How to solve problems at work
First, develop a ranking system for your tasks in terms of the level of importance. When getting the task, take for yourself the rule to immediately determine its importance: paramount, high, ordinary. To fulfill the paramount tasks, proceed immediately, the rest can be postponed, but be sure to set a deadline for their fulfillment. If you are keeping a calendar of tasks in the mail, then it's still simple. You can, for example, set reminders or mark tasks with colored flags.
Any task, from complex to simple, can be divided into subtasks. Then the solution will be easier. When you finish any stage of the task, show the results to the management. Ask whether in the right direction you are moving, perhaps the course should be changed. If you set the task yourself and consult with the leadership is not necessary - the easier. But do not forget about self-control and timing - these are the two most important components that determine the success of solving work tasks.
If the task is so complex that it requires the involvement of employees of other specialties, do not hesitate to talk about this to management. It is not necessary to take on the task, you can not cope with which on your own. It is better to argue reasonably with the authorities, why do you think that you may need the help of other employees.
