Most schools do not realize full advantages of scaling up due to administrative challenges and manual processing of student data. MIS systems allow for great automation of most processes freeing up time for teachers to concentrate on core functions.

9. THE ROLE OF INFORMATION
SYSTEMS
Oshwal Academy N&M will invest heavily in information
systems to achieve four strategic business objectives:
1.Operational excellence; reduce cost and add value to the
operation
2. Customer and supplier intimacy - Collect customers
history so as analyze customers information and offer
appropriate services
3. Improved decision making - Good decisions lead to
better response times and improved outcomes of
processes
4. Competitive advantage; create innovation or do something
different from competitors such as seamless operation etc.

This is based on Lyytinen’s sociotechnical model of risk
Actors relate to all those involved in the project including both developers, users and managers e.g. a risk could be that high staff turnover leads to information of importance to the project being lost
Technology – both that used to implement the project and that embedded in the project deliverables – risk could be that the technologies selected are not in fact appropriate.
Structure – this includes management procedures, risk here is that a group who need to carry out a particular project task are not informed of this need because they are not part of the project communication network
Tasks – the work to be carried out. A typical risk is that the amount of effort needed to carry out the task is underestimated.
A risk could be well belong to more than one of the four areas – for example, estimates being wrong could be influenced by problems with actors (e.g. lack of experience with a technical domain) or the structure (over optimism of managers keen to win work).
Exercise 7.2 in the text will be some practice in identifying and categorizing risks
Barry Boehm surveyed software engineering project leaders to find out the main risks that they had experienced with their projects. For each risk, some risk reduction techniques has been suggested.
