"Conservation treatment services can be procured by purchase order or by contracting for those services. Success begins by matching the appropriate procurement method with project needs. Good performance starts with a well-written scope of work, and a contract that can be exercised must contain a clear statement of specific deliverables and a delivery schedule. Competed contracts need specific performance and ability relevant selection criteria as well. If you are not sure about what type of procurement method is right for you, contact your procurement specialist or officer for advice."
