Software Development Life Cycle – Basic Steps Leading to A Strong Product

After realizing and experiencing the alluring advantages of outsourcing, more and more companies are getting inclined towards outsourcing software development projects to major offshore destinations. However, having an in-depth knowledge of software development life cycle becomes a priority task for not only the service provider software development company but also the client to keep a check on the project progress throughout the software development.

Software development is an intricate process that requires a lot of planning, implementation and testing. You can not develop perfect software with full functionality unless it passes all the tests and quality analysis. So, companies should keep a check on SDLC while experiencing software development outsourcing, a company No software is perfect and in full functionality unless it overcomes all the tests.

A software development company put special emphasis on SDLC to produce the most effective, functional and mission critical software that can help one’s business in a long run. The software development life cycle (SDLC) is a pre-set framework that is used by all software development companies for through understanding and developing effective information systems and software.

Though software development life cycle can have many versions and each version carries its own plus points and minus points, but all version have same steps or activities that are discussed below;.

Feasibility

First of all, the project is checked for its feasibility if it should get the go-ahead. If the project is to proceed, then a project plan is thought out together with the budget estimates for future stages of development.

Requirement Analysis and Design

After testing the feasibility of the project, system or software requirements are gathered. Business analysts perform a thorough study and analysis of the business needs of the organization and the market trends. Necessary changes are proposed. From interface design to data design, every program is discussed in this stage to keep the software of high level design.

This phase considers the overall structure of the software and defines the strategy for its development. That’s requirement analysis and design phase is believed to be the most critical part of software development life cycle. Any flaw in this phase may prove very expensive for further stages of life cycle. In simple words, this phase considers the logical system of the product.

Code generation and Implementation

This phase involves the code translation of the well-thought design. Desired programs are created using a conventional programming language and with the help of programming tools like Compilers, Interpreters, Debuggers. The code is generated using various high level programming languages like C, C++, Pascal, Java, etc.

Testing and Quality Assurance

Apart from requirement analysis, testing is another crucial stage of SDLC that decides the effectiveness and functionality of the product. This phase unravels the bugs and errors of the system. Initially the individual modules of programs are tested separately which is followed by testing of the system as a whole. The system testing includes the integration testing to check whether the interfaces between modules are working properly, Volume testing to ensure the capability of the system to work on an intended platform with the expected load of data, and acceptance testing to check whether the system does what the user needs.

Maintenance and Support

Software system maintenance is an inevitable need. It undergoes various changes once it is delivered to the client. Software development should be flexible enough to inculcate required changes with time and according to changing business needs. Inevitably the system will need maintenance. Software may undergo certain changes once it is delivered to the customer. There are many reasons for the change. Change could happen because of some unexpected input values into the system. In addition, the changes in the system could directly affect the software operations. Therefore, the software should be developed in order to accommodate changes that could happen during the post implementation period.

Each and every stage of SDLC carries its own importance and plays a key role in success of any software development project.

Computer Software Developers – Get the Right Software For Your Business

When you want some software developed for your business what is the first thing you do? Of course look around you for the best developers who can do the job for you. But I would say that is not what you should be doing, instead there is a much easier way to go about it which will save you lot of time and get your business up and running much earlier than you expected.

The technology behind software has developed so much that gone are the days you will have to find programmers or software specialist with whom you will have to sit around for month s day in and out charting and chalking out features to develop software instilling your plans and ideas into it. Now everything you require for your business comes in a platter without dropping a sweat. Well you may have ideas which no software developers or companies have thought of, I do not want to offend you, what I am getting at is that there are software solution for ninety percent of businesses that are being run today.

So when you are looking for computer software developers first ascertain whether you can get a system already developed just to install and run your business. If you have a good business mind but are not that computer savvy or up to date with developments in the field you need not necessarily know of all those new and new daily happenings in the software industry. You may even get taken for a ride by those who may sense this weak point of yours. They may just be selling you an already well developed system under the guise that they have personally developed the particular software system for your unique need and charge you a huge fee.

Fist thing you may do if you want help from computer software developers is to do a simple search on Google for all software systems that are available to your particular brand of business, get some in depth knowledge on what they can do to your business and then look for software developers that can provide you software systems that are customizable to your particular needs and ideas. Most developers can help you find the exact system you want with any special or particular features embedded or customized into the software as requested by you.

Selecting the software developers are not so easy these days because you find any number of them vying for your attention flouting the best quality system that money can buy. So selecting the best computer software developers is going to be a more of a dilemma than getting you the exact software for your needs. The best way to go about it would be to ask around and choose the ones your friends recommend or those who have enough experience in the field with proven results. I for one can recommend the developers stated below they are very affordable too but it is for you to make the final choice. Good luck.

UML Diagrams As A Tool For A Software Development Team

As we progress into the 21st century, our reliance on computer and information systems to facilitate business is greater than ever before. The global market is much too convoluted and relentless to be run on manpower and note-taking alone; software systems are crucial to a company when handling large amounts of data processing, customer transactions, or client databases. As such, their development and maintenance has become a key component in successful company operations.

To structure, plan, and control the development of these systems, a software development life cycle (SDLC) is developed and adhered to. Different methodologies have evolved to be applied for different purposes, based on technical, organizational, project and team needs, but generally all will use some combination of the following stages:

• Problem analyzing
• Market research
• Requirements analysis
• Design
• Implementation (coding)
• Testing
• Deployment
• Maintenance and bug fixing

How strictly this order is followed, and what level of planning and documentation is reached, will depend on the requirements of the business and capabilities of the software. A ‘waterfall’ approach to the SDLC would see each of these stages carried out in linear order, with detailed planning and risk assessment before coding is even begun. The ‘agile’ approach involves a lot less planning and documentation, and focuses more on coding and continuous re-testing, ideal for a smaller system, or one where new components are being added as an ongoing process.

