What is essential for enabling target users to access multiple systems?

Supporting business processes across the organization is essential for enabling target users to access multiple systems because it ensures that all relevant workflows and systems interact seamlessly. When business processes are well-defined and integrated, users can access the necessary data and functions from different systems without navigating through each system independently. This integration facilitates a holistic approach to operations, allowing users to perform their tasks more efficiently and effectively by leveraging multiple systems at once.

In contrast, integrating legacy systems alone may not encompass the broader range of systems that users need to access. Breaking large projects into smaller tasks focuses on project management and execution but does not directly address user access to systems. Creating simple user interfaces enhances usability but does not guarantee the necessary integration between systems that support comprehensive business processes. Therefore, supporting cross-organizational processes is fundamental to achieving the goal of accessibility to multiple systems for users.
