If you are getting some product or even website developed then you would definitely like to track all the developments. You would also like to comment on the work done particularly if the things are not going your way. For this productive feedback you need a Mockup to inform your designer about the appreciation or criticism of the performance till date. In this case the designers often play trick on the clients and ask for the feedback at the early stages of the project. In this case it becomes quite difficult for the clients to exactly understand the shortcomings and they are not able to pass the remarks. Moreover, the Mockup the users are provided for commenting is of low quality which again makes it difficult to comment on the project. The designers can keep the cost of these feedback tools low by getting them developed in cardboard to ask the client about the usability and functionality of the work done.
Another advantage of using the Mockup is that any alteration can be made in the project right at the stage when it is raw and this saves the time from making unnecessary additions and deletions in the final work. This satisfies the clients as they get the final product as per their requirement. A Mockup acts like a discussion medium between the user and the designer of the product and gives an opportunity to all to work in good atmosphere with no difference of opinions.
