Technicians and workers got their documents, job data, instructions, plans etc. from different media. In situations where additional service was needed, a call was executed or a service ticket was created. This caused inconsistency in the up-to-datedness of information. By providing all information on jobs, instructions or plans via mobile services, technicians get all information via one system. Digital checklists guide the technician through a job, allowing documentation immediately and in the same system. Real-time updates are not only guaranteed for the technician but also for back offices or customers. Clients can also give orders directly via the system. The same method is used for controlling and acceptance procedures and approvals for charging. Augmented reality elements can be integrated to extend the functionality of the solution.
