There is a lot of different design and development models around. When the customer look for a new model, their understanding of software design, software development, software testing is what it can and should or should not be applied to.

The waterfall model for example, restricts design or each phase of work to a concrete stage of the software life cycle model yet prototyping models begin a new design (and therefore new following stages) on each prototype (throw away prototyping).

Having a blur-free understanding of how you perceive design is a powerful concept that is often inexplicable. Many programmers don’t necessarily know why they design something in such manner; conditioned over years of creating something the same way. They become informed about the concepts of object-oriented-design and then apply them to problems often with no adequacy or reason.

Knowing why you look at software design in that way, as you do, permits you to be more concentrated and do not make mistakes.

Ask yourself, what is acceptable software design? Maybe you think it’s a design that is simple or light weight. Or maybe it’s something that is variable. It’ll support a large amount of features in the future with little re-write needed. Maybe it is just something that is consistent, predictable and allows you to find a satisfactory solution to a problem systematically (software design patterns). All these ways are cool and only your choice is going to affect how you design a system. If you think a good design is a design based on simple elements, you must keep in mind that it is good for small projects. But on something larger you can miss a potentially better (albeit more complex) solution. If you always design with level of accommodation in mind then simple chances automatically come into contact with complex designs.

If you try to evade making changes, than you might automatically choose simpler designs. Without fail the client changes their mind, or the specifications change and you get into situation when your design is forced to deal with change.

If your project has specific time constraints (practically all projects are), then your are forced to look for a simpler design. You don’t have time to engineer a laborious solution.

You usually can’t change the time limitation, that you have, but partition this time|division this time into parts will help you prepare your design better. If you suddenly get more time to complete the project, when you have already finished it, leave your design for a while, and later on evaluate differently your choices. You may make a great number of decisions and arrive it at your design, but being away of those decisions can help you improve your next ones.

It is known, that, the mid-sized software companies is the most volatile of the companies of such type. Because they don’t have the liquid current assets to take giant investments forward in the industry and because they need to persistently take the lead of the smaller software companies that are competing for their niche in the marketplace.

So, mid-sized software companies trying to find ways to create new investments of capital, that they can’t take advantage for work in collaboration with their cost-reduction initiative at present.

Lowering training costs using custom e-learning content.

The first step to any well laid-out cost saving programme is to reduce the costs the organization currently incurs in order to get your head round benefit potential from sheer cost savings. Previously we will sketch what our predetermined budgeted cost item are…now we’re going to lower the costs associated with those categories by leveraging custom e-Learning content.

Take this plan of actions: A mid-sized software company that develops intranet portal systems now employs 3 trainers that are onsite with clients for end-user training 3 days per engagement and they each average nearly 50 engagements per year for a grand total of 150 days on the road per trainer or 450 days on the road collectively.

For these trainers, the onsite training program for the end-user customer may look something like the following: first day: Software introduction and primary functions; second day: functional use and administrative actions; third day: real-world functions and labs.

Lowering the costs: By leveraging custom e-Learning content, the company used in the above sequence of actions, can successfully reduce the onsite time required for each trainer, thereby reducing all costs associated with the training program across the board.

By using a professionally made, self-paced, custom e-Learning module to focus on the Software introduction and primary functions training that as a rule needs only one day – first day and then furnishing that learning module online to their final consumers at the time of purchase through an e-Learning Management System (LMS), this company could spare travel time for all 3 trainers by 1 day per engagement. This would reduce travel time for each trainer by 50 days per year, or 150 days collectively during the year.

In addition the ultimate recipients will already be experienced in the software package before the trainers ever set foot in the front door.
It will do you good to do this:

Calculate the costs associated with those 150 days of travel this tidy sum now is saved.
Enable the company’s trainers to perform more training engagements OR enable the company to cut down the number of in-house trainers it employs.

Reduce the costs associated with making and publishing the sections of the photocopy training manuals that deal with the Software introduction and primary functions training session that normally occurs in-person on Day 1 of the training engagement.

Reducing each trainers travel schedule by 1 day is good, but it isn’t good enough. Software companies employing this cost saving method should be in advance to increase their end-user customer’s experience. They need to make sure that their final consumers are learning what they need to know to guarantee, that time isn’t being wasted covering the same topics when the trainer visits the customer site in-person.
To do this, the software company needs to look at how they plan to deliver the online training to their ultimate recipients.

