Pick any two...
For most products and services there are three aspects that matter when you order them:
How much time will it take to develop the product?
How fast can the service be delivered?
Will you get it in due time?
How much will it cost?
Will it be cheap or expensive?
Is the scope of the service on target?
Is the product good?
Does the product perform as expected?
In the local markets here in Spain, I have learned that there are a few rules to go by. There are cheap products that magically get cheaper if I act interested and then act uninterested. Seemingly, it's always very important that I buy their product right NOW. I have learned by experience that these products generally have low quality.
