The consumer's level of involvement can lead to two types of buying decisions: limited problem solving or extended problem solving

Explanation:

limited problem solving:

It is a problem solving process in which customer is only willing to put very little effort to make a purchase decision in order to fulfill his want or need. Purchaser uses simple decision rules for reaching a a purchase decision with minimal research done. He is not much concerned about the best solution and has limited resources and time for searching information and assessing each alternative thoroughly.

For example: you need a new pair of joggers for gym.  You are already have an idea about joggers and know about new available materials and attributes. So you might do a bit research online and come to a decision comparatively quickly. You might consider your favorite outlet instead of searching for the joggers at every outlet. So you take buying decision limiting involvement in this process.

extended problem solving

In this process the costumer attempts to collect as much information as possible, and thoroughly assess and evaluate product alternatives. So in this situation buyer don't have much idea about the product brands, attributes and characteristics to access the product. Purchaser will research, differentiate and put a lot of effort for taking best buying decision that will fulfill his needs. prior to purchasing the product, he might visit various outlets, research online, search for reviews and suggestions, take information from outlet staff. about the product Marketer should provide with such information to customer.

For example high value items like car, a house etc. Such items are not purchased often so the consumer will invest a lot of time in research and comparison in order  to take the best decision.
