Workflow Patterns and BPMN

Business processes can be automated using Workflow Management Systems. The choice of a Workflow Management System is an important step for every organisation because the amount of modeling and implementation effort invested over time is significant. The choice of such a system is based on functional and non-functional requirements. The workflow patterns can be seen as a systematic guide for the functional requirements. The workflow patterns explain the modeling features a Workflow Management System may and can be used to compare different options.

We started with the 43 workflow patterns on control flow and have analysed how they can be modeled in BPMN and how they can be implemented in Camunda. The results are published in the form of a series of Youtube videos that has started in 2023 and will be finished in 2024:

The servers in Rheni’s computing centre are solar-powered since August 2022. 48 solar panels are producing ample energy to operate the servers and fill a rechargeable lithium-ion battery¬†during sunlight hours. The battery takes over as soon as the sun goes down. Also in the domain of mobility, Rheni is moving from Diesel-powered four-wheelers to electric-powered two-wheelers. All these¬†“green” ideas have worked well from August til October. Unfortunately, during the month of November in our latitude, the days become too short, the sunlight too weak, and the temperatures too low. This means back to Diesel power and electric current from the grid and pray for the sun to come back in March…
