Wales Under-21s begin their 2015 European Championship qualifying campaign against Moldova.
Wales have gone close to reaching the finals in two of their last three campaigns, but they only finished fourth in their group as they came up short in their efforts to reach this summer's showpiece in Israel.
But former Colchester boss Williams enjoyed his first win in charge with the 3-0 victory over Iceland last month, handing out seven new caps in the process.
Wales are the second seeds in Group 1, behind favourites England, but Williams is not setting targets for his young group, and instead wants to see further development from their performance in Llanelli.
He said: "Last month was very positive, we have tried to impose a new philosophy on the players and the win was a very good start.
"It is good for us to start our campaign on the back of a win, but the best part for was we look like we knew what we were trying to accomplish as a team.
"I have been encouraged by what I have seen and I hope that continues against a Moldova side who will be a good test and have some very decent players."
But Williams will have to do without Crystal Palace's Jonathan Williams, who was man of the match in the win over Iceland.
However, the manager is more than happy to see the midfielder get his chance with Chris Coleman's senior side.
He said: "Jonny is a top class player and we are always pleased to have him, but this is all about Chris Coleman's team and we want our guys to push on and get in the first-team squad.
"If he features this time around it would be fantastic and someone else will get an opportunity in our squad.
"I hope he pushes in and gets a cap, but of course we will miss him."