They will want to make sure that the ultimate recipients can chart and control the online training portion of their sessions, whether it is self-paced custom e-Learning content or real-time online trainer/student collaboration. Selecting this delivery platform can be not easy but it should contain the following basic functions:

1. Student Knowledge Assessments
2. Student Success and Progress Tracking
3. Real-Time Interactivity
4. Self-Paced Learning Delivery

By selecting a delivery platform that addresses all four of these sides of end-user customer training, the mid-sized software company can not only reduce their own costs but enhance their client/vendor relationship by delivering more than what is in usual practice expected or experienced in today’s software market. What’s the bottom line? The customer is content with their user’s performance and the value they received from the software company.

Outsourcing software development work is a hit these days. Many companies and individuals rather go for software development outsourcing instead of doing it in-house. Software development work isn’t a task as it includes a lot of planning, strategizing and testing. No software is without any faults and in full functionality except it overcomes all the tests. This is the reason why many companies deal with software development outsourcing also keep a check on its testing services.

Any company supporting software development outsourcing usually follow a software development life cycle, known as SDLC. The software development life cycle is an established framework preferentially used for understanding and developing information systems and software successfully. Nowadays, businesses can easily obtain software in various ways that is from simply buying it off the shelf to creation a made-to-order system to the business’ needs.

This software development life cycle has got many variations and each version carries its own merits and minuses and avails and troubles . Software developer can without efforts understand how each of these methods affects risk. Many software developers also call Software development life cycle as classic life cycle model or linear sequential model or waterfall method. Each and every software developer has got its own name and definition.

All the software development life cycle contains following activities:

At first, system/information engineering and modeling – Software are always contain a large system, and work usually starts by setting up the requirements for all system elements. Next step is to place some subset of these requirements to software.

Software requirements analysis – this stage is also known as practicability study . In this main phase, the development team mainly visits the customer and studies their system.

Systems analysis and design. This is the third stage in which, the software’s overall structure and its nuances are stipulated . Being in terms of the client/server technology, it needs in a number of tiers for the package architecture, the database design, and the data structure design.

Code generation is performed in a detailed manner, and can be easily complete without much difficulty. Programming tools used to generate the code are compilers, interpreters and debuggers.

Testing is the phase, which is needed to check the quality and its functionality. Various testing methodologies are available to discover the bugs.

Maintenance. Software surely changes frequently once it is delivered to the customer/client.

All of above-listed has got its own importance and plays a vital role in any software development work. For more information on software development just click business software development, or for adding information about software development company, visit our web software development site.

There are three principal types of software, with there own subsections:

1. Commercial software, acquired with a licence for one or more computers. This usually integrate some form of support and regular updates to patch errors etc. Sometimes a new version of the software is offered at a special price as “update”. This type of software is usually very expensive and is often made to cover particular industrial aims. The big exception is the various sets of “office” software, which are made for use in the commercial environment, but can easily be used for various tasks at home.

The most common use in this category is, of course, text redaction. Most of the other traditional “office” applications, such as calculations and data bases are only of limited use in the domestic environment, although they will be used in some cases, properly now that the more computer-literate generation is growing.
2. Made easier; or “lite” versions of the commercial software. These are meant for small businesses and enterprises that do not need the complete capabilities of, for example, a 3-D modelling system, but must be able to view such documentation and prepare compatible drawings.

Again, the “office” environment was for many a long day not represented in this sector, but has now started to be available. These will also come with a single or multiple, but limited licence and now mostly be registered with the producer.
3. Free or “open source” software. This is created for general distribution and has no special restrictions as to use, except that it may not be transformed in any way. Naturally, such software has its limitations, but may serve very allowably for many purposes. Practically all types of software are to be found in this category. One notable application distributes the software to read its documents freely, but charges for the software to produce the documents. This policy is probably the motor behind its ride to a position as industry standard, since you can always be certain that he receiver can decipher whatever is sent, without long discussions about compatibility and versions.

It is evident, there can be no piracy of products that fall into the third category, except for modification of the code or reuse of the code for other purposes. Linux community has efficiently used this model to provide a number of successful and popular packages.

