Common Challenges with Software Development

Pinterest LinkedIn Tumblr

Modern development of truly successful and effective IT projects clearly implies the availability of effective technologies, modern design and development tools, highly qualified developers and sustainable funding. However, the participation of a large number of different specialists at all stages of analysis, design and development of a software system also contains a number of tangible pitfalls, the most important of which is communication between project participants. From this point of view, it is easier to contact a dedicated software development team and establish effective communication with the customer (the person authorized to make decisions on the product).

Documentation and communication problems

The actual problem of the process of developing software systems today is the problem of data visualization:

• Complete and accessible documentation of development processes;

• Descriptions of the tasks and capabilities of each participant;

• Visualization of intermediate solutions for demonstration to colleagues or the customer.

Development models and their approaches to team interaction

For an adequate analysis of data visualization problems in the process of developing software systems, we will consider the most well-known and actively used processes at present. One of these models can be considered a waterfall (or cascade) model. The main idea of ​​the model is quite simple: the whole process is divided into definite, clearly limited in meaning and activity, phases, which are performed in a strict sequence. The main positive aspect of using the waterfall model is the reduction in the number of long-lived errors.

Another well-known model is the development model – Rational Unified Process (RUP). The main difference of this model is the compulsory formation of precedents for using the software system to describe the requirements for the software system being developed. Each use case (case) is a description of a scenario of user interaction with the system that completely performs a specific user task. And the most effective way to document such scenarios is to graphically visualize use cases and the relationships between them using various case tools.

The considered models are quite effective, but they do not consider one of the most important problems of software development, namely the customer’s problem: the customer cannot clearly formulate all his requirements for the future system for various reasons. Therefore, a new process for creating programs was proposed – a spiral, dividing the process of developing software into two stages: design and analysis. The development of the system within the framework of this model is carried out according to the principle of repetition: the customer receives the next intermediate version of the system after passing through each turn of the spiral, which contains all the main stages of the system design. After that, the goals and characteristics of the project are clarified, its quality is determined, and work is planned for the next round.

Agile development

This development model can be categorized as a separate class. You can learn more about this model and its subspecies here managed IT services by 8allocate. In this article, we will provide a brief summary.

Features of Agile Methodologies:

• People-oriented – both customers and developers. In order to achieve success in development, you need the right team, which is often much more important than various processes and technologies;

• Maximum use of oral discussions. Discussions should be the main method of communication, both with the client and within the project team;

• Graphic visualization of requirements for software systems from the side of developers;

• Waiting for changes. The team will not follow only those requirements and a rigidly drawn up plan formed at the beginning of work, but will be ready for changes at any stage of development.
