Wasps Director of Rugby Dai Young says the 17-12 win over Newcastle at Kingston Park proves his side are capable of rolling their sleeves up and grinding out results.
It was not a classic encounter in the wind and rain but Wasps did enough and were comfortably heading for victory at 17-5 until Newcastle's Will Welch grabbed a last-gasp try to salvage a losing bonus point for the Falcons.
"We are still a work in progress but we proved today that we can roll our sleeves up and battle it out," said Young.
"Newcastle is a difficult place to come but I'm pleased because for long periods we had to defend and when we had chances we took them."
"Last season we lived on scraps and there was only one way we could play. This season we've have to develop a different style and a lot of our X-factor players have been out for big parts of the season so we have had to be a little bit different and a bit more conservative in our approach and play the game a little bit tighter."
Newcastle boss Dean Richards lost two players to illness just before the game and two others had to play despite being ill.
"Not the best of preparation," said Richards. "And while I'm pleased with the bonus point, I'm not happy with our first half performance when we should have made better use of the wind.
"We just couldn't make it happen in the first half and that was very disappointing."
