DCNS selected XWiki Enterprise for its ability to launch new wiki sites very quickly as well as its application creation capabilities. The solution was also integrated with DCNS' single sign-on and its Liferay-based portal. XWiki had to meet DCNS' stringent security criteria in order to be implemented.

Context and stakes
DCNS is a company that started its transformation towards Enterprise 2.0 in 2009, when the first
roadmap for its collaborative platform was initiated. In 2010, the first collaborative spaces were
introduced (image library and workspaces), and since their introduction they have achieved a broad
usage across the whole organization.
As collaboration needs were becoming more and more numerous, the integration of a wiki was first
considered in 2011. DCNS wanted to use a wiki to capitalize and share knowledge. This project was
initiated by the Quality Department of Ruelle.
A wikis farm (named WIKEO) was established by the IT Department and integrated into the
collaborative platform during 2011. The first wikis were called "editorial" and were implemented during
2011 and 2012 for Collaborative Platform Online Help, IT procedures...
At the end of 2011, XWiki SAS introduced the ability to create applications in WIKEO and implemented
wikis called "forms": IT applications referral, WORKEO Spaces requests, Risk management forms for
the shipyards etc. In this business case, we will focus on one of the "form" wikis: the risk situation
declaration form.
Sector: defense and energy
Need: declaration form
Solution: business application
Product: XWiki Enterprise
« We chose XWiki for its advantages in terms of integration into
the enterprise world and for its Open Source model. We found a
product that goes well beyond the simple wiki. Its programming
capabilities respond to the numerous needs for catalogs and
forms within our company. Coupled with the responsiveness of
the XWiki SAS, this product is now blooming at DCNS. »

In the case of this particular wiki the objectives were among others:
 improving the security level on the yards by removing potential dangers as soon as possible
 the identification, monitoring and treatment of a maximum of risky situations based on the
principle of the Bird Pyramid (see diagram below)
Initially, observations were made using Excel files, which lead to:
 continual exchanges of the file by email
 versioning problems with the file and issues updating it
 a lack of visibility on the status of the registrants
 a lack of responsiveness in preventing the people responsible for actions
Needs and constraints
The risk situations assessment form had to:
 transfer applications in WIKEO
 have a centralized version, open to anyone in DCNS
 have visibility on the progress of actions

 keep stakeholders informed using instant email alerts
However, it also had to take into account a number of constraints. The solution provided needed to
be as simple as possible and to:
 encourage participation
 address different types of audience (construction sites employees, IT department members and
other support functions)
The XWiki SAS solution
XWiki SAS carried out a form allowing:
 the registrants to report dangerous situations using a set of standard fields
 sending emails automatically to the prevention team
 the responsible for the action to learn what the status of a request is and what actions have
been undertaken
The screenshots below show the forms of observation at risk sites.

Instant resolution or the forwarding to the responsible for the action
First results observed
The implementation of such applications in Form mode is fast and inexpensive.
 this gives the IT department some reactivity concerning business demands (less usage of
unofficial software and Access databases).
 a huge scope: from application forms to actions management or datasheets, usages are
numerous.
Regarding the risk situations assessment form:
 4000 findings created
 90-95% of cases treated
6 serious accidents, 60 light accidents and nearly 200 hardware problems were avoided.
With respect to wiki forms types at DCNS, there are currently (February 2013):
 5 WIKEO form types deployed
 2 in development
 2 in conception
More generally, WIKEO is a success at the level of editorial wikis as well as form wikis.
Some statistics regarding the usage of WIKEO (February 2013):
 10 to 15 active wikis
 between 4000 and 5000 visits per month
 between 300 and 400 contributions per month
