Embedded Software Development: Testing Your Software

New designs, innovations, technologies and ideas are shaped every day. Testing is a part and parcel of every design that is created. Especially when it comes to software testing, implementation might go wrong if the software isn’t tested properly. It is very important to test the software as it gives an assurance to the business owners that the embedded software development has been carried out flawlessly by keeping the current trends in mind. Thus, most of the business owners like to get their software tested after the software development is over.

It is very common for the viruses and bugs to attack the system after the software development is done. This might lead to multiple problems like the privacy of the data getting hindered and the system getting hanged. Therefore, it becomes important to scan and debug the system so that the viruses are removed.
Majorly, there are three kinds of testing:

1. System testing: This involves testing of the system as a whole.

2. Unit testing: In this type of testing; the programmer checks every part of source code compared to its description. This testing is very crucial for the system as each part of it is thoroughly verified and tested.

3. Integration testing: The integration testing takes care of the fact that the internal systems interchange data without any problem and confirms whether the system is capable enough to work in-sync with other systems.

4. Other types: There are other types of testing including manual testing and automation testing. Manual testing is done to check the performance of the system and its working. It can be done by anyone working with the system.

Automation testing is done to verify the programming code. When huge data applications have to be tested, automation programming is the best option. These testers types can help the system to work faster and the applications run smoothly.

We are surrounded by many electronic instruments in our day to day lives including mobile phones, washing machines, microwave ovens, computers etc. Most of these devices have embedded software installed in them. Now; no one would like to solve software related problems every day. It rarely happens that the software in these devices goes wrong. This is because most of them are proficiently tested.

It is very significant that the person who tests the software is skilled, experienced and has a complete knowhow of how the software works. One should also check whether the person who is checking the software has been a part of the embedded software development for that particular system. This is because, if he has not created the software, he might not be aware about the loopholes in it. Testing is definitely not an easy job. Thus it is very important for one to find someone who is expert at it.

Return on Investment in Software Development

Hi I thought I would write a series of articles on a topic that I believe is becoming absolutely critical in the software development industry, that being the magical and mysterious ROI (return on investment) in software development.

As the owner of a programming company here in South Africa, I decided at the outset of the company that a rule of thumb for accepting any software development project would be that I would need to figure out how to measure the ROI in that particular project. Now you may or may not be surprised to know that in most instances my clients don’t actually think of this measure before taking on the project, they know that they have a business problem or business need that needs to be solved with technology and are willing to pay an amount of money for that. Experience over the years however has shown me that the best way to retain that client in the long term and or to make more business from that client is to prove a ROI in some way on that software development project.

I find this measure to be critical because for my companies purposes it shows exactly how successful a project is to my client in monetary terms. The bigger my impact through the software I develop, the more successful I have been at satisfying that clients need, the easier it is for me to go back to that client and offer further services. Contrary to popular belief, I don’t believe that a project coming in on time or under cost is a great measure of the success of that project at all, this is typically what IT companies do. If I really want to do a great job for my client then I always intentionally build a monitoring tool into the software I develop for them and that tool must track the ROI for the client in some way and present a report to the client whenever they want to see what this piece of software really is worth to them, be it through savings, additional income, time savings, it doesn’t matter so long as you track the value.
So how do you go about figuring out the ROI on software development project?

This is the difficult portion because it requires listening to the clients need carefully and scoping there need correctly, once you have done this, it should become fairly obvious what the client is trying to solve by having the software developed, this should then be a clear indication of the measure to be used on ROI. For example,a client of mine wished to have a system developed that automated the process of allowing shareholders in various properties to swap there owned weeks with each other. Before the client came to me they did this process manually, ie called there shareholders to find out if they were willing to exchange a week with a fellow shareholder that already gave an indication that they wanted to swap there week etc. This took a lot of time and for the administration fee that the client asked to do this, I suspect the profit was very little. Once we had developed the system and allowed the shareholders to interact with each other through the website instead of the web system, the ROI was very clear, why?

-We tracked each exchange in the system, each exchange has a monetary value associated to it.

-The clients telephone bill dropped significantly

-More swaps occur because of the ease at which shareholders can swap weeks, instead of having to go through a process of calling the company then waiting etc, this increase in sales is measurable

-Because the client offered the service electronically he could increase his administration fee.

All this information the client could get through there system thereby ensuring that he could very clearly see what his ROI was.
Conclusion

I believe without a doubt that if you truly want to complete a software development project successfully for a client, then you need to build a ROI tool into the software. Convince the client to do this, if you cant do that then build it free of charge, but make sure that you get your client to look at these figures. In the long term this will have a positive effect on your business and keeps your software development projects honest in terms of creativity and keeping the clients needs in mind constantly.

Please offer your comments and views on this topic, I am very sure that peoples opinions and views on this vary quite considerably, I am very willing to listen to other opinions in this regard.

In my next article on ROI and software, I will be describing more specifically how you can measure ROI on certain types of projects, in this case it will be how to measure ROI precisely in SMS campaigns.

Software Development Delhi – Techniques To Develop Software Products

The process of developing system software is known as Software Development. There are many stages that are part of software development which is also commonly known as Software Development Life Cycle. In short, you can call it System Development Life Cycle which is undertaken to develop a software product. In fact all the stages are important in order to create a reliable system software product for any industry. The roles of techies differ from each other to develop a software product. The fist stage is the feasibility study before developing a product. Its purpose is to find out whether system when developed will really support the requirements of the user. Then comes system analysis and design where a detailed study is done on the system that is to be developed and an analyst designs the product architecture based on which product will be developed.

Developers or Programmers are responsible for the coding part of the software product and Testers are to test the product when the software coding part is over. If there are defects or bugs in the system, the same is passed on to the software development team to sort out the problem. After coding and testing, the implementation process is commenced in order to implement the developed system software product to the industry for which it is developed. Another important phase is the maintenance, which is offered by the services company to undertake maintenance of the software product. The maintenance services are offered by the software development Delhi to the vendor for long term until and unless the product works for the vendor. This is actually a kind of contract between vendor and software company based on which the services are offered for years.

The rapid advancement in the field of Information Technology has also created demand for the latest technology on which the software products are developed for any industry. Many new technologies that have emerged in the software market and are considered to be very reliable. Due to this there is also demand of the software developers who are aware with latest and newest technologies. The new technologies have really boomed the software industry as very reliable products are created by new technologies by the developers.

India software industry has really helped many industries and companies around the globe to prosper in every respect. The software professionals are very skilled and have good experience to handle complex projects. They deliver productive results on time which makes them able to get more and more projects for their company from the vendor. Another reason is that software developers available here work at very reasonable cost and thus creates cost effective business for the outsourcing vendors. The outsourcing companies find the same project cost very expensive in their country and so outsource their task. This process helps to booms the Indian software development industry, brings revenue and employment for the Indian.
