• Think Big
• We took some time to dream a vision on Data Driven Assurance and define a portfolio of Showcases to show its value
• Act Small
• We delivered the showcases to discover the actual benefits based on data pipeline automation and analytics
• Scale Fast
• We build the capabilities to deploy successful pilots and drive the benefits throughout the pools

The basics van Process Mining
18
• Event
• Registratie van activiteit met de benodigde elementen
• Eventlog
• Verzameling van events
• Case
• Set van events behorende tot dezelfde case
• Trace
• Volgorde waarin activiteiten door één case zijn doorlopen
• Proces model
• Samenvoeging van alle traces uit een eventlog