Taking all things into consideration, it can be said that now, free or “open source” software plays a chief role in building the software industry and it has not problem of piracy, because does not limit the use of software.

Open-source software (OSS) is computer software whose easy-readable source code is widely available perhaps under copyright. People have the right to alter the software and redistribute it, whether modified or not. Development is often a common, combined process. It is declared that open source software may save buyers $60 billion per year.

Let’s look fixedly at some of the distribution criteria. Any redistribution must contain the source code. Reasonable reproduction disbursements are allowed, but the software is usually downloaded free per the Internet. Modifications must be distributed under the same time-frame as the original product. Discrimination against individuals, groups, or fields of application is inadmissible. The license may not specify use of any technology.

Open-source software ensues from the free software movement that started in 1983. The word free can mean no cost or at liberty. To shun this uncertainty, people started using the term open-source software. Netscape released its Internet browser source code as open source. Yet the company was sold for several billion dollars in spite of the fact, that users didn’t have to pay even to download the browser.

Here are several rules of open-source software development. Users should be treated as co-developers. They can add important features to the software. The more users means the more testing environments. Microsoft has partly accepted this principle by making beta versions of software such as Windows 7 available to millions of people. The software should be released at the right time to get more people implicated as soon as possible. The fixes should be added quickly rather than towards the end of the project. The software should be out in at least two versions, one with more features and the other more stable.

Does open-source software work? Let’s scrutinize some good results. Linux is a widely used operating system, inherently a variant of the decades-old Unix operating system. Many organizations have adopted Linux replacing Microsoft Windows based systems. Firefox is the second most widely used Internet browser.

Open-source software doesn’t always come in second. For more than a dozen years Apache has been the most widely used Internet web server. It is well connected with other open-source software such as Linux but also works with Microsoft Windows. If you want the latest Apache updates and fixes (and presumably most web hosting companies do) you will get them first for Linux and only later for Microsoft Windows.

How do people earn money when the open-source software is given away gratuitously? There are several answers. Some people and companies obtain money from consulting and training fees. Another possibility is charging for advanced product versions.

Announced in the title, generation gap is the conflict between Open Source Software and Proprietary Software. Proprietary software ran the show in software industry. But now it is stretching itself to the limits to overpower the crisis it is facing largely from the open source software market. So, what’s the odds?

Proprietary software

There are no two ways about it that for the primary business model for closed source software, the supplier determines certain constraints and limits on admittance to the source code and also on what can be done with the software. It may be noted that copying and redistributing of software can be done easily. FOSS suppliers do this as part of their policy. Taking this as a danger to their gain making motive, proprietary software firms sometimes produce an illusion of artificial shortage of the product. This is like black marketers who produce an artificial scarcity of food products during a crisis. In this case of proprietary software the end-user is not actually acquiring the software, but only get a right to use the software. Therefore it can be clearly evidenced that the source code of closed source software is well thought-out trade secret by the owner.

FOSS (Free and Open Source Software).

FOSS does not limit the use of software as done by closed source software. The purveyors of FOSS generate receipts through support services. An example for such a company is Canonical Ltd, which gives its software at no charge but charges for support services. The source code is given along with the pre-compiled binary software for convenience of the user. As a result, the source code can be freely modified. However, there can be some license-based limitations on re-distributing the software. Generally, software can be modified and re-distributed for free, as long as credit is given to the original producer of the software. FOSS may also be funded through charitable contributions. Linux community has effectively used this model to provide a number of successful and popular packages. Software like OpenOffice and MySQL has been immensely in the open market and has forced Microsoft to reduce its prices and provide error-free operating systems and solutions.

Windows 7 was distributed at a lower price remembering the competition from FOSS. Windows Vista was not a success, largely due to the fact that its memory hungry interfaces and applications were not popular among the users. To keep up the criticism faced by Windows Vista, Windows 7 was released at a lower price and with better features. The credit for this change can be attributed to the overwhelming popularity of FOSS.

Taking all things into consideration, it can be said that in the coming years, FOSS will play a main role in shaping the software industry and by giving the user the final say. The positive side of this competition is that Proprietary software will improve in quality and will be forced to fix limits on pricing. This is a good signal for the software sector globally.
