A resource audit is a technique for identifying and evaluating the resources that an organisation has or needs to achieve its objectives. It helps to assess the availability and quality of an organisation’s resources, such as human, physical, financial and intangible resources. Therefore, option C is the correct answer, as it identifies which of these would be considered as ‘tangible’ resources in a resource audit. Tangible resources are resources that have physical existence and can be seen or touched by human senses. Examples of tangible resources are machinery, equipment, buildings, materials, money etc. Option A identifies ‘a’ (recent investment in new machinery), ‘c’ (the number of staff currently employed in the company) and ‘e’ (the company has significant retained profits) as tangible resources in a resource audit. These are correct examples of tangible resources in a resource audit, as they have physical existence and can be seen or touched by human senses. Option B identifies ‘b’ (feedback from customers and an increase in sales), ‘c’ (the number of staff currently employed in the company) and ‘e’ (the company has significant retained profits) as tangible resources in a resource audit. These are incorrect examples of tangible resources in a resource audit, as ‘b’ (feedback from customers and an increase in sales) is an intangible resource, not a tangible resource. Intangible resources are resources that have no physical existence and cannot be seen or touched by human senses. Examples of intangible resources are reputation, brand, knowledge, skills etc. Option D identifies ‘c’ (the number of staff currently employed in the company), ‘d’ (the ability of EcoBags to respond quickly to new market demands) and ‘e’ (the company has significant retained profits) as tangible resources in a resource audit. These are incorrect examples of tangible resources in a resource audit, as ‘d’ (the ability of EcoBags to respond quickly to new market demands) is an intangible resource, not a tangible resource.
