“Response times divided by two or even three !”
Interview with Alexandre Bocquet, Operation Manager Sunzil ( EDF & Total Groups)

Subsidiary of the Total and EDF groups, Sunzil builds and operates solar power plants for professionals, local authorities and individuals. Located in overseas departments and territories (DOM-TOM) such as Mayotte, Guyana, la Réunion or la Martinique Island, the operations department of the company maintains more
than 750 photovoltaic generators.
In order to harmonise the maintenance processes across all territories, Sunzil has made the choice to get equipped with the Coswin 8i CMMS solution. A look back at the project, with the Operations Manager of Sunzil, Alexandre Bocquet.
A “paper” management of maintenance operations
« Sunzil has two main activities: construction and operation of photovoltaic installations. Within the operations branch, our mission is to carry out the maintenance of the equipment that we have installed on our behalf as power producer, or belonging to our clients.
Our teams are composed of engineers, maintenance managers as well as technicians carrying out interventions directly on site. Until then, the follow up of maintenance interventions was specific
to each territory and managed in a traditional way: the technicians had an intervention sheet to fill up and hand over. We had then to reread and enter them in the client’s file… It was a very timeconsuming
task for the teams and the efficiency was quite relative. That is why we have begun to look for a less constraining and more efficient solution.
The deployment project of a CMMS software solution has been running through my head for some times now. We have therefore decided to launch ourselves by probing the French Editors’ Market
The choice of Coswin for its functional coverage
« When writing a specification document, we began reviewing our objectives. We needed complete and powerful software that could integrate all the particularities of our activity. Indeed, the biggest challenge was to standardise processes through all our DOM-TOM agencies.
It involved managing automatically different time zones as well as to standardize the means for monitoring
the interventions specific to each territory. This harmonisation was intended to control the interventions planning and management of our material and human resources.
After auditing five editors, we chose Siveco Group and their Coswin 8i solution. The software gathered all the assets we were looking for: ergonomic, scalable, mobile and customisable. As we had anticipated, the implementation project, which was intended to be a real reorganisation of our processes, lasted nearly 18 months.
We jointly adapted the tool, set up users’ profiles, standardised and imported data. Then we integrated the solution in our information System and organised several training sessions.»
Benefits already visible after six months of use
« Coswin 8i has been operational for six months and we are already seeing the benefits. About fifty collaborators are using the solution: engineers, managers, technicians (sedentary or mobile) and are all working on the same tool and the same data.
Our intervention practices are therefore homogenised and our range of services are from now on codified regardless of the territory. We have rationalised interventions’ preparation in order to guarantee the interveners’ security. Now, thanks to Coswin Nom@d mobile solution, the operators fill out their interventions’ files on their tablets. Each intervener has his own login name and can provide the details of his maintenance operation directly in the software wherever he may be.
By adopting predictive maintenance, we guarantee to our maintenance technicians the good resources, the right means and adapted material as well as safety instructions. We benefit from supply security because Coswin 8i allows us to anticipate stocks fluctuations and delivery times for our orders. Eventually, we would
even be able to smooth the charges to manage our expenses at best.
Our clients are the first beneficiaries of this new organisation: response times have been divided by two or three. Formerly, it was difficult to have a global vision of all our actions. Priorities were badly defined and response times could go up to 48 hours. Today, we have a clearer idea of the emergencies and we can intervene almost in real time. »

Project objectives