Modeling software development using UML diagrams

While going through each stage of the SLDC, it can be useful, and necessary, to produce a visual model of that process. A diagram of this kind presents a graphical view of a software system’s structure, components and relationships, which allows the designer to organize and predict certain outcomes, as well as share system information with collaborators and clients.

The accepted standard used when modeling a system is known as Unified Modeling Language (UML), a generic set of notations that are used when creating UML diagrams. These notations can visually represent requirements, subsystems, logical and physical elements, and structural and behavioral patterns, that are especially relevant to systems built using an object-oriented style.

Using UML during the modeling process has a number of benefits – for one, the entire development team can share information and collaborate using common language, diagrams and software, something that’s not possible when using a more task-specific programming language. It allows team members to create system ‘blueprints’, creating diagrams that show system as a unified whole, but also allowing the option to break that system down into component parts or processes.

Currently on version 2.5, UML supports 14 different diagram techniques that are seen as industry standard. These diagrams are broadly divided into two categories; first are static structure diagrams, that describe the physical structure of a system. Then there are behavior diagrams, that depict behaviors and interactions of various system components. Here is a brief description what each diagram is and how it can be applied:

Static structure diagrams

Class diagrams – divides objects into ‘classes’, i.e. parts that share common attributes. Class defines the methods and variables of that object, and diagrams depict relationships and source code dependencies between them.

Component diagrams – displays system components (physical or logical), interfaces and ports, and the connections between them. Allows analysts to replace and system check individual parts rather than designing the process from scratch.

Composite structure diagrams – shows the internal structure of a specific class, the role each element plays in collaboration with others, and how this affects how the class interacts with outside elements.

Deployment diagrams – models the physical deployment of artefacts (software systems) on nodes (normally hardware, e.g. laptop, mobile phone). Execution environment nodes are a ‘node within a node’, a software computing resource that displays hardware characteristics.

Object diagrams – represent a system overview. Similar to a class diagram, the take a snap-show of a system structure at a particular moment in time.

Package diagrams – packages are formed when UML elements are grouped together – classes, objects, use cases, components or nodes. A package diagram shows this grouping, and dependencies between packages that make up a system. An example of use would be when modeling complex source code; packages are used to represent the different layers of code.

Profile diagrams – operates at the metamodel level to show stereotypes as classes, and profiles as packages. Allows the developer to create custom packages.

Behavior diagrams

Activity diagrams – can be said to resemble a flowchart, showing steps in a software process as a workflow. Binary choices from each step, yes/no, true/false, make this a useful medium to describe software and coding logic.

State machine diagrams – describes the current state of a machine, which values are acting upon it. It shows what actions the nodes of a software system take, dependent on explicit events.

Use case diagrams – shows an actual example of system usage. Helps define requirements for a software system, and can describes any possible form of interactions between users and that system.

Interaction diagrams

Communication diagrams – displays the interaction between objects in terms of a set of sequenced messages. It’s used to create a birds-eye view of the collaboration between several objects, for a common purpose within the system.

Interaction overview diagrams – like an activity diagram in that it shows a workflow through a system, but simplifies complex patterns by making each step a nest of interactions within the larger overview of an activity.

Sequence diagram – useful to describe object interactions in a specific time sequence. Can consist of parallel ‘life lines’ that depict an objects state at any given moment, and the sequence of time ordered events that affect that state. From a software perspective, developers use this diagram can show simple run-time scenarios.

Timing diagram – depicts the behaviors of a given set of objects through a certain period of time.

Software Development Life Cycle Process For Full Fledged Web Development Process

Software Development Life Cycle, commonly known as SDLC, is a predefined set of rules and methodologies opted by web development services company,used to develop, manage and maintain information structure, required to improve the quality of the software design and development process. A number of steps are followed to conceive the best available SDLC process in run. All the phases of the web development are equally important to the process and play the vital role while establishing a profitable development regime. The steps that are measured during the Software design and development are termed as follows:

Requirement Specification and Analysis:
The very primary phase during the execution of web development services called Software Requirements Specification or SRS offers a comprehensive elaboration of the functions and specifications need to be recognized during the software designing and development process. This very first and the foremost step allows to gather information about the overall requirements for the proposed software to be developed. The requirements analysis of the software is categorized further into several objectives to collect information about:

  • Resources required for the web development
  • Scope of the system
  • Purpose of the system
  • Limitations of the proposed system

A very mature and self-explanatory Software Requirements Specification Document is prepared in this stage to cover and enlist all the necessary guidelines to execute the web development services process.

System Design:
Once the requirement analysis phase is done, analysis outcomes are evaluated and scrutinized for the accuracy and efficiency measurement of the proposed web development system. The phase identifies the efficiency objectives taken during the requirement analysis process. The system design process describes the features and specifications in detail. The exhaustive elaboration of the several software design issues include:

  • Compact screen layouts
  • Defined business rules
  • Complete process diagrams of web development services process
  • Possible pseudo codes and other required documentation

Coding and System Testing Phase:
Next the phase cones for software coding where the application logic for the software functionalities and user interface are developed. All the coding are written in very strict accordance with the coding standards followed by the industry. The codes are developed in a way to save the system resources and optimize the system efficiency.

System Deployment:
In the very next phase of deployment at web development company,the final system sets live at the locations, it’s meant to be implemented at. The phase decides the shortcomings of the entire software installed and suggests recommendations to accommodate the changes that occurs during the post implementation period.

System Maintenance:
During the system maintenance phase, a number of things about the web application development are taken into the consideration including:

  • Changes required in the system
  • Correction of any sort
  • Some required additions
  • Computer platform adjustments
