Already planning Samoa's rise, Tietjens said it starts with finding consistency.
"It's about getting them up and producing consistently in year one, in year two it's about the Commonwealth Games."
An appearance at the 2020 Tokyo Olympics is also on Tietjens' radar, after the Samoan team failed to qualify for the 2016 Rio Olympics under Fuimaono Dickie Taufua.
Tietjens speaks highly of Samoa's talent, and will be hoping to emulate the homegrown success of the gold medal winning Fijian team.
"They are very, very talented; they understand the game of sevens no different to Fijians," said Tietjens. "I think what advantage Fiji has is they have just thousands of players, they don't have that volume of players that play sevens in Samoa but they have some very talented players that do live here on the island and we will provide them with that opportunity."
Although Samoa may not have state-of-the-art resources at their disposal, Tietjens backs his side's work ethic above all else.
"It's not everything about resources, if there's one country that's really resilient and they lack the resources it is someone like Samoa.
"What I've seen in the last couple of days, they're providing a massive effort into training. Yes, they mightn't have brilliant facilities, but I've always said you can't coach ticker and these kids just want to learn, they want to do well and of course it'll come."
After 22 years of shouldering high expectations in New Zealand, Tietjens is still aiming high.
"A lot of that expectation has eased now, there's a real challenge, I'm excited by it, and that's helping a country that doesn't have the resources be a better sevens playing nation."
