The specifications are where you’ll find every detail about your project. This, the most comprehensive of our services, guarantees a feasible and optimal lead time for your mobility project. With thorough, detailed specifications, Treelight ensures that your HASTUS® application meets your expectations – without any bumps along the way.

While you work with GIRO to draw up the specifications, Treelight guides you to define them as accurately and correctly as possible. Based on its in-depth knowledge and expertise in the mobility industry, the Treelight team makes sure that all decisions are benificial to the overall solution.


Treelight helps you through certain configuration processes by writing attributes and validations or OIG/OIR interfaces.


Treelight assists you when writing change requests that are carried out by GIRO.


Treelight examines how we can best align your business processes with the software. This can be done in two ways:


  • By using the Adopt principle, we apply the generic behaviour of the application to your business processes.
  • By tailoring the software to your needs in consultation with the supplier GIRO.

Dave is a ‘challenger’: as an expert, as an advisor, as a team player. As an expert in workforce planning, he challenged his own creativity resulting in the creation of a total new way of operator planning (PWR). As an expert in Hastus Software he challenges you to choose the most optimized solution. As an advisor he challenges the way you look at your processes and work procedures. As a team player he realizes, together with you the best solution for your scheduling and workforce planning. Grateful to have got Dave in my team and realize our challenges at De Lijn.
