Become a quality.com.au consultant
Anyone can be a consultant. Just hang your shingle up on LinkedIn, and now you are one. But not everyone can be an approved quality.com.au consultant. If you are already consulting in your chosen field and looking to expand your service offerings, then going on the journey to be an approved quality.com.au consultant is rather a simple process. More details are on this link.
Making the change from employee to independent subcontractor is a little more challenging. You need to be and act businesslike. You need to walk the talk of the process you are consulting in. You need to be an absolute zealot for quality management systems, continual improvement, and client focus. You must also be prepared to have your business examined in the same manner you wish your clients success.
Just remember: if it were easy, everyone would do it. But if you were shown how the opportunities would present themselves.
