FIVE FORCES
Bargaining power of customers (the members)The 'switching cost' is to high. If a member leaves the WTS, he/she will suffer from being disfellowshiped and loose friends and family.
People find new friends. Just like how the RCC abandonned my grandmother when she joined the JW church and she found new JW friends, I've found new XJW and Never-Been friends.
Bargaining power of suppliers (the apostates and other denominations)
The apostates don't really have a tangible product to substitute the WTS product. All they can do is try to prove the WTS is wrong, that's about it.
Actually, we've found other tangible products, some here are ministers in other churches, others are great figures in their communities, and still others are pagans and secularists.
New entrants into the market
There are no new religions around to match the WTS product.
Haven't you heard of the Seventh Day Adventists? They're pretty much the same religion as the JW's, except one is unitarian and another's trinitarian. Not to mention the 2X2 religion, other adventist sects and the Unification church (All, ironically share dangerous charachteristics with the JW's.)
Substitute products and services
Substitutes products (hellfire, immortality of the soul, trinity). JWs have learned to reject these doctrines. It is hard to deprogram them to embrace it again.
And assuming they're going back to Christian religions, yes. But that's the thing, Christianity isn't the only faith that's out there.
Existing competitors
Roman Catholic Church, Mormons, Seventh Day Adventists, Salvation Army. JWs are programmed to view them as false religions. It is hard to deprogram them to embrace it again.
Actually, it's not quite uncommon to see XJW's go back to those same churches. On this board in fact, we have many fundimentalist Christians (Don't worry, we're working on getting them to the good side :P).
Medicine on their sideExcept in times of dire need. It's estimated that over 50K JW's have died from a lack of blood over the past few years. And a lesser %age of that has had their lives saved because of the no blood policy.
For the blood issue, alternatives are coming up and the field of medicine is now buying the idea of bloodless surgery.
Past mistakes of interpretation
The JW GB are now vocal in their admission of the past mistakes they did. After all, they are only humans.
Sir, before you have me heading off to the hospital for breaking my legs while falling on the floor laughing, you should read this site. http://quotes.watchtower.ca . Has all the WT quotes from WT history, like the time they played nice with the Nazi government, etc.
Management style As the management is changing and getting younger in terms of age, old 'beaucratic traditional culture' is slowly changing to a more relax management style.
What you've proved is that you have no idea about buisness rule #1, which is know thyself and thy enemy. You assume that your "enemy" is a religious denomination that's only goal is to preach against the JW's and "thyself" can be taken for their word. Therefore, your buisness model that you mentioned is going to fail no matter what. And it is failing. As of right now, the WT is hemmoraging members in developed countries (Ironically, the countries that have the internet, where dangerous sects are exposed daily) and when news gets around the developing countries, they're also going to hemmorage members too.
If I have a buisness, I would want a buisnessman like you to stay far, far away from it. You'd make me poor.
