"The schedule contains all the activities that need to be performed, including their sequence and interdependencies, milestones, duration, estimated effort, start and end dates, as well as resource assignment. In addition, it should detail the critical path or paths." (Lars Dittmann et al, "Automotive SPICE in Practice", 2008)
"An ordered set of tasks characterized by duration and loading onto resources. For project management, this is the plan that specifies which people should perform what tasks when. For a concurrent system, this is a statement of what tasks should be executed by the scheduler and when." (Bruce P Douglass, "Real-Time Agility", 2009)

"Time plan for a project or process. Note: on a construction project this is usually referred to as a 'project programme'. The construction industry tends to refer to programmes rather than schedules. Indeed the term schedule tends to mean a schedule of items in tabular form, e.g. door schedule, ironmongery schedule, etc." (Chartered Institute of Building, "Code of Practice for Project Management for Construction and Development" 5th Ed., 2014)
