Projcet management of multi-area DD's

In practice, many DD’s require simultaneous actions from different professionals. Legal DD co-works with IP, patent and brand protection and environmental DD. Financial DD co-works with commercial DD, especially for the validity of the business plan as well as with Tax and Legal DD for the proper recognition of deferred taxation and provision for legal disputes.
What should be the proper strategy to organize a holistic approach keeping in mind that is not always easy the cherry picking of service from different professional especially when they provide a full range of services.
