Looking for New Business Ideas

When looking around for business ideas, bear in mind that these could be based on any of the following approaches:
A manufactured product where you buy materials or parts and make up the product(s) yourself.
A distributed product where you buy product from a wholesaler/MLM, retailer, or manufacturer.
A service which you provide.

You should narrow your search to specific market or product areas as quickly as possible. For example, the "food business" is too broad a search area. Do you mean manufacturing, distribution or retailing, or do you mean fresh, frozen, pre-prepared etc. or do you mean beverages, sauces, confectionery etc.? It is better to pursue several specific ideas (hypotheses) rather than one diffuse concept which lacks specifics and proves impossible to research and evaluate. Generally, you should always aim for quality rather than cheapness. Be very cautious about pursuing ideas which involve any prospect of price wars or are very price sensitive; of getting sucked into short-lived fads; or of having to compete head-to-head with large, entrenched businesses.

To locate ideas, observe consumer behavior:
What do people/organizations buy ?
What do they want and cannot buy ?
What do they buy and don't like ?
Where do they buy, when and how ?
Why do they buy ?
What are they buying more of ?
What else might they need but cannot get ?

Also, look at changing existing products or services with a view to:
Making them larger/smaller, lighter/heavier, faster/slower
Changing their color, material or shape
Altering their quality or quantity
Increasing mobility, access, portability, disposability
Simplifying repair, maintenance, replacement, cleaning
Introducing automation, simplification, convenience
Adding new features, accessories, extensions
Changing the delivery method, packaging, unit size/shape
Improving usability, performance or safety
Broadening or narrowing the range
Improving the quality or service.
