Innes will report to Eddy Reynolds, head of adviser and investment proposition and joins from Threesixty Services where he was head of consulting and M & A support.
Innes' main role will be to help adviser firms grow and add value, while reducing cost and risk in their business.
Eddy Reynolds said: "Our relationship with advisers is key to the success of our business and we recognise the environment they are operating in is becoming increasingly complex and challenging.
“We want to work with advisers to provide the solutions and support to help them develop their business into profitable and efficient organisations. Innes' experience makes him perfectly suited to the challenge."
Key areas that the business solutions package include:
 Brand and communication support, including marketing
 Client management
 Operations management
 Financial management
 Risk and regulatory management
 People and talent management
Innes Miller said: "This is a really exciting opportunity for me. I will be working collaboratively with adviser businesses to understand their needs and will develop solutions based on their feedback. Standard Life's proposition for advisers is already an attractive one, and the delivery of business solutions is the natural next step."
