SECTION 6 | END USER INVOLVEMENT

Failing to involve end-users in the design process can have several negative consequences, including:

Poor usability: End-users have a unique perspective on the way they perform their work and the tasks they need to complete. If they are not involved in the design process, the system may not be designed to meet their needs and may be difficult or inefficient to use.
Low adoption: If end-users are not involved in the design process, they may not feel a sense of ownership or investment in the system. This can lead to low adoption rates and reduced use of the system, which can impact its effectiveness and efficiency.
Resistance to change: If end-users are not involved in the design process, they may feel that their needs and concerns have been ignored. This can lead to resistance to change and a lack of buy-in from the end-users, which can make it more difficult to implement and support the new system.
Unmet requirements: End-users have a deep understanding of their work processes and requirements. If they are not involved in the design process, it can be difficult to ensure that their needs are being met. This can result in a system that does not meet their needs and is less effective and efficient than it could be.
Missed opportunities: End-users may have ideas and suggestions for how the system could be improved or enhanced. If they are not involved in the design process, these ideas and suggestions may be missed, and the system may not be as innovative or effective as it could be.

Failing to involve end-users in the design process can have serious consequences, including poor usability, low adoption, resistance to change, unmet requirements, and missed opportunities. It is important to engage end-users in the design process to ensure that their needs are taken into consideration and that the system meets their requirements and has the best chance of success.
