In ITIL Version 5, the digital product and service lifecycle is supported by 8 integrated lifecycle management activities. Rather than acting as a rigid, linear pipeline, these activities form a flexible, non-linear framework where activities can be combined and used iteratively based on real-world needs and outcomes.
1. Discover
Purpose: Explore and prioritize needs, opportunities, and overall strategic alignment.
Discover focuses on understanding why a product or service is needed before jumping into creation. It evaluates opportunities against strategic goals and consumer needs to ensure resources are spent on what actually matters.
- Key Focus: Identifying opportunities, prioritizing needs, ensuring strategic fit.
- Core Question: What do we need, why do we need it, and is this opportunity worth pursuing?
Real-World Application (Adopting a Cat): You feel a gap in your home life and realize you want companionship. You research what kind of pet fits your apartment, your work schedule, and your lifestyle. You decide that adopting a cat makes strategic sense for your household.
2. Design
Purpose: Translate identified needs into prototypes, specifications, and actionable blueprints.
Design takes the validated opportunity from Discover and defines what the solution looks like, how it will function, and how users will experience it. It covers functionality, architecture, operational workflows, and user experience.
- Key Focus: Creating specifications, prototypes, process workflows, and architectural models.
- Core Question: What are we going to create, how should it work, and what will it take to make it practical?
Real-World Application: You map out how your home will accommodate a cat. You sketch room layouts, decide where the litter box and scratching post will live, determine feeding schedules, and budget for food and veterinary care.
3. Acquire (Phase 1 — Supplies)
Purpose: Secure and allocate necessary resources, products, services, capabilities, and supplier partnerships.
Acquire secures the external or internal components required to build and run the solution. Sourcing decisions balance cost, quality, risk, sustainability, and operational capability across software, hardware, expertise, or vendor contracts.
- Key Focus: Sourcing resources, establishing supplier agreements, allocating capabilities.
- Core Question: What resources, services, or expertise do we need, and how do we obtain them?
Real-World Application: Before bringing a pet home, you go to the pet store to obtain the physical components: a scratching post, a litter box, litter, water bowls, food dishes, food, and toys.
4. Build
Purpose: Develop, integrate, test, and validate solutions according to designs and specifications.
Build transforms designs, specifications, and acquired resources into a functional solution through development, integration, testing, and validation.
- Key Focus: Construction, component integration, configuration, testing, verification.
- Core Question: Can we actually create the solution, integrate its parts, and verify that it works?
Real-World Application: You unbox and assemble the multi-tiered scratching post, set up the litter box in the bathroom, fill it with litter, and arrange the feeding station in the kitchen. Everything is assembled, configured, and ready.
Loop Back: Acquire Again — Because the Lifecycle Is Not Linear
Because ITIL 5 lifecycle activities are non-linear, you now loop back to Acquire to obtain the core entity after the environment has been built and verified.
Real-World Application: Now that the home environment is built and verified, you visit the local rescue organization or shelter to execute the adoption agreement and acquire the cat itself.
5. Transition
Purpose: Introduce new or updated products into operational environments and ensure effective onboarding/offboarding of suppliers.
Transition coordinates the movement of a completed, tested solution into an operational environment. It helps ensure that new or updated products are introduced effectively and that the solution is ready for operational use.
- Key Focus: Operational introduction, release coordination, supplier onboarding/offboarding, operational readiness.
- Core Question: How do we safely and effectively introduce this new or changed solution into the operational environment?
Real-World Application: You bring the cat home in its carrier, place it in a quiet, dedicated room with its supplies, and give it time to acclimate safely to its new surroundings before opening up the rest of the house.
6. Operate
Purpose: Maintain and monitor digital products and supporting systems to ensure optimal performance and reliability.
Operate focuses on keeping digital products and their supporting systems functioning effectively in the operational environment. It involves maintaining those products and systems and monitoring their performance so that issues affecting reliability or normal operation can be identified and addressed.
- Key Focus: System monitoring, routine maintenance, operational performance, and reliability.
- Core Question: Are the digital products and supporting systems operating reliably and performing as expected?
Real-World Application: You monitor the cat’s environment and keep the equipment and routines that support it functioning properly. The litter box is maintained, food and water systems are kept operational, and you watch for signs that something isn’t working as expected.
7. Deliver
Purpose: Provide services to users, manage user onboarding and offboarding, maintain service quality standards, and gather consumer feedback.
Deliver focuses on the actual provision of the service to users. While Operate maintains and monitors the digital products and supporting systems behind the service, Deliver is concerned with providing the service, managing user interactions such as onboarding and offboarding, maintaining expected service quality, and gathering feedback from consumers.
- Key Focus: Service provision, user onboarding/offboarding, service quality, and consumer feedback.
- Core Question: Are users receiving the service and experiencing the expected level of service quality?
Real-World Application: You interact with the cat during daily routines, feeding, and play sessions. You receive the companionship and enjoyment that motivated the decision to adopt a cat in the first place, while paying attention to how well the living routine is working.
8. Support
Purpose: Identify and resolve incidents, fulfill disaster recovery procedures, assist with service restoration, and capture consumer feedback.
Support handles situations where things go wrong or when users need intervention. It focuses on identifying and resolving incidents, fulfilling disaster recovery procedures, assisting with service restoration, and capturing consumer feedback.
- Key Focus: Incident identification and resolution, disaster recovery execution, service restoration, feedback capture.
- Core Question: Something has gone wrong or needs attention—how do we restore normal operation and address the issue?
Real-World Application: The cat gets sick or swallows something it shouldn’t. You immediately respond by taking the cat to the vet, following the appropriate treatment, and working to restore the cat to normal health. The experience and feedback can also provide information that may be useful for future improvements.
