JazzTeam is a service company with streamlined processes and an established culture focused on long-term customer cooperation. We have been supplying high-tech IT solutions to the European and US markets since 2011, and have successfully completed over 100 projects. Our clients are leaders in the European telecom market, e-commerce and marketing solutions providers, and innovative companies which create the most complex products in the sectors of science and Internet of Things (IoT). Among others, we work with Silicon Valley companies and residents of the Skolkovo Innovation Center.
Our service and project management standards are based on Agile software development methodologies, while the company’s technical expertise is based on Java technology. This approach was consciously chosen from the moment the company was founded, and determines the way we work today. The approaches we have been following for over 10 years are reflected in our “Agile Java Development” slogan. Each part of this slogan demonstrates the values and working principles of our company.
Before creating JazzTeam, our CEO, Dzmitry Harachka, was professionally engaged in Java development on international projects for many years. After gaining extensive experience as a developer, architect, and Open Source projects committer and consultant, he became convinced that Java technology is one of the most universal and effective solutions for providing IT services.
Focusing on Java allowed our company to occupy its niche and gain popularity on the market. By focusing on one technology, we have been able to create an environment of real expertise in the company. Our accumulated experience allows us to analyze product architecture more deeply, share best practices between different projects, and effectively solve technological problems, thereby enabling us to do our job more professionally.
This approach is reflected in our values: we believe it is better to do one thing perfectly than a lot of things at an average level.
JazzTeam quickly reached a stable flow of orders and accumulated a pool of regular customers who were completely satisfied with our service level and highly appreciated our work. We have continued to maintain strong partner relationships with several of them over many years. The effectiveness of our chosen approaches and the high quality of our services were also noted by Clutch, a leading ratings and reviews platform in the IT industry. According to its 2020 report, JazzTeam was among the leading companies in the “Development” category in our country.
Agile software development is very popular on the IT services market today. Customers increasingly prefer to take an active part in the project, want to constantly track progress and influence it, and are interested in the prompt introduction of new functionalities and quick product releases. The classic waterfall model does not always allow a vendor to meet the customers’ actual needs. The lengthy requirements formalization stage and the strict sequence of development stages often prevent a team from focusing on the implementation of the most important business functions. With the waterfall model, a product can only be used after the entire scope of work initially fixed in the requirements specification is completed. This type of cooperation does not allow the checking of the effectiveness of the developed solution in the early stages of the project, which can be crucial for the customer. Also, with this type of cooperation, the customer cannot be fully involved in the development process and can only influence the final result during the requirements collection stage.
Using Agile project management allows us to respond to the actual requests and business challenges of our customers. Commitment to Agile philosophy and practices provides several advantages to a vendor company.
Effectiveness. Agile methodologies presuppose a quick start of work and provide conditions for testing hypotheses at the MVP stage. Rapid response of the team to changes in project requirements and priorities provides an opportunity to create the most relevant and important functionality to contribute to the customer’s business development.
Transparent of processes. Agile culture increases the effectiveness of cooperation through open discussion of situations on the project with the customer. A short feedback cycle and regular communications (standups, demos, and retrospectives) adopted as a rule in Agile processes contribute to achieving a common vision shared by all project participants. The development team and the customer get a clear picture of the project’s actual status, ongoing events, the current status of tasks, and the progress made so far. This continuous direct communication, both within the team and with the customer, accelerates the process of making important decisions and prevents unexpected risks, ensures continuous knowledge sharing, and increases the efficiency of interaction between team members.
Performance. The iterative approach focuses on obtaining concrete demonstrable results every 1-2 weeks. The main progress indicator for a team working according to Agile methodologies is frequent and regular deliveries of new product versions, which brings real benefits to the customer during the development process. Due to Agile processes and effective management, the team maintains high performance levels throughout the project.
Flexible cooperation conditions. Agile practices presuppose flexible project parameters. The customer can effectively reconsider the budget and decide which functionality to invest in now, and which is still worth refusing. The same applies to the use of best practices. For example, in response to product instability, the team focuses on test automation. It is also possible to terminate the development at any moment (according to the contract terms), for example, if the customer understands that the created functionality is sufficient to achieve the set goal.
JazzTeam applies Agile methodologies at three levels:
Below, we will tell you more about how the above practices and approaches affect our work and what benefits they bring to our customers.
When building the JazzTeam philosophy and processes, our CEO, Dzmitry Harachka, was inspired by the postulates and principles of the Agile Manifesto.
The Agile philosophy and approach are natural to us, so the above principles are also reflected in our cultural values, priorities, and approaches to project management.
When we start working on a project, we are always proactive and offer our customers technologies and processes that will improve their business. In our company, customer relations are not limited to the ‘contractor-customer’ concept. During our cooperation, we often consult business owners and representatives to immerse them in complex concepts and practices of IT processes and infrastructure, and explain to them how small investments in technical debt handling here and now will be returned in the form of product stability and scalability in the future.
