Software Development Life Cycle – Introduction Model Stages and Advantages

What is the Software Development Life Cycle (SDLC)?

SDLC or Software Development Life Cycle is essentially the process or phases of a model or methodology, which software engineers and developers follow in developing an application or software. In simpler words, it is a process consisting of a series of planned activities for planning, creating, testing, deploying and maintenance of software.

SDLC is often referred as software development process, as it consists of all tasks, which needs to be followed while developing an application or software. SDLC is followed within IT development companies to develop, alter, replace or enhance the performance of the software. ISO/IEC 12207 is an international standard for SDLC, which ensures high quality of the newly developed software. It also helps IT development companies in improving the overall quality of their software development services.

What are the major SDLC Models, followed in the IT Industry?

There are various SDLS models, which are currently followed in the IT Industry. Often referred as ‘Software Development Process Models’, all the process models follow unique software development steps, ensuring 100% success of the development projects.

The major software development life cycle models are-

  • Waterfall Model
  • Iterative Model
  • Spiral Model
  • V-Model
  • Big Bang Model

Other related models are Rapid Application Development (RAD), Prototype and Agile Models.

The advantages of choosing an appropriate Software Development Life Cycle (SDLC)-

  • Increased Product Quality
  • Increased Development Speed
  • Improved Client Relations
  • Improved Tracking & Control
  • Decreased Project Risks

What are the different stages of SDLC?

Stage 1:

Planning and Requirement Analysis

This is the most important stage in the SDLC. This stage needs input from the customers, sales team, industry experts, a marketing team and their survey reports. After which, senior business managers and developers of a software development company plan the project approach and the development model.

Stage 2:

Designing

After the analysis of requirements and finalizing the Design Document Specification (DDS), the product architecture is designed by an expert team. This architecture has to stand upon various parameters such as budget, time, product robustness, risk assessment and design modularity, after which it is considered for the development.

Stage 3:

Development

The actual development of the software or application starts at this stage. The team of engineers and developers follow the coding guidelines set by the organization and use different tools for code generation. The programming code is generated as per the details documented in the DDS. The developers use different high level programming languages as per the requirement.

Stage 4:

Testing

In this stage, the final product goes through a pre-defined road of testing, where defects or bugs in the product are reported and then fixed by the developers. This stage ensures that the final product meets the highest quality standards, which are accepted worldwide.

Stage 5:

Deployment

At this stage, the final product is deployed at the client base. At times, the software is integrated with the client’s current application and database. All the deployment and integration works are done under the guidance of expert software engineers and developers.

Stage 6:

Maintenance & Support

Most of the reputed IT development companies also provide complete maintenance and technical support, post deployment of the final product at client base.

Real Estate Property Values – Ranked High

Rob Norquist, a real estate agent admits that Newport Beach is as active as it used to be, with some good record sales. He also agrees with the fact that a property, should never be considered deprecated, and as a seller, you should never give up and use the low end price. It is true that, during a certain period of time, depending on the real estate market, client’s desire, real estate auctions, there may be moments when a property’s price drops, but not forever.

Other cities such as, Huntington Beach, Costa Mesa, Irvine or Mission Viejo – are considered among other 25 cities as being the ones with the best real estate property values, with average values of $680,000 and more. The national average value in 2007 was $194,300.

However, some property values are based on subjective answers from residents living in a certain home, so the given numbers , and real estate evaluation may be hanging on a wishful thinking instead of a real appreciation . This is where real estate auctions come in picture, to inform potential clients about the property, and the investment possibilities, giving them a clear image of the real estate’s worth.

Even though some buildings such as Orange County properties , dropped their values in 2007, but they recovered extremely well after. So this is another reason why as a seller, you should never fear if you observe a temporally value drop, because it is normal from time to time.

For instance, about 81% owners, sellers, agents, trusted in 2007 that their estate property values were over $1 million, against 75% in 2006. So things are for the best and it would appear that most of estate agents have finally understood what this business is really about. It takes a lot of patience and ability to maintain your property’s value among top ones on real estate market.

But Norquist, trusts that many Newport Beach arguments are near the mark, sustaining that this city has survived the “housing slump” better than other locations. However, the unexpected surprise attacked more on sales, which he admits that they are on a falling edge right now, but there is still hope for better times.

Newport Beach is very well known for its highest-valued real estate properties in the U.S., being a perfect place for real estate business . It’s location and proximity to the water, and the beach front view increase it’s real estate value considerably. Auctions in this area are very interesting and those who are interested in real estate business domain should never miss them. You can learn a lot on such events.

