You can also rely on guidelines or resources prepared by governmental agencies or professional associations.
In addition, explain in what areas you rely on your own skills in preparing estimates and in what areas you rely on the capabilities of computer programs in preparing cost estimates. Cite and incorporate content from the textbook and the references noted above.
