Four areas I can think of.

1) Showdown equity locked in: Calling gets us all-in and we need pot odds to justify the the call based on our equity against our opponents range.
2) Implied odds situation: We think are currently behind, but we have outs to a hand we deem better than the opponents range. Against some part of the opponents range we won't be able to extract value, against other parts we will be able to extract a great deal of value, against some part of the range we will build a big pot and split, and against yet another part of the range we'll build a big pot and lose to a better hand. Stack sizes are crucially important as well as analysis of opponent tendencies - especially with each of the types of hand in his range that we hope to extract value from.
3) Reverse implied odds situation: We think we are currently best, and that if we call the bet we are also most likely best - but continued aggression on the river would narrow the opponent range towards hands that beat us. With large enough stack sizes the question can become that with 3,4 or 5 betting on turn or river we might suddenly find the range we play against to be beating our hand, but since flatting is an option for us at any point the worst case we need to consider is probably putting in $10 on the turn and $35 on the river to win $50 against a range of hands strong enough to bet both turn and river.
4) Steal equity: Calling the turn to steal on the river. A certain stack size is required for this to be effective. An alternative here is to raise the turn if opponent tendencies are such that this is more likely to be respected as strong. Steal can come in the shape of a bet, raise, check-raise, bet-3bet etc as stack sizes allow - or as the oversized shove. The important things here are consideration of your opponents capabilities, your image, your opponents likely range for you, the opponents likely hand (any weakness in his line to this point?), your opponents ability to lay down a second-nut hand or other hand good enough for him to bet strongly on turn and river etc.

Interesting about this hand is also that we don't know what limit this is. $15 pot and a $10 bet - is this 10nl in a hand that was 3bet aggressively pre and c-bet big on the flop? Or just raised pre and check-raised on the flop? Or did it see a sequence of puny near-min raises? Is it 25nl with a raised pot multiway to the flop where just one person called the cbet? Who took the initiative pre and post? Who has been making bets and who has been calling them? Is this 50nl? While it is important to know the stack of money behind, it is also important to know the size of the big blind, to give us some idea what kind of action has seen us to this point and what that tells us about the likely hand ranges.
