You work for a company that is running a project for another company that is not familiar with project management. In fact, your customer has never run an initiative as a 'project' before, so they are completely unfamiliar with the formal processes of risk and change management, and the concept of quality management beyond simple 'testing' (among other things).

You are in a meeting with senior people from the customer's company. Explain why it is important to do organized, well-thought outrisk, change and quality management. REMEMBER... these people don't care about project management 'definitions. They care about why doing this is beneficial to them. Answer in terms that would make sense to them.
