Bird's-eye view
We split all work in Clarity in small chunks of work called Tasks. All tasks belong to a Backlog - a logical collection of work for a single Team. Team comprises Team leader - person responsible for management of the Backlog and Team members - people implementing tasks.
Each task has optional business Priority ensuring implementation order - there are two predefined ways to prioritize tasks in Clarity - using a high level prioritization technique called Rank and a low level prioritization model called CaPRICE. All tasks are also explicitly prioritized using Stages.
Each task has a Status and Stage. Status shows the current life-cycle stage of a task - is it in progress, is it waiting to be worked on and similar. Stage shows the current planning, preparedness status and absolute priority of a task - should it be worked on now, is it ready to be worked on and similar.
We organize all work in progress using iterative Delivery cycles. Delivery cycle is a brief period of time Team works to complete a set of tasks. Delivery cycles help split projects in manageable iterations of work. There are always two pre-defined Delivery cycles that are defined using special task Stages - Now and Next.
We can organize tasks using Goals - goals are specific to single Backlog and Team and group tasks under same logical business goal.
We can organize Goals using Objectives. An Objective is a high level business milestone that groups many Goals. We can share Objectives between multiple Teams and Backlogs.
We can organize multiple related Objectives together using Visions. A Vision is a group of Objectives to fulfill a general business vision and direction. Visions are organization-wide.
Using Goals, Objectives and Visions is optional but recommended.
Clarity facilitates continuous improvement at all levels of the organization. We do this using Retrospectives and Reviews.
