Understanding their needs

To make sure we had a full appreciation of their requirements, we maintained close liaison with key stakeholders from the beginning and throughout the project life cycles, via regular calls, Teams meetings and site visits. A dedicated Project Manager was appointed at site to drive and report on progress. We maintained open lines of communication and stayed agile to the needs of the projects. These were the foundations of our success.

Identifying the challenges

The main challenges in the process were:

  • Proterra required a specialist partner for niche automation engineering resources.
  • They needed a partner to manage the on-site team effectively to meet project objectives.
  • Integration with Proterra’s staff on-site was crucial for consulting and resolving challenges.
  • Talos needed to collaborate seamlessly with Proterra’s staff to address issues during the project.

Our bespoke staffing solution

We supplied a core team of known and trusted engineers, starting with our Project Manager, and supplemented with the best available controls and electrical talent available as the projects peaked and troughed.

Delivering additional value

In addition to the above, we also delivered:

  • Provided constant project reviews to ensure progress and adaptability.
  • Adjusted Statements of Work (SOWs) to align with customer requirements and project goals.
  • Maintained consistency by retaining the same Lead Project Manager on-site throughout the project duration.
