Revision 1 Summary: This report was a good overview not only of Caterpillar but of organizational IT infrastructure in general To improve, discuss specific strategies and tactics that Caterpillar uses to address its IT operating technology or provide customer support. This will give more substance to your report.
Revision 2 You conceptualized each problem well and included multiple references to support the solutions and key points identified. Appropriate rationale is used and detailed information helps convince the reader about the conclusions. Work to be sure that even more specific conclusions are arrived at and tied to the analysis you conducted. Sometimes the wording is vague and needs more specific context.
Revision 3 Writing is very good. One or two small issues exist and can be easily corrected in a final proofread: One of your subtopics: "Information Technological Farriers" needs to be edited. I'm not quite sure about the meaning of the final sentence in your paper. Can you clarify this in your final version? "Certain types of agreements are usually thorough and provide a clear assessment of the requisite improvement efforts involved in either an intelligent approach or a comprehensive approach."
