Lecture Business system development - Lecture 24: Installation & operations. In this lecture we talked about : Cultural Issues and information technology, conversion, change management, post-implementation activities. | Business System Development CSC581 Lecture 24 Installation & Operations 2 Summary of the previous lecture In previous lecture, we : Discussed the Maintenance Phase and the activities carried out there. We also talked about the mini-SDLC We discussed changed management and other issues related to the Maintenance Phase. Outlines We today’s lecture we will: Understand different types of conversion strategies and when to use them. Understand several techniques for managing change. Be familiar with post-installation processes. Introduction Managing the change to a new system is one of the most difficult tasks in any organization Conversion planning normally begins while the programmers are still coding Change management focuses on people Maintenance can account for 60-80% of IS budget A Model for Implementing Change As-Is System To-Be System Transition Unfreeze Analysis & Design Move Migration plan: Technical Conversion Change Management Refreeze Support & Maintenance Cultural Issues . | Business System Development CSC581 Lecture 24 Installation & Operations 2 Summary of the previous lecture In previous lecture, we : Discussed the Maintenance Phase and the activities carried out there.
