Yes, this. Good management knows that you know your trade and accepts your estimates. Bad management thinks they know better and try to negotiate on estimates.
Over the years I've found that feature development, particularly adding to existing systems, will get better estimates if we're allowed a spike to review the affected areas up front - this is when you discover unexpected dependencies or just sheer awful spaghetti. When you're not allowed to do this up front is when you come across the unexpected gotchas that blow out the best estimate you could provide at the time.
Your argument is that paying customers were given a choice in the matter and so should vote with their feet. Normally I would agree with that assertion except that most ISPs don't offer a choice of modem to customers or even alert them that they have a choice. Often they'll grumble about incompatibility issues if a new customer says, "I already have a modem."
Modems are just another way for ISPs to milk money out of their customers. e.g.: ISPs bulk buy these modems from whomever they can source them for $10 each and then charge customers a once-off connection fee ($80-$100) or ongoing monthly rentals ($10-$20/month).
BrickerBot and their ilk are still punishing the unwary customers for the incompetence of the manufacturers and ISPs.
Some businesses can't help using old hardware or operating systems, because they use specialized software that also hasn't been brought up-to-date.
Nonsense! Virtualize that crap and run everything else on shiny new hardware. I'm sure there are still brain-dead banking applications that require ActiveX controls to run in MS-IE 5.5 or 6.x but that shouldn't stop everything else in the world from progressing.
http://ar5-syr.ipcc.ch/topic_o... does describe solar irradiance and even puts a figure on the estimated amount it provides to the total radiative forcing.
The IPCC doesn't do any such thing. The IPCC Charter and IPCC Document Submission Guidelines forbid it accepting or analysing any material that shows natural climate variability. It is only allowed to accept or analyse documents that show human-induced climate change.
When Enterprise looks at IoT you can bet they're thinking INTRAnet of Things, not INTERnet of Things.
With all the safety regulations on mine sites no sane mine site operator is going to be putting INTERnet of Things VIMS interfaces on their equipment to report running statistics back to their ERP, its going to INTRAnet back to the C.O., maybe traversing the internet via a site-to-site VPN.
Consultants are mystical people who ask a company for a number and then give it back to them.
