As per the PMBOK guide, you can simply look at the Inputs and outputs of each of these processes
For Example - In order to Direct and Manage Project work , Any changes that you incorporate should be Accepted by the Change Control Board , There should be a baseline Project Management Plan against which you will execute your project which will include all your other plans as subsidiary plans
So these are two of your inputs or entry criteria.
You also need a Schedule baseline and a Cost Baseline
This would mean that you have a detailed schedule and you have sufficient information on what you are doing, when you are doing and at what cost
The Direct and Manage Project work will produce deliverable , which will be all your different documents like Solution Architecture Design , Detailed Design , Testing Artifacts - Installation and Operational Qualifications, User Acceptance Testing Documentation . When those deliverable are signed and accepted by your customer , in other words
The scope has been validated , You have exited Direct and Manage Project work and entered into the Validate Scope Activity.
Any process that has a Prefix called as "PLAN" also produces an associated artifact which has a suffix of "PLAN" . Example - You need a Human Resource Management Plan as you exit the "Plan Human Resource Management" process.
I would strongly suggest Looking at the Inputs and outputs of all processes above and that will definitely give you your entry exit criteria.
In Summary , You need to have a plan for these knowledge areas in your project.
They can all be in Your Project Management Plan as headings.
Scope Management
Time Management
Cost Management
Quality Management
Human Resource Management
Communications Management
Risk Management
Procurement Management
Stakeholder Management
Once you have the plans in place, then you execute your plans using Cost Forecasts, Project Schedules, Deliverable
