Example text

Thus, the change patterns were identified by analyzing relatively stable states before and after IS change projects. The research approach consists of the following activities: • • • • • • Analysis of IS and BP definitions to find the objects of change - elements which alter during the changes. Testing the relevance and completeness of the set of identified change elements. Analysis of IS theories and change management literature to identify change options of elements and to identify sets of mutually dependent elements.

Most common complementary change patterns No Element Internal Extrec Extsend 1 Data New or Improved Received Handed over 2 3 Knowledge IS users New No change Handed over New Received Moved 4 IS activities Extended Received 5 6 BP activities Control Improved Improved Suspended or Handed over Handed over Improved Received Improved 7 Territory No change Handed over Received 8 Resources Cheaper or Different Cheaper More expensive 9 Products Improved Improved Improved Pattern Internal usually occurs in situations where the aim is to obtain new data about the business process or improve its activities [1], [4].

According to transaction cost theory [32] organization grows until cost of transaction does not exceed cost of the similar transaction in the market. To meet the conditions of theory, organization should perform the following analyses: (1) define enterprise BP, (2) identify costs of BP, and (3) compare BP costs with similar BP in market. Based on these analyses organization provides the following changes in elements: (1) improves data quality and create new data if it is necessary, (2)improves IS activities to obtain new data, (3) improves BP activities to decrease the cost of activities, (4) improves data and information exchange between employees, improve control of BP and product.
