Cost Estimation for Object Controlling Software Development
Customer: SBB, Switzerland
Project tasks
- Analysis of the modular concept
- Verification of the basis technology
- Estimation of the development time
- Estimation of the development efforts
- Evaluation of risks
Our Approach
As part of the industry program SmartRail 4.0, SBB are developing a concept for a geometric ETCS interlocking system. The Object Controller is the connecting element between the existing interlocking system, the new generation of interlocking systems and the existing trackside assets. To be able to estimate the basis technology and the development time as well as the development effort, PROSE was commissioned to evaluate the existing concept documents and to create the evaluation documents.
PROSE put together a team of experienced vehicle maintenance experts. The work contents and processes were systematically analysed and proposals for adjustments and possible improvements were formulated. In a second phase, the identified areas were discussed in workshops with specialists from RAlpin and the maintenance service provider and the final formulation of the work contents and processes for the regulations were determined. The documents were revised by PROSE and a new revision was prepared for release.
Customer benefit
SBB already has experienced employees in the field of safety-related systems. But since the Object Controller was very important for the migration, and to assure a higher precision in the estimation of development effort and time, as well as to identify further possible risks, PROSE was contacted for a second opinion. PROSE has employees experienced in signalling and software development as well as safety-related issues. These experiences are combined in a wellversed team to the benefit of the customer.
