Business management software in high‐tech firms: the case of the IT services sector

The aim of the paper is to analyse the acceptance of business management software by focusing on high‐tech firms dedicated to information technologies and belonging to the service sector (IT high‐tech firms).

The authors have applied an extended technology acceptance model (TAM) which includes variables related to technological compatibility and web procurement. It has been tested through structural equation modelling.

The results show that IT high‐tech firms must understand the interrelationships that exist between different information technologies (IT) and must, therefore, acquire technological know‐how. This technological knowledge permits firms to improve their perceptions of ease of use and usefulness, obtaining better results when computerising their management.

IT high‐tech firms must be aware that investment in a specific IT may affect the subsequent performance of other IT, due to the synergies derived from the application of complementary systems. Therefore, continuous investment in IT encourages the acquisition of technological knowledge that can be exploited in the computerisation of the main organisational functions and lead to greater overall efficiency.

Studies of IT high‐tech firms based on behavioural models, such as TAM, are in short supply. An understanding of how firms that produce IT as an output also use it as an input in their productive process, allows us to evaluate the importance of acquiring technological knowledge. Moreover, IT high‐tech firms have repercussions in almost all the sectors of the economy because they usually handle the implementation, maintenance and development of IT in other firms.
