21. st century business environment forces organization to move faster, be more efficient and change more frequently than ever before, if they want to keep their position or to gather new markets and new clients. Business agility is the key for success and becomes one of the priorities in strategic goals of every organization.
Information systems in organizations should support business processes and strategic goals. This is possible only by complete integration of business processes and information systems, making information technologies one of the key elements for achieving organizational goals, on every business level.
Most of the organization today has some kind of Information systems, however, it is very questionable how much are these systems aligned with the business processes and business strategy. In most of the cases, IS implementation is based on \'snapshot\' of business processes in some moment in time, but after a while, when there are some changes in business processes, it becomes very difficult or very expensive to preserve this alignment and the final result is information system which does not fully support new and changed business processes inside the organization.
The best solution for this problem is using Service Oriented Architecture ( SOA ) for design and implementation of information systems. Main concepts of SOA are \'Business functions – services\' which are direct connection between business and IT. SOA is for the moment most efficient and most effective solution for building effective and sustainable information systems completely integrated and aligned with business processes inside the organization.
To use SOA for design and implementation of IS, it is needed to change the way of modelling business processes as well. Only integration of SOA and BPM would give desired results, which will support strategy and increase agility of organization.
This paper defines basic concepts of Service Oriented Architecture and Business Process Management, using case study of modelling business processes in microcredit organization. IT shows the simple way to start implementation of SOA concept, at the same time stressing importance of integrate approach which includes Business processes redesign.
By introducing concept of \'Services\' which are defined as \'Business services\' from a business point of view, and as \'Web Services\' or basic components of information systems, creates a best environment for mutual understanding between \'business\' and \'technology\' parts of the organization, making possible for different views on processes co-exists and create integrated, effective and productive platform for supporting organization on every business level.
IT is not necessary for SOA projects to be large, neither to demand huge resources or dramatic changes in organization. Any project which is implemented according to SOA standards could be a Pilot project for SOA implementation in organization. Properly implemented SOA principles, with appropriate metrics for validation of results and alignment with organizational strategy, SOA will have to be unavoidable approach for redesign of the information systems and business processes as well.
This paper will present SOA concepts in simple and understandable way, including design, implementation and validation of the complete SOA project.
