Don ' t over-engineer solutions. Think about what you can do  now .

Like  focus on value , this principle is heavily focused on the prevention of waste. Waste correlates with complexity. Higher complexity means there are more opportunities for waste to creep into a system.

Focus on delivering the desired outcome, not building the most elegant and elaborate solution. Use the minimum number of steps to deliver that outcome, ensuring you are not  over-processing  (delivering quality above and beyond what is required).

The second step is to conduct an objective current-state assessment of existing services and service management practices. This should include consideration of the users’ perception of the value being received, along with a review of people’s competencies and skills, the processes and procedures involved, the capabilities of the available technological solutions and the prevailing organizational culture. The success of an improvement initiative depends on a clear and accurate understanding of the starting point and the required impact of the initiative.

For example, an organization can measure the current net promoter score (NPS) from a customer satisfaction survey, conduct a benchmark survey against its competitors or review findings of operational statistics or audit reports to understand its current state. If this step is skipped, the current state will not be understood and there will not be an objective baseline measurement against which improvement can be measured.

Meet the needs of its customers

Satisfy the requirements of its stakeholders

Service management  is a set of specialized organizational capabilities for enabling value for customers in the form of services. These capabilities include tangible things like capital, people, and equipment, and can also include intangible things like knowledge, management and skills. These capabilities can also include intangible things, like knowledge, management, and skills.
