TYPO3

TYPO3 is great if you need to connect some systems in company to work together: like ecommerce + CRM + ERP + MRP and build an Extranet for partners/dealers where they can order your products, see particular BOM (bill of material), paid/unpaid invoices and use email marketing on top of it. You can do it but keep in mind that you will need a dedicated hosting, well organized admin(s) and some handwritten code. For simple blog TYPO3 is also a good choose, but WP would be better I think.

Incentivized

• open source - do what you want, and even if you dont know how to do it - someone will do it for you
• more secure than others (Joomla, WP, Drupal) - thanks to dedicated Typo3 Security Team
• modularity and diversity - a lot of plugins/extensions
• workflow and user roles - feel free to build a workflow templates ie. for documents routing
• assets management - no matter is it a video, audio or text file, you can REALLY manage it.
• typoscript language - sometimes JS is not enough

Incentivized

• compared do Wordpress - far less community support
• when you run a simple blog - it is simple as piece of cake. But if it is a large news site, with many user roles, extensions and permissions - it may be hard to find an admin that will organize and keep that stuff working.
• server resources: so you want performance and speed with all that modules enabled? make sure that you have dedicated server in most cases. WP works much better here.

Incentivized

• more complex and elastic revoke system (undoing changes for multi-administrator systems) PHP/JS and TypoScript language
• LTS - long ter msupport (bugfixes and updates)
• usage rights and permissions (much more advanced thatn in WP/Joomla)
• separation of design and content (in WP also but here is complex)
• many plugins to integrate with external systems
• several portals may be operated from a single admin/install

Incentivized

• + 1 platform that handles connections to 11 external systems (CMS, CMR, ERP, MRP, accounting, controlling, email marketing etc.)
• + still lower TCO than commercial systems (Oracle, Microsoft)
• + LTS - long term support - can provide you an updates or bugfixes
• - resource consuming (forget about shared hosting in large projects)
