IN 2020

Joint project platform set up

at the new offices The structured framework provided by

the joint project platform (JPP) has proved to

be an asset for managing all the issues that

require significant advance planning, mainly

in the line acceptance phase but also as

part of the preparations for operation and

maintenance. The JPP was set up under less

than ideal conditions given the Covid-19

crisis, but it did provide an opportunity to

establish the big picture of those issues

of shared interest, to break these down

functionally, to involve the relevant parties

from each organisation, and to determine

the appropriate frequency of workshops.

This work is constantly evolving: at the end

of the first year of full operation, the JJP

dashboard has been restructured to reflect

the new challenges and targets set for 2021.

The monitoring committee ensured that

the JPP’s tools were properly implemented

throughout 2020.

Guaranteeing the safety

and security of the Grand Paris

Express structures In 2020, the workshops run by the cyber

security working group provided a

collaborative environment in which

Société du Grand Paris, Île-de-France

Mobilités and RATP Infrastructures were

able to jointly develop information system

matrices (presenting a list of the Grand Paris

Express information systems with their

associated level of cyber security) and the

roles and responsibilities matrix (presenting

the duties of RATP Infrastructures and

transport operators in relation to maintaining

and using information systems). Work on

the systems approval process has also

started. It should be noted that the systems

approval process will include a “project”

approval before the transfer of technical

management and then an “operational”

approval after the transfer.

To improve coordination with its partners in preparation for future operation and maintenance,

Société du Grand Paris has made a joint project platform available to its partners Île-de-France

Mobilités and RATP Infrastructures. This tripartite project platform works on all the issues that

require significant joint advance planning. It includes the teams from Société du Grand Paris,

those from Île-de-France Mobilités as the transport organisation authority and appointer of the

future transport operators of the Grand Paris Express lines, and those from RATP Infrastructures

as the maintainer of the new metro’s infrastructure. Formally launched in November 2019,

the teams now have a dedicated workspace on Société du Grand Paris’s new site. They work

under the close supervision of a steering committee that meets every two weeks and includes

the operational managers.

A working group with these three actors has also been set up to look at the security of the Grand

Paris Express information systems. The main objective of the workshops led by this working

group is to share and define the governance of cyber security and to define the roles and

responsibilities of each entity in the operation and maintenance phase.
