bottom-up
Synonym discussion
Sense: adjective/1
Bottom-up stresses the direction of development: you begin with small units, local facts, or team-level needs, and only later form the larger result. Grassroots is close when ordinary people, not senior leaders, push the action forward. Participatory focuses on people taking part in decisions, even if the system is not strictly built upward from details. Community-led is narrower still, and is most natural when a local community clearly guides the work. So a company can use a bottom-up budget, a town can face grassroots pressure, and a school can hold a participatory meeting. Say a bottom-up hiring plan when ideas start with each team rather than the board.

Etymology
This compound joins bottom and up. It comes from the image of movement starting at the lower levels and rising higher, so it is used for plans or systems built from small parts, local groups, or junior levels first.
