• low degree of automation in the implementation stage of BPs,

• implementation delay of BPs
• cognitively inadequate complexity of BPs as there does not exist a lucid division between BPs and their implementation details,
• process blindness of managers which constitutes upon lack of process query tools,
• invisible, complex interdependencies of BPs which cannot be captured by automated procedures assessing effects of their modification or trying to optimize them.

Additional challenges come from the knowledge sharing and reuse domain. They involve the following matters:

• knowledge of BPs is represented in heterogeneous information sources,
• evolution of BPs in time,
• discrepancies both in within the organizations and between different ones,
• strict control of knowledge flow from within the organisation.
