Serco with botch this...
Like they botch everything else.
I've both worked for and Contracted to Serco for 4 years in total, I can tell you that they are not geared up to be a reseller, they dont understand the business because they work on low margins and services, they do not know how to sell products. The best thing that Serco can do, is leave this business completely alone to run itself, but that isn't what will happen, some management bigwig will walk in, impose "Serco Culture" on the company, lower the Margins to make the business "More Competitive" and in doing so, the profit of the business will drop out of the floor and it'll collapse, much like what happened with ITNet.
Serco is doing this, because it wants to provide IT Services to US Government, it's got aspirations to be the next EDS and a it has a few UK Government IT contracts in it's bag, most of which are run appallingly, although no more appallingly than their nearest competitors.
If Serco wants to stay successful, it should stick to Trains, Prisoners and Maintenance Services.
