Progress on TO BE

1. Added a new introduction section that addresses point 1 (conceptual modelling in general)
     PA:  Is it bitty? too long?
             Reviewer asks that the case is made for the need for SCM academics.

Add refs

2. Conmtribution - seems more clearer now. 

    PA: to tidy up?

3.  Pavel to check whether the references to Weaver (2010) are necessary?

4. Similar to 3, not many perspectives exist. Argue this case.

5.  Tables are reformed.

6.  This requires a good read / revise.

7.  Paper is made more unique.

8.  Made clear that is a case illustration.

Miles to check:   it says case illustrations.


Utility section:
- take out 5.1 -- check?
- take out bits now in methodology section -- check?
- describe the problems

General comment:

tables explained in text

Outstanding for Miles:
References need to be done