A high level of engineering and constant application of the best approaches to development and testing (CI/CD, Unit Testing, and Data Driven Testing) make our products more sustainable and flexible. Components designed by our engineers have a low coupling degree, which allows us to build application architectural layers clearly separable from each other. As a result of our engineering approach, we professionally refactor complex, hard-to-maintain code and ensure a high level of reuse of developed components. All this allows us to reduce the cost of product support and involvement of new specialists on a project.
Agile culture, application of best development practices, and constant work with technical debts are the driving force of continuous progress on a project. The product's initially well-designed architecture and loose coupling of code components not only make it easy to change the product, but also stimulate its continuous improvement and development.
Only a well-coordinated and motivated team can create valuable, complex, and high-tech software systems. We believe that a combination of keen interest in what we do and strong team spirit helps us to create unique and useful products. Therefore, we pay great attention to forming project teams and set high requirements for talent acquisition. Our teams function as integrated groups, so one of the most important tasks of a JazzTeam recruiter is to select a new team member who can seamlessly blend into the processes of a particular project and who possesses the personal qualities we look for in a colleague. In addition to professionalism and maturity, the talent and desire for self-development, hard work, sincerity, and responsibility of candidates are also very important to us.
We select technical specialists based on the standards created in the company. Before starting work on any of the company's projects, a developer must have Unit tests writing experience, understand all stages of the CI/CD process, independently evaluate and decompose tasks, and timely escalate arising issues to the project manager to prevent risks affecting the project (follow the Red Flag concept).
We provide all the conditions necessary for our employees to comfortably work, develop, and grow professionally. For junior specialists, we create and apply our own effective training and adaptation programs, which allow us to prepare an employee for full-scale work on a real project.
Working based on Agile software development methodologies allows us to immediately integrate continuous integration and delivery into the project workflow. The IT solutions developed by our teams initially have a modular architecture and loose coupling of components, which allows us to ensure the effective implementation of new product features. This means that fast deliveries are already guaranteed in the early development stages. For our customers, this is an excellent opportunity to concentrate on important business goals and promptly receive new software versions for testing by targeted groups. In order to create the most important and in-demand functionalities (MVP), our team is constantly in sync with the Product Owners on your side, including your sales and marketing departments.
Each member of our project teams is responsible for the overall result and constantly strives to improve it, proactively works on tasks, and initiates evolution of project processes. An important component of our culture is the passion for professional growth and the expansion of competencies with new tools and approaches. Our specialists continuously develop and learn new technological tools, as well as methods and approaches to development and management. For example, on one project it became necessary to switch to working in a cross-functional team (Feature Teams) created to solve the specific business tasks of the customer. JazzTeam specialists successfully completed the task, and it was an example for other customer teams to switch to this model of organizing the development process.
We have developed our very own performance criteria: the result obtained upon completion of a task is always concrete, demonstrable, and predictable. JazzTeam has adopted values such as decomposition of tasks, realism in estimation, and objectivity in accepting the result at the level of culture. Our professional approach to work allows us to steadily make high-quality software deliveries, achieve goals within the stated deadlines, and maintain the team's productivity at a high level throughout the project.
We are focused on the analysis of work done and continuous improvement of processes, so we regularly organize retrospectives — special Scrum events in which we discuss problems and ideas that arose on the project during the previous sprint. Their main result is a clear plan for the next iteration for solving various problems faced by the team. Timely retrospectives reduce the organizational and technological debt and improve psychological climate and team productivity. All this contributes to the effectiveness of the product development process.
On one project, JazzTeam specialists conducted 3 quarterly retrospectives with the customer in less than a year, resulting in significantly increased productivity, improved communication processes, and reduced stress in the team. These results were achieved despite the fact that our specialists acted as independent third-party experts and consultants on the project, which had been in existence for more than 10 years.
Scrum is an Agile software development methodology with its own approaches to organizing project processes (sprints), tools (backlog, Scrum board), and roles within project teams (Product Owner, Scrum Master). According to Scrum, project work is broken down into short iterations, or sprints (1 to 4 weeks), which include every stage of development: from planning and analysis to implementation and release.
Scrum processes help to establish regular deliveries of new product versions, and ensure the transparency of the team’s work for the customer through daily standups and demonstrations of the functionality created during the iteration. Achievements and problems which arise in each iteration are analyzed during retrospectives.
In addition to these benefits, Scrum is an excellent organizational framework for company operations, which has been proven over our 10-years of using it. Scrum methodology is the basis of work for all JazzTeam business units, including the ones not related to software development (marketing, accounting, and administration). Our company has created a Scrum Rules document, which summarizes and formalizes the rules of the application of Scrum methodology tools (Scrum board) and events (standups, retrospectives). Having studied this guide, JazzTeam specialists quickly learn how to work with Agile methodologies and apply these practices in their daily work. Each JazzTeam employee maintains their tasks, estimates risks in advance, achieves specific results by the end of the sprint, and analyzes their effectiveness in retrospectives. All this contributes to the efficiency of our processes.
