Everyone is developer in development team and not just a coder, a tester etc.

Scrum is very simple framework to develop complex software product in complex environment but hard to practice. But why? I am not going in details of why but wanted to highlight one problem about development team as per my understanding.

Development team means cross-functional and self-organizing team of developers. But who is developer? Isn’t it everyone who contribute to develop software? A coder, tester, dba, UI designer, content writer or business analyst? Now look at your team. Is it cross-functional? Yes you have because you have technician for all skills but are those technician are developers? May be not. There are just a coder, a tester, a dba, an ui designer and waiting for their skill related task. They are not working as developers with goal to develop software but they are just doing their task as per their skills.

Some of the key things that will help you to understand characteristics of development team. Assume L&D (Learning and Development Dept) is about to organize few trainings and announcing like below.

1st announcement “we are planning to have workshop for Scrum Developer so send your nomination”. You will find that only coder has subscribed for this workshop.

Another announcement “we are organizing Agile Testing workshop so send your nomination”. This time only tester will subscribe.

What reflect above? Team is still divided based on skills coding and testing. Tester feels everything related to testing is their domain and similarly coders feel all coding work is part of their work.

But in reality testers write code in order to test production code and coders write test to perform unit and integration test of code.

Another way of looking at it.

During sprint planning team has prepared below sprint backlog. What it reflects? There are tasks but those tasks are skills based and not component. Isn’t it bad way of creating task? If not? Then read below situation.

Assume there are 2 people Alex (coder) and Martha (tester) working on these 3 stories.

Alex done with coding part of story 1 in 2 days and Martha has started testing so what Alex will do next?

Most likely Alex will start working on coding part of story 2. But is it good? Why can’t Alex picks up other work from same story? Or why Martha was waiting for Alex to complete coding in order to start testing? Why can’t she pair with Alex to test in parallel or at least started testing APIs?

Many people asked me what’s wrong if Alex start working on coding part of story 2. Let’s see below situation.

Alex completed coding of 1st story and started coding 2nd story. Martha found a bug in story 1 so what she has to do? She reached out to Alex and wanted to discuss about it but Alex is busy and asked her to come later.

What Martha will do next? Most likely she will open a bug tracking tool and log newly found bug over there. Is it good? No but why Not? I will write about bug logging challenges separately but let’s focus on other aspect of it for now.

After a day Alex is done with coding of Story 2 and started looking into bugs those were logged by Martha. He identified route cause of a bug and framework level code changes needed in order to fix it. But that will also impact code that he has just completed for story 2.

What Alex will do? Good if he changes whatever needed in order to fix at route but it will generate rework and will delay delivery. Other option is shortcut to fix bug (patch work) so it should not have much impact on 2nd story code.

Majority of the time coders choose 2nd option because coders are very emotional about their code (just kidding). There are multiple reasons for choosing 2nd option but end result will be “Technical Debt”.

What can be done in order to avoid such scenario? Yes. 1st don’t create tasks like above but try to divide in component. Best is not to create tasks but still needed then divide in component. Work in pairing. Team should focus on finishing one that already in progress rather than starting new story.

Thanks for reading! If you have any query then reach out to me.
