System of accounting of storage and expenditure of propane-butane gas

I can’t evaluate the professionalism of the executive because the project is not completed. The expression was never shown and transmitted to the test. Previous discussions of the project with the executive allowed to make conclusions about the presence of knowledge in this field, but even in 150 days instead of 45 taken work was not completed. The executive constantly depicted the violent activity. According to his descriptions, he was constantly doing something, rewriting, processing, sending a photo of the product, but in the end he was unable to perform.
