I want to know the answer to the following question:
Dell lagged behind Hewlett Packard and Oracle in delivering what kind of solutions?
All the background I'm provided with is that "Dell had done well with a horizontal organization that focused on PCs when the computing industry moved to horizontal mix-and-match layers in the 1980s, but by the mid-2000 the industry shifted to vertically integrated stacks to deliver complete IT solutions and Dell lagged far behind competitors like Hewlett Packard and Oracle.". Is that enough to answer the question?
