The number of staff that we need for the implementation of the solution depends on the scale of the environment, but you certainly need a couple of engineers for the support and management. IBM has a set amount of people that are required.

We use DevOps tools for deployment, so it doesn't take much time.

We implemented the solution in-house. 

We implement the solution for our clients. We also provide maintenance every quarter to give support to the production environment. If the client needs extra features, the project is more complex and takes more development time. 

We implemented it in-house. It hardly takes any time; perhaps a day or two.

The only maintenance you need to be worried about is upgrading the patches, and you need to make sure that you apply those on time. We have two people who are responsible for the maintenance and administration.

We use a professional service to implement this solution.

We worked with consultants to implement the system. The solution is very consultant-friendly.
