SUCCESS STORY – agile projects with k-infinity

Construction site planning and -securityat one of the big European rail operations

An example for:Agile projects

Engagement of business experts in development of IT solutions

Elimination of shadow IT

Successful data integration

Context construction site planning

• 5.2 Mio person hours in

• 560 big projects

• 15.000 construction sites

• 13.400 urgent repairs and

• 51.000 maintenance tasks

Before introducing k-infinity Excel was the tool used the purposes of construction site planning

The planer distributes Excel files among the

stakeholders

All stakeholders confirm, comment on

and complete the plan. This way, more and more Excel files are

created until …

… it is no more clear, which one is the valid

version. The consequence: decisions based not on up-to-date information.

This can be fatal, e.g., if the workers on-site and

the security coordination have different plan data about the blocked track.


9

It has been a long-standing goal for SBB to put an end to the Excel chaos and to establish a single source of truth

With the help of the semantic graph database k-infinity this has been made possible …


10

… the task was very challenging

Construction sites and security measures come in many different variants and are full of interdependencies

The project was on a very tight schedule many of the conceptual questions had to be discussed on the fly and were based on preliminary project results

Demanding plausibility and consistency checks had to be implemented

… construction sites include work packages and shifts. Shifts contain

the actual tasks.

Machines, material and persons are assigned to shifts or individual

tasks.

The machines are assembled to form

maintenance trains. Groups of

persons are assigned to the

deployment of the machine on-site.

At early planning stages we cannot tell, who will be available to work on a particular site. For this purpose we

need to use placeholders.

In the end, this is what a simplified model for one

particular task from a construction site can look like.

Necessary security measures depend on the type and the sequence of

tasks, the infrastructure elements involved, the possible restrictions and

blockings of tracks.

ConclusionDifferent business units had to agree on terminology and business logicThe use of Excel as a planning tool had not encouraged any such agreementsConstruction site planning needed a complex model with complex business rules and room for a great variety of different construction sites

Requirements for the data baseEngagement of non-IT-users in an agile development of the data modelRich representation, combined with a great schema flexibility
