Custom development alludes to the development of software that is well-defined and separate from Commercial-Off-The-Shelf (COTS) bundled software or existing bundled open-source software. Custom development either makes another application or upgrades the functionality of a current application. It tends to be finished by either in-house developers or by external contracted developers.

Here are few best practices related to custom development, have a look:

Custom developed software should utilize the standards of Modularity and Reusability.

• Modularity: Software should be written in a way that takes into account proficient reuse by developing APIs for normal functionality, utilizing object-oriented paradigms, commenting code, and where and where the proper archiving code to depict higher-level operations.
• Reusability: Before building a solution a survey of existing code ought to be directed and candidates for code reuse ought to be recognized and evaluated. Duplication of code should be evaded when conceivable.

At the point when in circumstances involvement has esteem support in software communities is encouraged.

Communities that are not vendor-driven are favored and this involvement ought to give the following advantages:

• Improved Knowledge for the representative
• Strengthened Skills for the representative
• Networking and peer knowledge
• Connecting WP plugins with 3^rd Party APIs
• Visibility for UNL

Tiered Architecture isolates client communications, handling, and data persistence into different and distinct layers. Most of the time separation is physical however, separation can also be logical as well.

MVC classifies interactions, processing, and data handling over three different areas:

• Model
• View
• Controller

Vendor bundled won’t be customized without plenty of sufficient and approval.

If vendor package customization is essential the steps needed to apply the customizations will be clearly documented and maintained. When a vendor releases an advanced version of their software this documentation will admit the customization to be applied to the updated version.

Here are a few Advantages of Custom Application Development:

• Automate repetitive tasks
• Facilitate collaboration
• Everyone can access the data they need
• Security
• Maximize technology investment
