I assume most of you work with others in a team. Even if you are the data specialist and others work on different technologies, you still have a team. How long has your current team been together in this form? Have you had a stable team that might have grown, but the rest of the individuals and roles/responsibilities stay the same? Or has your team changed makeup, roles, responsibilities, or something else?
I don't see a lot of organizations that change their team structures often. There may be people who come and go from a team, but the core structure remains the same. Even when your company might reorganize a bit, often it's teams that shuffle between managers, but mostly remain the same. There certainly are exceptions, and some large orgs (Microsoft, Amazon, etc.) regularly shuffle lots of people around, but I'm not sure the teams change their makeup or their mandate much.
I was thinking about this as I read an article on knowing when to restructure your team. I won't recommend you read it as I think seems to imply restructuring technology teams will make them perform better and start meeting all the commitments that have been made. While I do think that a well-led team can perform better, restructuring your teams isn't likely to make them more efficient and productive. That being said, I do think the article raises some good questions about how you might evaluate your team.
There are certainly times when an IT team, whether in development or operations, might start to miss deadlines or may seem to work inefficiently from the outside. We are human, and humans can get complacent, or they might focus on tasks or work that they want to complete, ignoring work they don't enjoy. The latter might be things the business needs, and restructuring the team isn't going to fix that. Either the current staff has to be managed more closely to get them to focus on necessary work, or maybe different people should be assigned to those projects or tasks.
Just remember you work with humans, and they often struggle with change. Change might be necessary, but a little empathy helps us cope with the challenges and learn to work together in our new structure. If we don't have that, likely nothing gets better and we fall into old habits.
