First, I think your report exceeds the 4-page limit set by this assignment (you have around 5.5+ pages).
Operations:
A bit of rewording would be good. For example, in your very first paragraph:
"Inputs, for example such as raw materials, are transformed by the firm’s core operations and then delivered to customers".
Also noticed some grammar mistakes, e.g.:
"Retailers distributes the goods in their stores"
There isn't much to be modified in terms of content. You've researched Bunnings well and linked your research to syllabus dot points. Just make sure you avoid those little grammar mistakes. I noticed another one for example:
"Operations strategies that Bunnings have achieved".
Marketing:
Your marketing section is well-structured and you have clearly elaborated on Bunnings's 3 pillars and the 4 P's of marketing.
Again, grammar seems to be the bigger issue here, not the content - e.g.:
"
Lowest prices exists"
In terms of length, you should try to be less descriptive and instead write in a way that allows you to get straight to the point. This will allow you to reduce length as well as word count. For example:
"At the present time Currently, Bunnings has a lack of lacks an online presence".
Finance:
Your finance section looks much more compact, while still maintaining its purpose.
My only suggestion here would be to try and link your research more to the syllabus as most of that section is purely providing the results of your research.
Good research and good use of graphs and tables.
Human resources:
Your HR section looks the best. You've included solid research and have linked it to relevant HR syllabus dot points, in addition to the use of graphs.
Make sure to reword and fix the grammatical errors - e.g.:
"performance management comes in is/becomes relevant"
Similarly to marketing, you should try to sound less descriptive and attempt to get straight to the point, allowing you to shorten the length of this section.
I hope this helps, all the best!
