Plan
Personal productivity is based on planning. Break a big project down into small steps. Many people feel that daily planning doesn't help, it just wastes time. But when you see a complete list of things to do in a limited amount of time, you'll move faster.
Prioritise
A business is a never-ending stream of tasks to improve it. Or saving it if things are going badly. You need to focus on the most important and urgent tasks first. If you don't deal with them, the rest won't get done.
Prioritising, urgency and importance of tasks can be helped by the Eisenhower System. At Binom Kraft we use this system and have already seen its effectiveness. The most important and urgent tasks should be done as soon as possible. Usually these are tasks that have a deadline: deliver a project, respond to a customer, negotiate, etc. Important and non-urgent tasks need to be scheduled. This category usually includes things that will make you and your company better: get training, get your knowledge base in order, etc.
Urgent and non-urgent things need to be delegated. These are usually routine tasks that don't require special skills. The last category is non-urgent and non-important tasks. They should be monitored or removed from your schedule altogether.
