I think one of the resources that may be helpful to this question is to read

Thank you

The popular laws of project management include the following:

• No major project is ever installed on time, within budget, or with the same staff that started it. Yours will not be the first.
• Projects progress quickly until they become 90% complete, then they remain at 90% complete forever.
• When things are going well, something will go wrong.
• When things just cannot get any worse, they will.
• When things appear to be going better, you have overlooked something.
• No system is ever completely debugged. Attempts to debug a system inevitably introduce new bugs that are even harder to find.
• A carelessly planned project will take three times longer to complete than expected
• A carefully planned project will take only twice as long.
• Project teams detest progress reporting because it vividly manifests their lack of progress.
