| - | The wearable elderly monitoring device provides autonomous elderly persons, the family of a semi-autonomous elderly person or a full-time caretaker of an elderly person with information to avoid or detect as soon as possible a potentially fatal situation. Researches show that in the next 10 years the average life expectancy at the age of 10 in developed countries rises from 74.5 to 76.5 ((roser)). With the growth of life expectancy, there are going to be more and more elderly persons to take care of. This means families and the government need to invest a lot more into elderly care and make innovations in monitoring one of the weakest social groups. For this reason, it is essential to research and create an overview of the main causes of elderly persons losing autonomy in the form of a State of the Art analysis. | + | The wearable elderly monitoring device provides autonomous elderly persons, the family of a semi-autonomous elderly person, or a full-time caretaker of an elderly person with information to avoid or detect as soon as possible a potentially fatal situation.

Starting with sleep monitoring and heart rate tracking and ending with the fitness tracker that measures your every move. This product has one interesting aspect that differs from other fitness trackers, Blood Oxygen Saturation tracking. Garmin says that the sensor gauges your blood oxygen saturation levels at night to help you better understand your sleep quality. The new advanced sleep monitor estimates light, deep and REM stages of sleep, along with movement throughout the night.

| For the good management of this project, the agile SCRUM methodology was used. To create the overall image of the project is created Product Backlog which contains all includes the essential tasks. These are selected in order of priority and are included in the weekly sprints. Also, depending on the work capacity of the team, a certain number of tasks are chosen. At the end of each sprint, velocity is calculated and sprint review and retrospective are established. In this way, the time is very well organized to be able to meet all deadlines and each member knows exactly what to do. Therefore, sprint outcomes and evaluations are made to take steps to streamline planning. | For the good management of this project, the agile SCRUM methodology was used.

| The WBS is a method for getting a complex, multi-step project done. It's a way to divide and conquer large projects so you can get things done faster and more efficiently. Work breakdown structure (or WBS) is a hierarchical tree structure that outlines your project and breaks it down into smaller, more manageable portions. You can build a WBS by creating folders and subfolders, and can even go further to divide individual tasks into subtasks. The goal of this structure is to make a large project more manageable. Breaking it down into smaller chunks means work can be done simultaneously by different team members, leading to better team productivity and easier project management overall ((wrikewbs)). | The WBS is a method for getting a complex, multi-step project done.
