When business competition is increased, it is possible that legacy software could not serve the response on business requirements. Software purchasing is the solution that could help organizations to take action on dynamically requirements. Some organizations have been successfully implemented new software while some fail according to the differences of risk management processes that selected from each organization. Therefore, a survey of risk management processes in various business organizations in Thailand had been performed and proposed the most accurately risk management procedure which are proof of concept and product prototype analysis that could reduce percentage of failure comparing with organizations’ satisfaction rate. Additionally, the experimental results have shown that applying standard risk management process do not meet user satisfaction while proposed risk management process of Thai’s organizations performed better results rather than standard.
