## 3 Overview of Information Systems
### Stages of Implementing an Information System
The process of identifying and defining KPIs should be systematic and inclusive. The following methods can be employed to ensure effective stakeholder engagement:  
* Workshops and focus groups with interactive sessions with stakeholders to brainstorm and discuss potential KPIs. This method fosters a collaborative environment where ideas can be shared and refined collectively. * Surveys and questionnaires to gather quantitative and qualitative data on what stakeholders consider important metrics for evaluating digital health interventions. Interviews with key stakeholders to gain in-depth insights into their specific needs, challenges, and expectations. In conclusion, the engagement of various stakeholders in the development of KPIs for digital health interventions is a fundamental step towards ensuring their effectiveness and acceptance. By employing structured methods for identifying and defining KPIs, we can create robust, relevant, and impactful metrics that drive the successful assessment and adoption of digital health solutions [31]. KPIs for assessing and adopting digital health interventions can vary depending on the specific intervention and its goals. However, some common KPIs are presented in Figure 2:8  
To ensure project success and process optimization, the team must possess extensive expertise. Any delays and miscommunication, along with a shortage of expertise, vague objectives, and the neglect of best practices, could potentially harm the entire institution and its personnel. During the implementation of an information system, end-users encounter challenges, including reluctance toward new systems, which necessitates attention from both the team and management. Factors to take into consideration include the following:  
* The fear of change--Humans are creatures of habit, and change can be unsettling. Introducing a new system means disrupting familiar workflows and routines, which can evoke fear and resistance among users who prefer the status quo. * The lack of familiarity with the new system entails learning to use a new system, which requires time and effort. Users may feel overwhelmed or intimidated by unfamiliar \begin{table}
