ISSI has been a fantastic partner on the ETS project. Their technical aptitude as well as their customer service is exceptional. The project team is exceptional at communicating with the stakeholders of the project. They always follow up with the business units and are very customer-focused. The ETS project initially was a redesign for the MDEs TEMPO system that had an Oracle backend. ISSI identified a more cost-effective build with SQL as the new architecture. They were able to adapt to the changes and keep the project on time and within budget. The project team is professional and technically savvy. I had a lot of confidence in the team from ISSI. The project had some changes that put a strain on the timeline. ISSI was able to deliver the project on time. ISSI has always been cost minded with the project funds. They have never overspent and if any of the costs were going to be higher for a particular sprint they were able to communicate it to the stakeholders and work to keep the project budget on target.
