Qualification for last summer’s Euros was the first time Northern Ireland had ever reached the finals of a major competition.
They followed that up in September by completing their World Cup qualifying campaign with away wins over Luxembourg and Latvia, before an impressive home victory over Italy in a friendly in November.
Shiels’ departure and the lack of a camp in February created uncertainty around the senior team but Platt added the decision was made with the long-term future of women’s football in Northern Ireland in mind.
“I think it is unrealistic that we will have someone in place by then [the Wales match] but we certainly have interim plans in place to make sure that we have that covered for the senior women’s squad as they take that friendly against Wales,” added Platt.
“We are looking forward to regrouping then and we can build forward from where we are.”
Asked if she would like the new manager to be a woman, Platt said: “We are certainly looking for the best person for the job, irrespective of gender. If it happens to be a woman, great. If it happens to be a man, that is great too.”
She added: “However, if you were to ask me would I like to see more female coaches coming through our system and supporting them within that structure, of course we would. And that is certainly one of the things that is on my agenda.”
