Thanks for the FAQs, they were very helpful, simple and straight forward. Well done.
Cheers
On the first answer of your question, what is pattern?,you have given an example where you mentioned
problem: space
solution:consultation with kitches decoraters
but is there any context?
thank you
Also for the last question how can one recognise pattern or not? I will say a pattern must have been used at least three time and have positive consequences.

Hi Navraj...thanks for your query
In question 1 I have given an example of a Pattern and if you read the example carefully I have also mentioned that in oder to overcome spacing problem, kitchen decoraters will have designs to accomodate customers various needs.
Lets hope that I have answered your query. Thanks
Goodday.
Hi Navraj....before a pattern can be used at least three times it must first be executed and used for the first time so that it can reach the count of using the 3rd time.
Thanks.
Goodday.
i like your FAQ straight forward and very simple, please add more so that the new user of pattern will take it more serious. And for the example you gave nice one but the context is missing.
Hi daljit,
I have gone through your FAQs. You have briefly explained your answers. However, the answer for the last question is partially correct as a structured way of RECURRING problems is when you identify a pattern.
good work :)
