Business Analysis is a set of methods and techniques used as a link among stakeholders to understand the structure, policies, and operations of an organisation and recommend solutions that allow the organisation to achieve its objectives (IIBA: International Institute Of Business Analysis).
Business Analysis is understanding how organisations work and defining the capabilities an organisation requires to deliver products and services to external stakeholders. It includes the definition of the objectives of the organisation, how these objectives are connected to specific other objectives which determine the lines of action that an organisation has to carry out to reach those goals and objectives and define how the different organisational units and stakeholders, inside and outside that organisation, interact. (Taken from article Business Analysis, Scholarium)
Business Analysis is about understanding a business and its processes, proposing alternative solutions and defining the scope of the selected solution considering all the resources of the organisation. This is due to the fact that business processes constitute the fundamental pillar of the operation of any private or public organisation, so that its unambiguous identification and categorisation, functional understanding of its basic structure, analysis and redesign, and effective management of its performance are of greater relevance increasing the competitiveness of your company.
Organisations have realised the need for the implementation of these type of methods and techniques, and have even created areas within the organisation for this function. They have given themselves a variety of names including, systems analysts, business partners, business representatives, ambassadors, process engineers, business analysts, business architects, among others. However, they often do not know how best to perform this function and lack the efficiency of a professional company.
