Applying best practises and project management standards. Planning and transition management are the key to success.
Too many projects share a common denominator: They take longer, cost more and offer less than planned. Using project management standards, adding experience about what does works and what does not, and defining a methodology that guides and supports, leads the project to success.
Project management is the means to achieve the objective. And not the other way around.
A project is only successfully completed when it works; in time, in budget, in scope and is supported by the stakeholders.
