B.1.5.EW:3 - Forces

• Familiar constituents make work possible, while their combination can introduce a difficulty absent from separate practice.
• Encompassing requirements constrain the parts; the parts’ actual capabilities limit what the whole can achieve.
• One action can serve several wholes, whose conditions can differ or conflict.
• A short account can guide action; unnecessary decomposition consumes the attention needed to act.
• The whole may be ongoing while only some of its constituents are active.
• A planned connection helps design work, but actual enactment needs the performed connection.
