Life is full of making key decisions. Business’ use information systems to enhance and improve their decision making processes’. This is one of the main contributions of IS to business’. These decisions are undertaken at different levels of the business. These business levels are the operational level, managerial level and the executive/strategic level. The aim of this is to help business’ in both structured and unstructured environments, supporting decision making at all levels of the organisation.
This is a diagram that will help describe the different levels within an organisation:
There are 4 stages for decision making which include intelligence (Discovering the problem that an organisation faces), design(What are the possible solutions to solve this problem), choice (Choosing which option would best solve the problem) and finally, Implementation (This is to see if the implemented solution is working and whether it can be improved).
There are also three types of decisions that organisations face. These are structured decisions (repetitive), unstructured decisions (requires judgement and insight to solve) and semi-structured decisions (only part of the problem has clear-cut answer). However, for a decision to exist, there must be decision makers, goals to be served, relevant alternatives, ordering alternatives and a choice of alternatives.
To conclude, today mangers use information systems to help them with decisions surrounding them. Mangers have access to a handful of data, but can’t organize this information manually as it would be far too time consuming in this modern, competitive world. Therefore, managers depend on information systems.
