Custom software development involves creating software which will serve as a tailor-made solution to the needs of that organization effectively. 5 Advantages of Custom Software Development 1. Personalized solution When you buy off-the-shelf software, it is never sure if they are going to work for your enterprise. Agile is a powerful tool for software development, not only providing benefits to the development team, but also providing a number of important business benefits to the client. Agile helps project teams deal with many of the most common project pitfalls (such as cost, schedule predictability and scope creep) in a more controlled manner.
V- model means Verification and Validation model. Just like the waterfall model, the V-Shaped life cycle is a sequential path of execution of processes. Each phase must be completed before the next phase begins. V-Model is one of the many software development models.
Software as a Service, also known as SaaS or on-demand software, is a way of delivering software applications to the end-user over the internet.SaaS can provide great advantages for most businesses, primarily in costs and flexibility. Advantages of Agile model: Customer satisfaction by rapid, continuous delivery of useful software. People and interactions are emphasized rather than process and tools. Customers, developers and testers constantly interact with each other. Working software is delivered frequently (weeks rather than months). Virtualization is developing new features each and every day, many of which promise to make software development faster, easier and less expensive.

No job is perfect. Every job has some advantages and disadvantages. If you are enjoying your job, that job is best for you. You should carefully choose a right career for you as it can make your life heaven or hell. If you have chosen for becoming a software developer, you must know the.
Find nikon lens serial number. Serial numbers can be found in different places on your lens. They do not have a standard location, but they are fairly easy to find. Just have a look at your Nikon lens and scan the surface. The serial number can be easily found because it is usually printed in white to help it stand out from the black lens. Jan 06, 2017 1. Nikon varies the locations of the lens serial number over the years. The early manual AIS lenses have their SN engraved and white filled at the front end of the lens or the front of the zoom ring. Latter lenses have their SN number shadowed engraved on the aperture ring.
Testing of the product is planned in parallel with a corresponding phase of development in V-model.
Diagram of V-model:
The various phases of the V-model are as follows:
Requirements like BRS and SRS begin the life cycle model just like the waterfall model. But, in this model before development is started, a system test plan is created. The test plan focuses on meeting the functionality specified in the requirements gathering.
Advantages Of Software Development
The high-level design (HLD) phase focuses on system architecture and design. It provide overview of solution, platform, system, product and service/process. An integration test plan is created in this phase as well in order to test the pieces of the software systems ability to work together.
The low-level design(LLD) phase is where the actual software components are designed. It defines the actual logic for each and every component of the system. Class diagram with all the methods and relation between classes comes under LLD. Component tests are created in this phase as well.
The implementation phase is, again, where all coding takes place. Once coding is complete, the path of execution continues up the right side of the V where the test plans developed earlier are now put to use.
Coding: This is at the bottom of the V-Shape model. Module design is converted into code by developers. Unit Testing is performed by the developers on the code written by them.

Advantages of V-model:
- Simple and easy to use.
- Testing activities like planning, test designing happens well before coding. This saves a lot of time. Hence higher chance of success over the waterfall model.
- Proactive defect tracking – that is defects are found at early stage.
- Avoids the downward flow of the defects.
- Works well for small projects where requirements are easily understood.
Disadvantages of V-model:
- Very rigid and least flexible.
- Software is developed during the implementation phase, so no early prototypes of the software are produced.
- If any changes happen in midway, then the test documents along with requirement documents has to be updated.
When to use the V-model:
- The V-shaped model should be used for small to medium sized projects where requirements are clearly defined and fixed.
- The V-Shaped model should be chosen when ample technical resources are available with needed technical expertise.
High confidence of customer is required for choosing the V-Shaped model approach. Since, no prototypes are produced, there is a very high risk involved in meeting customer expectations.
