyday life.
I always knew "something" about an UML. I mean I know how to read and write basic diagrams. I'm personally that UML is very useful and I regret that I used it so rarely. I've read some books about solution designing with UML but you know that theoretical knowledge without practice began to be out of date.
So I've decided to take part in UML training. In my company I need to receive consent from my supervisor to take part in a training which has place during working hours. So I wrote an email to my supervisor (which is non technical) and asked him for consent. After few days I met him next to coffee machine I reminded him about my email. He told me:
I didn't forgot about your email. I'd like to ensure that you really want to take part in this training. I was thinking that nowadays nobody uses UML in daily work.
I was a little confused. In the same time my colleague (which is a developer too) started laughing and said:
Nobody uses UML.
That was a shock for me.
In my previous job every architect or designer used UML. I was working with UML too. I started to convince them why I'm thinking that UML is handy. Finally I received a consent to take part in this training :) and I hope the training will take place (minimum number of participant is required to start it).
As you can guess after lecture of previous paragraph I'm a big enthusiastic of UML. I think that UML if very useful in any kind of projects and especially in "big" projects they are something that you must have. I my opinion sequence diagrams help understand communication between two or more systems, use case diagrams are helpful to show all product's functionalities and plan future work, component diagram describes system's architecture and shows us a big picture, etc. These are just a few examples of using UML in daily work. I wish I could use UML more often.
In my opinion UML is a basic tool when you're working as a software architect. I wish I would be an architect so I'll learn UML anyway.
What is your opinion about UM? Is UML nowadays useless or useful? UML has become obsolete or just developers forget about it? Or maybe they exists some alternatives to UML which are more trendy and developers friendly?
I encourage you to share your opinion. Thanks in advance.
