Software Developer Salary

With the growth of the information technology industry, the demand for talented and skilled software developers has increased to a great extent. The software industry has achieved tremendous progress in the US and in Asian countries like India, creating many job opportunities. As a result, the junior and senior level salaries of these professionals continue to show a strong upward trend.

Pay Range

The salary of software developers largely depends on their years of experience, place of work, educational qualifications, and skills. Though the average salary is quite high as compared to several other professions, the entry-level pay might be low in some regions. The median salary is around USD 72,000 per year according to job market experts. An experienced programmer can earn around USD 60,000 per year. The pay of those having an experience of less than two years can be in the range of USD 35,000 to USD 45,000 per year. Those having an experience of three to five years can earn between USD 45,000 to USD 70,000 per year. Those who have been in the industry for eight to ten years can make between USD 65,000 to USD 90,000 per year. Whereas the senior professionals can earn in the range of USD 100,000 to USD 175,000 or even more.

Job Description

Software developers do the job of understanding and interpreting technical documents to create software applications. They also update the current tool and ensure that it is working efficiently. Senior developers have to take up the responsibility of monitoring, supervising, and checking the work of their juniors. They have to take care of the needs and requirements of the users while preparing the design. Conducting training sessions for the users, to learn the software are also a part of their duties. They are also responsible for creating test plans and technical specifications. They often work in teams or groups to complete the assigned tasks in time and within budget.

Requirements

In order to become a software developer, you need to have at least a bachelor’s degree in information technology or computer science from a reputed university. Securing admission in such a college would require you to score well in subjects like math, physics, and English in high school. A master’s degree in computer science can be the ideal way of entering this field, as this is what top employers generally look for. Initially, you might have to work as a trainee for three to six months before they take you on as a full-time employee. Knowledge of the latest software and programming languages, and having the relevant certifications can be an added advantage while looking for jobs in top firms.

Waterfall Model in Software Engineering

The waterfall model is probably the oldest and the best-known development models. The role of this model in software engineering is as important as its role in software testing. It forms the basic design, using which, over the years, a number of other software process models have been developed and implemented.

Waterfall Model and Software Engineering

The waterfall model is so named because it employs a ‘top-to-down’ approach similar to the water falling from a height under the influence of gravity. The following is a brief explanation of the different phases in the waterfall model.

Phases
For developing a software for small or large project, the waterfall model suggests that you employ the phases given below, in a step-by-step manner.

First and foremost, you need to completely analyze the problem definition and all the various project requirements. This phase is commonly referred to as ‘Requirement Analysis’. Once you have thoroughly and exhaustively identified and understood all the project requirements, they are to be properly documented, after which you move onto the next phase, which is known as ‘System Design’. This involves analyzing and specifying the project’s hardware and software requirements, and their inter-relation. In this phase, the entire software aspect of the project is broken down into different logical modules or blocks which are identified and systematically documented. ‘System Implementation’ is the next phase which involves writing the software code and actually implementing the programming ideas and algorithms which have been decided upon in the previous phase. Once the coding and implementation phase has been completed, the development process moves on to testing. This is precisely what happens in the next phase which is known as ‘System Testing’. The code that has been written is subjected to a series of tests, to detect and determine whether there are any bugs, errors or software failures. Once all the repair work, i.e. correcting and re-writing every piece of erroneous or flawed code is completed, you then move to the next and last phase which is the ‘System Deployment and Maintenance’. As the name suggests, the last phase is nothing but handing over the completed project to the client or customer, and subsequently performing maintenance activities, if needed, on a periodic basis.

Advantages and Disadvantages
Let us now examine the pros and cons of the waterfall model in software engineering as well as in software testing.

Pros
It is the simplest software development model and also the easiest process to implement.
This model is simple to understand and therefore is implemented at various project management levels, in a number of different fields.
It employs an orthodox, yet systematic and effective method of project development and delivery.
Cons
Since it is not an iterative model, it has its fair share of shortcomings and drawbacks.
Being a strictly sequential model, jumping back and forth between two or more phases is not possible. The next phase can be reached only after the previous one has been completed.
Bugs and errors in the code cannot be discovered until and unless the testing phase is reached. This can lead to a lot of wastage of time and other precious resources.
This process model is not suitable for projects wherein the project requirements are dynamic or constantly changing.
