No longer my sub team
Basically, there are 2 solutions to this problem. Method A is quick and easy but there is no way of tracing back the changes if required. Method B takes more time and effort to do but is tracable if required.
In the past, we would choose method B so that if there is an error or queries, we can still trace back the changes easily. So I told the user that we should use method B. As I'm no longer in my previous sub team, I forward the email to the new sub teamlead for him to take action.
But he came back to me and said that we should be using method A instead of B. Giving many reasons like method B is unpredictable etc etc. Hello, we've been doing method B in the past. There isn't any problem.
Been telling him that method A is near impossible to trace if there is an error or query, but he insist that it is possible.
After 5 minutes of discussion, I decided to take a step back. No point arguing when he doesn't seem to listen. If he decided to use method A, so be it.
After all, its no longer my sub team. If there is a mess, it will not be me clearing up. So why I bother so much? I've already advice you that method B would be better. Its up to you to decide which one to take.
Method A lor.... up to you. None of my business anyway.
