Plan Buy Run - advantages & disadvantages

The plan-build-run (PBR) IT model is a traditional approach to IT management that divides the IT function into three distinct phases:

• Plan: 
  This involves developing a strategic plan for IT, including identifying the organization's IT needs, setting goals, and developing a roadmap for achieving those goals.
• Build: 
  This involves designing, developing, and implementing new IT solutions to meet the organization's needs.
• Run: 
  This phase involves operating and maintaining the organisation's IT infrastructure and applications.

The PBR model has several advantages, including:

• It provides a clear and structured approach to IT management.
• It helps to ensure that IT is aligned with the organization's business goals.
• It can help to improve efficiency and reduce costs.

However, the PBR model also has some disadvantages, including:

• It can be inflexible and slow to adapt to change.
• It can be difficult to coordinate the three phases of the model.
• It can lead to siloed thinking within the IT organization.

The PBR model is therefore seen as a waterfall approach to IT management, as each phase is completed sequentially before the next phase begins.
