A deliverable is a tangible output: a document, a build, a completed feature. Milestones are typically on the schedule as zero-duration events. Deliverables are the things that get handed off and reviewed. A project review meeting is a milestone. The report presented at that meeting is a deliverable."},{"question":"What PM terms appear most often in contracts?","answer":"The terms most likely to appear in client contracts are: statement of work, deliverable, acceptance criteria, change order, milestone payment, scope of work, and force majeure. Understanding these precisely matters more than most PM vocabulary because misinterpretation creates legal and financial exposure. When reviewing a contract, the definition of \"acceptance\" is often the most important term to clarify upfront."},{"question":"Are Agile terms standardized across organizations?","answer":"No. Agile terms vary significantly by organization and even by team. Some teams use \"sprint\" and \"iteration\" interchangeably. Others treat them as distinct concepts. \"Backlog grooming\" is now officially called \"backlog refinement\" in the Scrum Guide, but both terms are in active use. When joining a new team or organization, it is worth confirming the local definition of any Agile term before assuming it matches the textbook definition."},{"question":"What does earned value mean in project management?","answer":"Earned value is the budgeted cost of the work that has actually been completed at a given point in time. It lets you measure schedule and cost performance on a single scale. If you planned to complete $100,000 worth of work by today but have only completed $75,000 worth, you have a schedule variance of negative $25,000. Earned value analysis is most useful on large projects with formal budget tracking. It adds overhead that smaller projects rarely justify."}],"faq_heading":"","product_cta_primary":{"label":"Try ClickUp Free","description":"","url":""},"product_cta_secondary":{"label":"","description":"","url":""},"breadcrumb_label":"Project Management Terms","hide_breadcrumb_switcher":false,"author_name":"","author_title":"","related_topics":[70391,70394],"hub_key_takeaway":"Every PM term in this section has a practical consequence.
