Shock is a life-threatening condition that occurs when the body is not getting enough blood flow. The main types of shock include: cardiogenic shock, hypovolemic shock, neurogenic shock, and septic shock. Differentiation is very necessary as the management to all these form of shock vary. While hypovolemic shock requires aggressive fluid resuscitation to treat hypotension and a thorough evaluation to exclude any ongoing blood loss, the choice of therapy in neurogenic shock is vasopressors, such as dopamine, to overcome low blood pressure. Although it’s true that all types of shock can lead to the same final stage of multi-organ failure as a result of the imbalance between oxygen demand and supply, the differences in their pathogenesis and pathophysiology make it desirable to change their classification because different therapeutic measures are needed for the different types of shock.
The primary artefact in Scrum is the Product Backlog. This backlog is a collection of requirements, often stated in user stories. The backlog is the project’s only source to the requirements. During Sprint planning the development team pulls backlog items into the sprint backlog. Normally a sprint duration is between two to four weeks (all the collaborating companies have sprint of three weeks duration). The primary ceremony in Scrum is the daily Scrum (daily stand-up), where the team have 15 minutes to talk about progress and obstacles in the work. At the end of the sprint, the whole team first performs a sprint review, often together with all stakeholders, the goal is to have a potentially shippable product increment that has been tested and is functional. To finalize the sprint, the team has a sprint retrospective to inspect itself and compose a plan for improvements, which can be executed during the next sprint.
1.3. USABILITY AND UX
When working with usability and UX it is important to have a shared understanding and foundation to the notion of especially UX. Different approaches exist when it comes to distinguish between usability and UX. However, all approaches agree upon UX originating from usability, and the change from usability towards UX includes a more positive, holistic, non-instrumental and hedonic view. [REF]
1.3.1. USABILITY
Usability is by the ISO 9241 standard defined as: “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.” [REF]
Usability engineering focuses on the ease of use and learnability, efficiency, memorability, errors and satisfaction of a product and on how the interaction can be measured. (Nielsen, 1994) Usability often focuses on executing tests with the focus on removing inferior and non-usable elements from a product, thus it is very risk oriented. [REF] Focus is on the efficiency of using the product rather than understanding how people experience the product. Hence usability methods have a more quantitative nature and include AB-testing, performance tests, usability evaluations, etc. [REF]
