Identify the importance of coordination that is depicted in the lines "it arises out of the complexities of modern technology and the diversity of tasks to be performed".

Option 1: Specialisation -> Modern technology's complexity and diverse tasks require specialized skills and knowledge, creating interdependence that necessitates coordination among specialists.

Option 2: Growth in size -> Refers to expansion in organizational scale and workforce numbers, not specifically addressing technology complexities or task diversity.

Option 3: Functional differentiation -> Involves dividing organization into departments by function, but doesn't directly capture the technology and task diversity aspect mentioned.

Option 4: Organisational diversification -> Relates to expanding into different products/markets/businesses, which is not what the statement describes.

Hence, Option 1: Specialisation -> When modern technology becomes complex and tasks become diverse, organizations must employ specialists with specific expertise. Each specialist handles particular tasks requiring unique skills. This division of work into specialized roles creates interdependence, making coordination essential to integrate all specialized efforts toward common organizational goals. The complexity of technology and diversity of tasks directly necessitate specialization, which in turn makes coordination crucial. -> correct