Experienced real estate agents or even friends will surely advise you that as a buyer you are very likely to come across many real estate properties in foreclosure having perhaps no equity,being over priced . In such moments, lenders sometimes choose to accept a smaller amount than the initial.So you get in the negotiations process. As a hint, when you realize the over pricing phenomenon, you have to understand that this happens when the real estate agent , or seller is aware of the real estate property’s value, and he tries his luck in a raising price. So watch out! The negotiation can become a difficult process especially when reasonable terms are not agreed by both sides: owner and buyer. Negotiations can occur privately or in public, where real estate auctions come in the picture. Of course, a real estate auction is safer and more trustful than a private one. Private negotiations occur especially when the agent is a close friend or relative to buyer’s, and because of the friendly environment some details regarding even the real estate transaction may be skipped. So in situations like this be careful.

Even as a friend, for a real estate agent , money comes first, and friendship after. Of course, during such a negotiation, there can be all sort of problems, such as mortgage value, real estate market, all sort of official formalities, conflict of interests in a particular area etc. Moreover, time a very important issue when real estate auctions are involved. As a general rule, and as an advise for a potential buyer, negotiation process should not be extended on a long period of time, because, as I said before, in time, real estate properties drop their values, and the client’s interest together with it. In this case, not only does the buyer loose, but the real estate agency as well. Why?Because if a property’s value drops, the price must drop as well, if you ever want to sell it again. In this case the under priced phenomenon appears. This is why short sales are preferred. Many Realtors, and clients started using this strategy, because they faced the problem regarding their property’s value.So they decided the selling process should not take too long.

Another important issue refers to the well known “acceleration clause” , which is an official word met in any mortgage document, meaning that the lender, after the real estate property is sold, can demand the payment of the remaining balance for the loan. Realtors can provide more information about this contractual right. If this clause is good or bad for a real estate transaction, it is hard to say, because it has its advantages and disadvantages. Buying a real estate property which has already a mortgage loan represents a pretty raised risk. Why? Because first of all, if the mortgage loan was contracted for many years, depending on the interest’s rate, and marketplace evolution, you may come to pay the house’s price 3 times more. However, if you have experience in monitoring the market place, and find a right moment when every interest’s value drops, you could go for it. It’s kind of a gambling in this business, and Realtors, or individual real estate agents know it best.

Realtors and real estate agents are here on the real estate market, to help clients understand how they can value their houses, what should they look for when trying to sell or buy a house, how to negotiate, and how to win a real estate transaction. Some may say that buying or selling a real estate property is easy, but the fact is that pricing a house is a very difficult process. Many real estate agents, brokers, have suffered many defeats before their first good business, so do not expect their job to be an easy one.

Unfortunately, a concerning price and sales gains of these past years have determined in many cases quitting the real estate business. Many real estate agents who have seen the future preferred to do something else than real estate business. The credit market is also in a critical position, as many Realtors have observed. Mortgage values are also a result of real estate market position right now. Real estate investors have diminished their participation number to real estate auctions, as a sign they have seen it too.

Do You Need a Good Domain Name to Make Big Money?

Domain names may be somewhat important to the survival and the success of your website, but they will not automatically make you a success. They are actually a very small part of your success in the grand scheme of things, so do not buy into the idea that a good domain name will translate to big money. For one, there is only one way that the domain itself can earn anything without help from other areas of the business, and that way is by securing a name catchy enough and in high enough demand to coax a big offer from a company with deep pockets . But major companies have started to change the way that they do Internet business. They have become more practical, and have even been known to develop marketing platforms that will incorporate a new original domain name to get around having to pay you anything at all.

No, the best option, if you are an Internet entrepreneur, is to spend less time on what you are going to name your site, and more time on how you will conduct your business. There are many ways to do business, but in the online world, the key to success is mercifully simple. It's the content, stupid. How will you get a large audience if you do not have a quality piece of content to draw in the masses and get them talking to their friends and family. You need devoted visitors, who are willing to do the hard work for you. The way to get them is to be enthusiastic about what it is that you are about. And the only way to be enthusiast is to be passionate.

You can not fake passion. The reason you can not that that your audience has the passion, and they will be able to tell if you do not. So make sure you do not go into any business situation that you do not feel strongly about. It will be more difficult developing content – and more costing developing good content because you'll have to pay someone, who is passionate to spearhead your platform, and that will not come cheap if you want quality.

As you venture into the online world, you are going to hear a lot of business advice, both good and bad. The one thing you should know ahead of time is that throwing a lot of money after a domain name is a waste of time and resources. Instead of burning so many calories over that aspect of the business, focus your efforts on having a great site that people in your area of ‚Äč‚Äčinterest will want to visit. Something they will choose to go to bat for with the people around them.
