Avaya seems to consistently miss the critical element: Build a product that customers love. There are obviously many other factors that feed into it, but if you don't invest in the core product that seamlessly then leads to OUTCOMES for a customer, there's no point. You can't put lipstick on the pig year after year (no offense to pigs) and expect different things to happen. The successful vendors in the space, small and large, have all realized that, and plow a [relatively] high portion of budget into core product and industry. I'm not sure if Avaya is 'salvageable' still at this point and if people even want the parts (I was part of a Fortune 10 that looked at acquiring it and the parts didn't even make sense to make a play for), but if there is any hope, they better knuckle down and focus on what is important.
@5tuo+1iDzyNQ3 said it perfectly.
