Piece coordination
Piece coordination is the degree to which your pieces support one another and work toward the same target, so their combined force is greater than the sum of what each could do alone.
Also called: coordination
Good coordination means your pieces work as a team. Two pieces aimed at the same weakness, a rook backing a knight that has landed on an outpost, or a queen and bishop lined up on the same diagonal are all examples. The pieces guard one another, so none is left loose, and every move adds to a shared aim.
You can see it in plans. Instead of asking where one piece should go, ask which targets exist and which pieces can reach them together. Doubling rooks on a file, building a battery, or bringing a knight to cover the square a bishop needs are coordinating ideas. In defense, coordination appears as pieces that guard one another so a single attack cannot break through.
Poor coordination is easy to spot. Pieces sit on opposite wings, a rook has no open file, and the bishops block each other. In that situation, even an extra pawn may not help, because you cannot bring force to the right place.
A typical mistake is to improve one piece repeatedly while the rest remain at home. Check the whole army before spending another move on the same piece.
Compare it with Piece domination. Piece domination is a position in which an enemy piece cannot move without being captured, because your pieces control every square it could go to, so it is stuck and out of play.
Also worth reading is Tactical play. Tactical play is a style of chess built on concrete, forcing calculation, using checks, captures, threats and combinations to win material or deliver mate, where precise variations matter more than long-term structure.
Also worth reading is Worst-placed piece. The worst-placed piece is the piece in your position doing the least, and improving it by rerouting it to a better square is a standard way to make progress when no immediate tactic or break exists.
Where "Piece coordination" fits your own play is easier to judge with a coach reading your games; the first lesson is a paid one-on-one review that ends in a written plan.

Piece activity describes how much influence a piece exerts, measured by the squares it controls, the targets it eyes and the freedom it has to move, so an active piece is worth more than its nominal value.
Development means bringing your pieces from their starting squares to active posts, usually by moving the knights and bishops out, castling and linking the rooks, so they can all contribute to the fight.
A battery is two of your pieces lined up on one file, rank or diagonal, with the rear piece backing up the front one so that both press on the same target.
