IMHO Transparency improves efficiency, innovation and is one of the few defences against bad managers and systemic problems. Within an organisation I personally think its good. on certain occasion you may have need to develop things in secret (from the public or internally). you can create isolated teams with open communication within them and clear rules about what is communicated externally - but open rules about why. Full disclosure though: I probably have base philosophy that tends towards believing labour and decision making have value and that knowledge cannot be owned or have value out with its application; this leads me to not want to long term invest in structures that rely on trying to stop or control the flow of information. Basically I would see it as an indicator that a business model is either unsustainable or exploitative if it relies on this beyond things like project teams for new tech / HR sensitive changes. Well to be fair the more common reality is that this is an indicator of management / governance issues, as keeping the details covered up is great way to hide failure. EDIT: Specifically on Hype - I dont think this is the deciding factor, you can have lots of hype around open and secret projects. I would personally make the secrecy decision on the chances that i am going to be beat to market or out-advertised by a bigger player copying the idea (and other similar risks that may be specific to the project).
