There's a distinction to be made here between the national party organization (i.e. the DNC) and the various state party organizations. Even if the national party gets its act together 100%, the state parties have a fair degree of independence, and the national party has a limited number of levers to force them to do things the way it would like.
In this case, the tech firm was contracting directly with the Iowa Democratic Party, not with the national DNC. So the question here wouldn't be the tech competence of the national party, but of the specific state party that let the contract.
