Editing Pair programming (section)

==Pairing variations==
;Expert–expert
:Expert–expert pairing may seem to be the obvious choice for the highest productivity and can produce great results, but it often yields little insight into new ways to solve problems, as both parties are unlikely to question established practices.<ref name="ijhcs"/>
;Expert–novice
:Expert–novice pairing creates many opportunities for the expert to mentor the novice. This pairing can also introduce new ideas, as the novice is more likely to question established practices. The expert, now required to explain established practices, is also more likely to question them. However, in this pairing, an intimidated novice may passively "watch the master" and hesitate to participate meaningfully. Also, some experts may not have the patience needed to allow constructive novice participation.<ref>{{cite book|title=Pair Programming Illuminated |author1=Williams, L. |author1-link=Laurie Williams (software engineer) |author2=Kessler, R.  |name-list-style=amp |publisher=Addison-Wesley Professional |location=Boston |date=2003|url=https://books.google.com/books?id=LRQhdlrKNE8C|isbn=9780201745764  }}</ref>
;Novice–novice
:Novice–novice pairing can produce results significantly better than two novices working independently, although this practice is generally discouraged because it is harder for novices to develop good habits without a proper role model.<ref name="costs-benefits" />
