Final answer:
A 'change order' or 'design directive' is the term for a verbal instruction to modify an aspect of a design by an architect or designer. These changes are guided by the principle that form follows function and can arise during any design phase for a variety of reasons.
Step-by-step explanation:
The term used for a verbal direction from an architect or designer to change something in the design is often referred to as a 'change order' or 'design directive'. This occurs when, during the iterative process of design and construction, an aspect of the architectural or design plan needs to be adjusted or altered. These changes can arise for various reasons such as new client requirements, unforeseen technical issues, or functional improvements.
Architects and designers work in teams to develop the design architecture of buildings or products. Function is a key component in these designs, with the principle that 'form follows function' being a guiding rule. Designs are informed by the intended purpose of the structure or product, and a range of different professionals such as lighting and costume designers contribute to creating a cohesive design that meets the technical, aesthetic, and functional needs.
During the technical rehearsal phase in theatre production, for example, a director may issue change orders, necessitating adjustments to the set, lighting, or costumes based on how they work together live on stage. Such changes ensure that the final result aligns with the overall vision and functional requirements of the production.
