When designing and maintaining large scale software architecture, certain rules need to be adhered religiously. In the absence of which the software starts degrading, maintenance becomes difficult, adding features becomes a nightmare and soon everything comes crashing down as a house of cards.

• Tiering/Layering your logical architecture – a clear logical separation between different layers lead to simplified code navigation and comprehension. The layers should also follow a strict and clear naming convention for all packages and types. One can make of tools to make sure the code follows the logical architecture and all dependencies are in order.
• Cyclical dependency – Adhere to the principle of well defined and cycle free application. Cyclic dependencies can soon lead to bloating of code. Even package should be validated for any cyclical dependencies
• NCCD (Normalized cumulative component dependency) is another factor that needs to be adhered. NCCD of compilation units must not be bigger than 7. If this value grows over the threshold, one should isolate layers and subsystem by only letting them have interfaces as entry points. Breaking cyclic dependencies can also shrink this metric considerably.

In today’s world, whenever you are facing a problem, the first impulse is to open Google and see if other people had already faced the similar problem and how they did they resolved the same. The good part is you are most likely to find the solution to the problem also. Does that mean, Google is the new Knowledge Manager for your enterprise?

Why do the employees tend to search on Google/Bing for solutions and not look at the KM systems?

Healthcare Sector in India is poised to grow to $280 Billion USD by 2020. The investment required in the next 10 years is to the tune of $86 Billion USD, majority of which will be contributed by the private sector.
