What We Do

Expert Advice has a suite of products and materials to suit every need.

Our Books

The Concise Advice series was invented by Kevin Duncan and his publisher. It now contains over 40 books, nine of them written by Kevin and Sarah. Unlike most business books that are too long and padded out with too much material, these books take the full wisdom of wide-ranging business reading and reduces concepts down to their pithy minimum, typically on one spread. This allows the time-pressed executive to grasp ideas at speed and put them into practice straightaway.

The handy pocketbook format is ideal for training, note-taking and idea generation on the go. With their highly visual format and minimal copy, the books have a wide international appeal and have been translated into over 20 languages. Sales to date are around the 200,000 mark. Grab a hard copy, or a digital one, use them for team sessions, look at the training, or ask for an in-person session.

Our Training Programmes

Each of the eight business books, has its own training programme. Plus there are four more blended workshops that combine the best of two books, in different combinations. A dozen schemes make up the full set.

Every training topic is the full package. All attendees receive the book(s) relevant to the topic, plus a full set of charts and supporting notes. Each book has a supporting blog with videos, podcasts and articles. The topics are available in a range of formats, including in-person, online, all-day and bite-size versions.

Between us, we have run thousands of sessions and trained over 10,000 people, so the formats are proven to work, and the satisfaction scores are always high.

Our Business Library

The Expert Advice products represent over 60 years of business experience.

The engine that drives all the thinking is our Business Library: Greatest Hits – probably the world’s biggest free business library, which summarises over 450 books.

This has been a labour of love for 20 years. Over 20 million words read, with all the books summarized on one page. Categories span leadership, behavioural economics, ethical strategy, creativity, innovation and much more.
