Why can we humans complete major building or engineering projects with relative ease yet struggle to deliver software projects that are bug-free and on schedule is a common question. Below are 5 reasons why software designing is very difficult.
1. The software industry is quite new and young
For thousands of years, humans have been building houses, roads, and bridges. We have no clue how many houses or bridges fell down in the early days as people learned how to build these things correctly.
The software industry, on the other hand, lacks the variety of pre-built components found in other industries. Software systems are formed primarily via the discovery, innovation, and development of new components, resulting in each new system being a unique project established from the ground up. This reason leads us to the next point.
2. Each line of code has the potential to fail
Because all new projects are developed from the ground up, every line of code is fresh and should be thoroughly tested. In the actual world, however, this is completely unworkable.
There will be hundreds, if not thousands, of possible inputs, outputs, states, or dependencies to deal with in each line of code. Other lines of code or external circumstances can influence or be influenced by it. Even if every test case for a piece of code could be documented, there was no guarantee that an error wouldn’t occur due to some unknown circumstance.
3. Lack user detailed inputs
This reason might be due to many different following factors:
- Management’s promotion of the technology and the lack of buy-in from business users.
- Users are distracted by tasks that are “more important.”
- The user community and the IT team have a strained relationship.
The initiative is bound to fail without the involvement and feedback of a user representative. This individual should be a subject domain specialist with decision-making power and a commitment to project deadlines.
4. Users are clueless about what they want until they see it
Even with excellent user input, no amount of study of user needs can change the fact that consumers only believe they know what they want. In reality, it isn’t until people see something and use it that they begin to comprehend what they require. This is especially true when the software is being built for a novel idea or procedure.
One of the most difficult challenges that all software developers face is changing requirements during the development phase. It is possible, but don’t expect it to be easy. Please don’t believe that additional needs can be fulfilled without compromising the timeframe or budget unless there is a matching budget or timeline.
5. External variables have an impact on all software
Although the software is “mindware” and so defies physical laws, it must typically adhere to extrinsic restrictions such as hardware, software integration, government requirements, legacy data formats, performance criteria, scalability, and so on.
It’s nearly hard to comprehend and cater to all of these external influences. Even a seemingly basic need like supporting different browsers raises the difficulty of both developing and testing software considerably. When you throw in the necessity to support numerous versions of each browser, the complexity and difficulty skyrockets.
Software is similar to an iceberg in that 90% of it is hidden. The application’s main complexity is hidden under the surface and is not visible to the user. All you need is support from an experienced and dedicated software company. vITcake is here to make it easy for you.
