So what happens when a company is brave enough to introduce Scrum into a CMMI:5 environment




Here's what Jeff found:
- Productivity doubled in less than six months reducing total project costs by 50%.
- Defects were reduced by 40% in all Scrum projects (despite the fact this company already had one of the lowest defect rates in the world.)
- Planning costs were reduced by about 80%.
- User satisfaction and developer satisfaction were much higher than comparable waterfall implementations.
- Projects were linearly scalable, something never seen before. The productivity of individual developers remains the same as the project increases in size.

this is good for specially with  small organization to analyze their data without buying any OLAP systems.

Which JavaScript Framework should I Used for Single Page Architecture?




Following Comparison from Steven Sanderson.




Disagreement: What’s flexible, what’s integrated.
Each technology has different levels of prescriptiveness:
Views
URL routing
Data storage
AngularJS
Built-in DOM-based templates (mandatory)
Built-in (optional)
Built-in system (optional)
Backbone
Choose your own (most used handlebars.js, a string-based template library)
Built-in (optional)
Built-in (overridable)
Batman
Built-in DOM-based templates (mandatory)
Built-in (mandatory)
Built-in system (mandatory)
CanJS
Built-in string-based templates (mandatory)
Built in (optional)
Built in (optional)
Ember
Built-in string-based templates (mandatory)
Built-in (mandatory)
Built-in (overridable)
Knockout
Built-in DOM-based templates (optional, can do string-based too)
Choose your own (most use sammy.js or history.js)
Choose your own (e.g., knockout.mapping or just $.ajax)
Meteor
Built-in string-based templates (mandatory)
Built-in (mandatory?)
Built-in (Mongo, mandatory)
Spine
Choose your own string-based templates
Built-in (optional)
Built-in (optional?)
As expected, whenever a library leaves a decision open, they argue it is better overall to guarantee composablity with arbitrary 3rd-party libraries. And the obvious counter-argument is that integration can be more seamless if built-in. Again, based on my conversations, the audience was split and opinions went in all directions — usually based on how much other technology stack an individual was wedded to.
Quote from Tom Dale of Ember: “We do a lot of magic, but it’s good magic, which means it decomposes into sane primitives.

The Contenders

Here is a table showing all of the frameworks support for the above features. Click through the title for more detail.

Backbone.js

Sammy.js
Spine.js

Batman.js




I am still not in a position of choosing any of them for my single page architecture applications whereas my sense with Angular.js.
will see. 

cheers !!!
