Software Development Rules
Posted by under: Non classé .
In the 20 years VORtech has been involved in scientific software engineering, we have seen many different codes and witnessed many different development processes. Some of the code was brilliant and a pleasure to work on. Some were less. Some development processes have been useful, others have not. Now the question arises. What change request do we need to implement in our software? It is important to be aware of the fact that it is impossible to know everything that is happening in the world of software development. It`s just too much. Each software reflects the organizational structure that created it. You add code to your application and increase the complexity of your system. So it`s good not to make unnecessary changes to your software. If a project is delayed, simply adding workers will likely have disastrous consequences. Looking at and checking the level of programming efficiency, software methodology, technical architecture, etc.
will almost always lead to better results. Or not, which probably means that Hofstadter`s law is also involved. « Before software can be reusable, it must first be usable » – Ralph Johnson You`ll notice that many of the above laws don`t apply directly to software, and that`s by design. The fact remains that software is designed to be used and interact with humans, so many of these laws are about humans rather than code. An example of Goodhart`s law in software development is lines of code. Lines of code are used to measure the size of a software product. However, when used as a target, the quality of the code decreases. User story is a term often used to talk about a small change in the software. We have imposed two constraints on ourselves: Software development is the ultimate discipline organized by paradigms and principles associated not only with coding practices and standards, but also with fundamental aspects of human psychology, with an emphasis on implementing a balanced software development process. Although we call them eponymous laws, as we might do for a scientific law, these are observations that have proven to be true quite reliably and their sarcastic nature makes them unforgettable – Murphy`s Law is a well-known example, but there are many. A related source of inefficiency is due to the antagonism and disconnect between developers and testers who operate in separate environments.
This is something that has been suggested in the section on layered construction. In the normal workplace, developers accuse testers of harassing them, and testers accuse developers of not giving them enough time. An example of a great source of waste is unnecessary reporting of errors in the tracking software. We found that the only types of bugs that really mattered fell into the following categories: « Hiring people to write code for sale is not the same as hiring people to design and build durable, usable and reliable software » – Larry Constantine This article is a summary of the practices observed over a 2-year period and the effectiveness of a software development team. Increased. The results have been greater customer satisfaction, increased activity and improved quality. Although a new atmosphere that has increased employee participation has been the result of organizational changes that have led to the development of agile software, the observations and interpretations are our own and do not reflect company policy. A version control tool, a continuous integration tool, and an issue tracking tool are now standard tools for all scientific software engineering. Yes, you can do without it, just as you can walk from Berlin to Paris. It just takes a little longer, right? No, seriously, bugs in scientific software can be very subtle and hard to find. If you can`t compare versions, if you don`t test frequently, and if you don`t record what`s going on, fixing bugs is hell.
The right tools are so readily available that there is no good reason not to use them. You should also pay attention to the documentation. The architecture, module, and components of your software must be mentioned in the documentation. Documentation is useful for seeing the high level of an image of your software, and it would be easier for new developers to work on it if they understand the full architecture of the software. They can make mistakes if they have no idea about the different parts or the complete architecture of the application. Moreover, modern development methods such as Agile and DevOps help to achieve this goal! Rapid iterations with regular user feedback enable data-driven decisions about what`s important. Practices such as trunk-based development with feature tagging (such as using LaunchDarkly) help software teams achieve this. One of the fundamental ideas in software development, especially in areas such as API design, can be expressed succinctly by the principle of robustness: in your programming journey, you have many options for a particular thing or problem. There you need to make a decision on the choice of the best option. Now the question is.
How do you make a decision about your software? How to prioritize things and what factors you need to consider to make a better decision. Be realistic about the expectations of adding new people to a software project. Adding people to a project is likely to increase speed at some point, but not always, and certainly not immediately. People and teams need time to settle into a work routine, and at some point, the work simply can`t be parallelized enough, so there`s no point in adding more people. Think carefully about what tasks a new person should do and what you expect when you add that person to a project.
