The implementation of technologies is a real opportunity to re-engineer the whole processIf the technology is implemented without adaptingthe rest of the process, there is a high risk to create important problems (workaround, new risks, inefficiency,…)The use of process analysis tools isrecommended :

Automation and robotisation are important strategies to optimize drug management
Safety, traceability and efficiency can be improved
The implementation must be intelligently and interdisciplinary decided and planified
These projects are very challenging and must be leadedby a competent and available team
A strategic vision should be elaborated by any hospital
