EDF – STERIA

TAMARIS project

The Tamaris project aims to create a programming platform and to carry out emergency interventions and repairs. The beneficiary of this project is ERDF (Electricité Réseau de Distribution France), a subsidiary of EDF. Steria has been entrusted with the implementation of this project.

Total project duration : 5 months
The total cost of the project was 100 man.days

Details of the project :

Problematic

In view of the liberalisation of the electricity market and to homogenise the existing fleet of electricity meters (more than 23 models), ERDF designed the new smart and communicating meter named Linky. It will be deployed in all households in France between 2012 and 2017. A major IT infrastructure is required to complete this long deployment operation.

The main objectives of the project were :

Carry out real-time planning of work orders
Enable the 6,000 network technicians in the field to enter service information on a lightweight terminal and instantly send the information to the central system.

Mission statement

Join the “Mobility” team that is supposed to develop the on-board tool for technicians in the field. Tasks carried out during the mission:

Study of needs and constraints
Business concept modeling
Technical design
Setting up the technical and software architecture of the system to be developed
Realize functional mock-ups for the validation of technical concepts
Development of the application’s screens in Agile Methodology
Unit and integration tests
Performance optimization
Investigations and correction of anomalies
Packaging and deployment on test and acceptance platforms

Organization

Integration of a Steria team of 4 people.

Main characteristics of the client

ERDF, a wholly-owned subsidiary of EDF, is the operator of the public electricity distribution network on 95% of mainland France. Its 35,000 employees operate, maintain and develop almost 1.3 million kilometres of network every day.

Business processes covered by the solution

Work order management
Bi-directional real-time communication with the central system

What were the most difficult features to implement ?

Among the most complex functionalities implemented by the speaker we can count :

Ergonomic user interface design for a small screen size (QVGA: 320×240 pixels)
Necessary adaptations for interfacing with the central system (use and modification of an existing exchange brick)

Technical platform elements

Software package, software or development languages used
