I set up the solution in-house.

The solution is very simple to implement. It is similar to any other Windows application. There was no need for assistance.

The solution was implemented through an in-house team.

My colleague handled the implementation. 

Our implementation was done thought the vendor's team, and they were knowledgeable.

Only one person is required to maintain and support this product.

We outsourced implementation to one Microsoft technician skilled in setup and deployment of the solution and other Microsoft products such as SharePoint. 

I implemented through an in-house team. 

We have 10 engineers and managers that do the deployment and support of solutions.

I completed the setup myself.

Our in-house IT group pre-installed this solution for me. They also handle our support.

We have an internal IT team that performs all of the implementation procedures.

I did the implementation myself.

We did not have an explicit technical team from Skype for Business. We were using our local IT team of six engineers who was managing it in case of any issues.

I completed the installation myself.

We did the deployment of Skype for Business in-house.

I handled the implementation myself. I didn't need the help of any consultants or integrators.
