Step-by-step explanation:
When planning for a small open office project, the most important consideration is the support of job function and relationships. This encompasses understanding how the design of the space will facilitate the workflow and interaction among employees. It is about creating an environment that enhances productivity and allows for effective communication. Other considerations, such as management of overall cost per square foot, specification of appropriate materials and finishes, and maintaining a good ratio between circulation and work area, are also important but secondary to ensuring the office layout supports the jobs it's intended for.
