Methodology

In ARCH.144 the enterprise and its goals are defined.

In ARCH.009 a set of metrics/measures is defined to quantify the railway infrastructure's operational effectiveness (that is, the degree to which the goals are achieved).

In this activity, target values are to be defined for these measures of effectiveness.

It will probably not be possible to arrive at a single target value for every possible application of System of interest. Measures of effectiveness can be imagined at national level but also at local levels and they may vary.

For example, while overall railway capacity may increase by 35% nationally, it does not follow that every railway that deploys System of interest needs to achieve a 35% capacity increase. Some will achieve higher, and some lower.

The intention is to establish targets that will drive the performance targets of System of interest to a level where System of interest is sufficient to be used widely on e.g. DB. In this activity, a strategic decision needs to be made whether that means setting the MoE targets to reflect the most demanding digital railway operations, or to a less strict value, whereby we would accept that System of interest would not be the right solution for some worst-case scenarios.

These strategic decisions should be driven by e.g. senior DB management but it is for our team to organise the activity and obtain answers to all open points so that the development of System of interest can be guided by a vision of the level of effectiveness the digital railway is expected to achieve.

General approach should be:

  • identify the stakeholders who can give an authoritative decision on what the measures of effectiveness should be (for any MoEs where the target is not already fixed by strategies such as Starke Schiene)
  • consult the stakeholders to seek their opinions on the correct targets
  • obtain consensus agreement/compromises such that all stakeholders are satisfied
  • document the MoE targets in the CONOPS
