Inside the application
Relationships and project potential
The network overview groups contacts by relationship closeness and project potential. Reminders of pending conversations and next steps support ongoing relationship management.
From project opportunity to contract
Sales brings together reviewing project opportunities, shortlisting, acquisition, proposals and contracts. The pipeline shows the current state and highlights where decisions are needed next.
Maintain a structured competency catalogue
The knowledge area organises skills, methods, concepts and technologies in a searchable catalogue. Experience, relevance and website selection support personal maintenance and approved public presentation.
