ok..in that case..Visual representation of how a firm intends authority, responsibility, and information to flow within its formal organizational structure. It usually depicts different management functions (accounting, finance, human resources, marketing, production, R&D, etc.) and their subdivisions as boxes linked with lines along which decision making power travels downwards and answerability travels upwards. Also called organizational chart.
You can make the chart more easy to understand by subordinates and the reporting person..clearly mention the name of the employee and followed by the designation..if the designation is not filled then just apply designation only..make the alignment properly and the boxes should be in sizes according to the levels.
make the top level bit highlighting so it can be easily recognized..if project engg holds the same level u can fix it in one single box it self..no need to mention as seperate if they hold same designation..
the level makes the significate role in the chart..hope it will help you..
