Organisation: "The Organisation element of the POPIT model is concerned with the structure, job roles, culture, management style and politics of the business system." (Chapter 4, Section 4.5.2, p. 69). This directly supports the analysis of issue 1.
Information and Technology: "Information relates to the data that is held and used by the organisation... Technology is the software and hardware used by the organisation to support the business processes." (Chapter 4, Section 4.5.2, p. 70). This covers the data sharing and associated legal aspects of issue 2.

The syllabus explicitly lists the four elements of the POPIT model as Processes, People, Organisation, and Information & Technology. It states that candidates should be able to "Describe the four elements of the POPIT model" and "Explain how the POPIT model can be used to identify issues to be addressed within a business change." (Section 3.2, p. 10). This confirms the correct elements and the exclusion of 'Procedures'.
