Part wise / Section wise word count compliance is mandatory ?

In a few words: provided you have covered what is necessary for Part 2, i.e. mentioned the main sources, introduced the models and adequately considered all limitations then how you use the word count is up to you. (Mostly all that is required in Part 1 are the research objectives and questions) I always recommend at least 4,500 words for Part 3 to ensure adequate analysis.

Word count is just a guidance for PARTS, I had very low word count in part 1 and 2, but did cover the necessary requirements. Used most of the count in Part 3 - which is crucial. But overall, the word count MUST be in compliance, 7,500, its distribution is up to you. Regards,

One word of caution - I have seen feedback warning about using too many models almost for the sake of it and markers telling students to have fewer models but applying them well rather than too many and applying them thinly. I think some form of change management needs to be discussed here for T7 and I think with some of the models you have set out there is some duplication. So be brutal with yourself and ask yourself why you are including a particular model and if it is adding value to your analysis and contributing to the achievement of your objectives? Unless it is then remove it to allow better use of the word count. Ps I have been told that in Part 1 there should be some justification of topic choice and company as well as research objectives but you should still keep this section as short as you can

Exactly, 2 models well explained are ENOUGH! 4 business models will stretch you too thin and is 100% for fail.
