The term 'path' refers to an activity or an unbroken sequence of activities in a project network. The critical path is the longest sequence of activities through a project network from start to finish, the sum of whose durations determines the overall project duration.

Earned Value Management Handbook, Published by the Association for Project Management in March 2013 suggests that: ‘…Each work package comprises a number of activities to be performed. Each activity can be assigned to only a single work package. Each activity is a stepping stone towards completion of its parent work package.’
NB The CIOB Planning Protocol 2021 (CIOB PP21), a technical information sheet published by the Chartered Institute of Building (CIOB) in February 2021, defines an activity as: ‘A definable and measurable unit of work. Each activity has a start date, an end date and a duration.’
The glossary of statistical terms, published by the Organisation for Economic Co-operation and Development (OECD), states: ‘An activity is a process, i.e. the combination of actions that result in a certain set of products.’
