Business Advantages of Traditional Software Development

All businesses and IT firms will usually need some form of software during their lifecycle. The types of software utilized by most companies vary from applications that will facilitate better management of key organizational functions - Human Resources Department, Finance and Accounts, Inventory and Stocks to be more precise elements of software that have a key purpose such as Content Management Software for use on company websites. Even though these software applications can be bought "off the shelf", there are many business advantages that can be related with choosing custom software development.

Custom Software Development Is Created Uniquely For You
Developing custom software is a tailored made to determine process, which means that any applications and software programs developed as a result of the process will be uniquely made for your company and its specific needs and requirements. Fundamentally a piece of custom made software is flexible and has the potential to fulfill your specifications meaning that it is easy to use and can be deployed throughout your entire organization. Instead of having to make do with a readymade software program or application, with customized software you can be sure that what you will obtain will be entirely fit for purpose. There are also considerable financial benefits that can be associated with custom made software even though it costing a slight more to purchase than readymade packages. Software applications that have been made for you don't require any license fees, so you can distribute them across your entire organization without requiring paying extra.

Basics of Cross Platform Mobile Application Development

The use of Mobile Apps has been immensely increasing in the recent past. There is a lot of possibility for extension in this field. Nearly all principal software companies are focusing on mobile app development. Conversely, time and money are proving to be a challenge.
Frankly speaking an app built for an Android device will not be attuned with other devices, and the efforts are to be continual so as to make that app compatible with other devices. This impelled to the requirement for cross platform mobile apps. These apps bound the efforts of the developer for creating or testing mobile apps on various platforms. The theme of these tools is very easy, the developer can construct apps using any custom language (java or or HTML be it any scripting language). One time the design and execution of the app is accomplished, the developers can use an effortless function to generate the same functional app for any mobile platform version of Android, Blackberry, or iOS or any other mobile platform.

Reusability of code, Cost effective development and easy deployment are some of the benefits of using cross-platform networks. There are diverse cross-platform frameworks available. 

Some of the top ones are PhoneGap, Appcelerator Titanium and Rhodes.
1) PhoneGap: PhoneGap is an open source mobile application framework for building such cross-platform mobile applications utilizing HTML, CSS, and JavaScript. The app helps the developer create applications that can run on multiple devices/platforms with the same code base. Apps developed with PhoneGap can interrelate directly with mobile device hardware like GPS, which are unavailable to normal web apps. These apps can be built and deployed like native applications. PhoneGap supports nearly all platforms such as Android, iOS, Blackberry and Windows Mobile making it the most dominant framework for cross-platform development.

2) Appcelerator Titanium: Appcelerator is known for their innovative product, Titanium, which allows web developers to create mobile applications without knowledge of Cocoa-Touch or Java. Titanium is essentially an API and run-time which allows you to build a web application and deploy it to a mobile device, or run it on the desktop. A Titanium Mobile Web app is intended to be run from a web server. You can effectively run it from a browser as a local file also. The main downside with Appcelerator is that it doesn't have Android Emulator, a virtual mobile device that executes on your computer, which lets the programmers to develop and test Android applications without utilizing a physical device.

3) Rhodes: Rhodes is a Mobile App Development framework from "Rhomobile" that empowers developers to enhance sophisticated mobile apps that could be deployed on all the major mobile platforms like iPhone, BlackBerry, Windows Mobile, Symbian and Android.
Rhodes uses HTML for user interface development. Therefore, instead of having to develop the UI in Objective C, C++, Java, or.NET for each device, one can do it once in HTML and deploy on all the devices. Rhodes is dual-licensed under the GPL and a commercial license. Open-source Developers make their apps by using the GPL version of the framework without any cost. 

To summarize the cross platform mobile development tools are still not considered be solution. Although the majority of these tools are still growing rapidly the mobile platforms are evolving even swifter pace. Major platform vendors are contending against each other to bring loads of functionalities and capabilities to life. You may expect some surprises when testing the same functionality on different platforms/devices. Another significant thing to consider when constructing a new functionality that does not exist in the cross platform may take even more time to its cross platform counterpart. When the application is getting complex and time to bring in new enhancements, you cannot assume it would be breeze anymore.

Even though it is better to build proof of concepts and prototypes using these cross mobile frameworks, we should better estimate the nature of the app, users of the app, performance requirements and ease of maintenance and adapting enhancements.

Why Re-Engineering And Software Testing Are Critical For A Firm?

Testing of software is imperative as a few errors and faults are inevitable. Software developed will be put to testing procedures to look for as many faults as possible to make sure that a standardized product with least number of errors is delivered. The software testing team has majorly a couple of primary responsibilities
  1. To recognize the defects and ensure that the software is error free
  1. To confirm the software would be able to successfully meet the user's requirements
To sum it up it is the key goals of the testing team are to recognize errors, non-coherent and threats related with the product and communicate the same to the development team so that all the defects discovered are taken care of and a high class product can be delivered to the client.
Testing is not a single time activity. It needs to be carried out over the entire life cycle of the software. There are several reasons for which software would need to be tested again. Any changes big or small like version upgrade, enhancement or module addition, deployment at a new client site and addition in the number of users require the software to be re-tested to make sure that it is bug free.

Why re-engineering is required?
As quoted before as the software keeps on changing there is a need for altering the software applications and products as well as they need to be re-tuned to comply to the changing requirements. As the software firms constantly attempt to meet the customers' demand they also need to make certain that the software applications are often and continuously updated to keep pace with the challenging and competitive business world. In the elementary words re-engineering could be described as renovation. For e.g. If a program is written in an old programming language this would limit its functionalities. Now, if the same program is re-written in a language more relevant in today's time it would increase the functionality. 

Listed are some of the acumen why re-engineering is requisite in an organization
  1. Pricing - Old software systems maintenance cost is high
  1. Performance Issue - Improved performance of the re-engineered software acts as a huge incentive
  1. Operation and flexibility - New and revised software system would be more agile and effortless to use
  1. Data storage necessities - As the firm grows the data also grows. Increasing quantity of data create a need for the organization to revamp its existing systems and software
  1. Altering technology trends - It is essential for a business to stay in tune with the changing technology trends and update its software accordingly.
Re-engineering or migration can be a modest challenging as the company's information and data can get vulnerable in the process.

The business needs to come up with a solid testing strategy to ensure conformance, completeness and agreement.
