I have been using the solution for five years.

I have been using it for a longer period of time. It has been in use for over 25 years. So, I've been using it since 1998.

We've used the solution for 20 years. It's not that easy to change BI tools - especially after 20 years. 

I've been working with this solution since last year.

I have used it since 2010, and eventually, I moved onto doing implementations.

I've used it for four to five years.

I am currently working at an oil company in Nigeria and the Infor SunSystems and PM suite has been used at this company for around two years. They are using Infor PM Q&A version 10.1 including Q&A XL, and Executive & Alert - installed alongside Infor 10 SunSystems Financials system.

Personally as a SunSystems/Q&A consultant I have used the product for 20 years in various iterations.

I have been using it for the past four and a half years.

I've used this solution for one year.

I've used it for more than five years.

I've used is for almost four years.

I used it for six months of deployment and then one year of support and developments.
