Increased efficiency through the introduction of a Field Service Management system
In order to make the deployment planning and order processing of the fitters more efficient and up-to-date and to avoid media breaks, DREWAG decided to introduce a Field Service Management System in 2011. In a tendering process, various providers and solutions were evaluated. A key criterion was the ability to integrate with the backend systems SAP PM and various resource information systems based on Oracle. Finally, the choice was made in favor of mobileX-Dispatch, the field service management system for the scheduling of mobile resources, and mobileX-MIP for Field Service, the mobile solution for the order processing of technicians on site. In 2013, the two solutions for the gas, water, district heating and electricity sectors were introduced at DREWAG in a first expansion stage. Subsequently, the gradual implementation for the individual business processes took place over several expansion stages.
The schedulers plan the service and maintenance orders for the fitters about two weeks in advance. In doing so, they use a wizard in mobileX-Dispatch as a template generator for creating the operations of SAP PM collective orders. The templates are structured according to divisions, task groups and activities. The dispatchers select default values for the activities from a list. This shortens the input process and ensures the correct assignment to the collective orders.
The fitters now receive their orders directly on their mobile devices. This gives them offline access to all relevant information such as the plant structure, object data, usage history and notifications in SAP PM and the backend system SIS. It is also possible to jump to an offline GIS to view the network history there and, for example, to search for the origin of faults in a particular area.
In mobileX-MIP for Field Service, the technician on site records the system status. In doing so, data such as measurement documents are checked for plausibility directly upon entry. The check criteria for this are transferred from SAP PM to the mobile device and used during entry. The confirmations for the orders and daily reports are transmitted directly to the backend systems by mobileX-MIP for Field Service. This eliminates the time-consuming, manual transfer of data from paper documents.
Savings potential through digitalization of paper forms
Another major productivity advance was made in 2016 with the introduction of Dynamic Forms – an add-on module of mobileX-MIP for Field Service for digitizing paper forms. For the so-called mass processes such as the inspection of gas or water fittings, hydrants or substations, fitters previously had to fill out different paper forms. A total of about 38,000 documents were created per year. Filling out these forms and manually transferring the data to the back-end systems alone took a total of 424 working days. With the help of the dynamic forms of mobileX-MIP, these paper forms were digitized centrally and rolled out to the fitters. They can now fill them out directly on their mobile devices. In the form itself, they can maintain the characteristics via selection catalogs, integrate photos, perform redlining and sign. Once they have completed the order, the data is transferred to the back-end system both structured as a data record and unstructured as a PDF document.
