BiSL (Business Information Services Library) and ITIL (IT Infrastructure Library) are complementary frameworks that address different layers of the IT organization.
What They Cover
ITIL focuses on IT service management (ITSM) — the delivery and support of IT services. BiSL focuses on business information management (BIM) — aligning IT usage with business needs, especially from the user organization’s perspective.
Key Differences
- Perspective: ITIL views services from the IT provider side; BiSL focuses on the demand side (business).
- Processes: ITIL includes incident, change, and problem management; BiSL includes functional management, information policy, and user demand processes.
- Goal: ITIL aims at stable service delivery; BiSL aims at effective use of information within business processes.
Why Combine?
Organizations that combine BiSL and ITIL bridge the gap between IT delivery and business expectations — ensuring both supply and demand are managed professionally.
