This is why novices had time to see if they fitted into the particular expression of the rule in the particular monastery. This was really necessary for a true co-operation in the daily lives of the men, creating peace and an atmosphere where the work of the community would not be disturbed. By their very nature rules, first and foremost, are a personal matter between Christ and the believer. Their outworking should not be reliant on co-operation from others or be tailored to fit specific circumstances. They should not be restricting in any sense, but should free us into the service of our Master, and bring the promised joy.
Obedience is an outward sign of an agreement.
Co-operation, or working together does not however have the structured outward appearance of two oxen yoked. For an analogy nearer home I would use a doubles partnership in tennis. A successful pair is able to work to a strategy that is effective in all circumstances without need for continuous consultation . A finely tuned partnership works instinctively . I believe it is like that with our partnership with the Lord.