Over our many years of working according to Agile principles, we have accumulated extensive experience in building processes based on Agile methodologies. We will be happy to share our expertise with you to help you implement Agile practices in your projects. Our company also provides consulting services. Very often they are the beginning of our cooperation with customers within our other services, such as test automation or project management.
In addition, our CEO, Dzmitry Harachka, who has more than 10 years of experience implementing Agile methodologies in various companies, consults founders, owners, top managers, and shareholders of companies on the effective implementation and use of Agile and Scrum on software development projects. You can find more details about this service at zmicer.consulting.
Our engineers apply the best practices of eXtreme Programming. Constant code review, collective code ownership, pair programming, and the unified code style are the approaches which help our teams to create products with a well-defined and logical architecture and easy-to-read and extensible code. Definition of Done, memory maps, and brainstorming sessions are the necessary and natural tools for our specialists to improve their performances.
We implement continuous integration and delivery (CI/CD) at the early stages of a product life cycle and use the Test Driven Development approach, which ensures frequent deliveries of new functionalities with high quality. Our engineers always adhere to the principle of realism and independently analyze and evaluate their tasks, which allows them to achieve the necessary results in time without stress or overtime work. Thanks to this approach, we are able to achieve high levels of productivity and establish a healthy psychological climate within the team.
By applying eXtreme Programming principles, we significantly reduce the cost of development, testing, and further support of the systems we create. Due to constant communication with customers, we clearly understand their priorities and provide exactly the product they want to get in a timely manner. We ensure effective teamwork, where each project participant is actively involved in the IT solution creation processes and is responsible not only for their own tasks, but also for the overall result.
The Java programming language has been popular in the IT community for over 20 years, and remains very popular to this day. Java is a leading technology that occupies the top lines in the popularity rankings on the IT services market. So, for 15 years this technology has been one of the top three leading programming languages according to the TIOBE community.
SlashData, a leading developer economics analysis company, has determined that more than ⅓ of the world’s total number of developers choose Java. This technology is used for creating products for cloud infrastructure (Amazon Web Services, Google Web Services, Oracle Cloud), machine learning, neural networks, for working with Big Data and applied science programs, and in the field of Internet of Things (IoT). It is also an excellent tool for solving complex research problems.
Java is a key area of JazzTeam’s expertise. However, this doesn’t mean that we use this technology to the point where we neglect others which may be a better fit for a particular project. It is a conscious choice which has allowed us to accumulate deep knowledge in software development and provide professional engineering services based on this knowledge.
Being focused solely on the chosen stack, along with our vast experience in Java server side applications development allows us to apply the best practices of this programming language to various aspects of our projects. By adhering to engineering standards and approaches, we have gained extensive experience in architecture building and software design and constantly apply the best practices from the world of Java to other programming languages.
Our company developed a methodology for retaining experience and reusing it between projects. If any of our teams has questions or difficulties, the entire technological expertise of the company accumulated over many years of work can be used to solve them. We also created an effective experience transfer system with the help of reference projects, which transfer best development practices to engineers and help specialists effectively immerse themselves into new projects.
JazzTeam created its own training program for Java engineers. The unified IT education system allows us to continuously enrich employees with new experiences and effectively transform education methods and plan for the future. The program is constantly updated to keep up-to-date with the latest trends and standards. As a result, we can guarantee that the knowledge of our technical specialists meets the current requirements and demands of our customers.
1. We follow the best engineering traditions and practices:
2. The approaches we use on all our projects:
3. We are happy to take on complex R&D tasks. For example:
We are focused on creating high-tech IT solutions for the effective achievement of all our customers’ business goals, and are interested in active participation on their projects. The concept of ‘Development’ in our slogan is not only limited to product development and code writing. We offer a comprehensive service, including business analysis, planning, process structuring, design, testing, and deployment.
JazzTeam has established a value-based engineering approach to creating IT solutions. We always start the development process with the product architecture design and make various UML diagrams (deployment, classes, sequences, components, etc.), which are necessary to achieve a common vision of the concept and functionality of the product by the team and the customer.
Our specialists use engineering approaches and practices in their work. On all of our projects, we first of all implement continuous integration and delivery (CI/CD) or significantly improve these processes if necessary. Timely implementation of CI/CD ensures predictability and stability of product function and reduces the cost of its further support. With continuous integration and delivery set up, developer-written parts of code are immediately integrated into the system and must pass daily testing (Unit, integration, and regression testing), which makes it possible to arrange regular product deliveries with complete confidence in their high quality.
Implementation of CI/CD includes the continuous application of best development practices by engineers: it establishes a single coding style in the team, as well as systematic creation of Unit tests. Introducing CI/CD and the best development practices allows us to improve the technological side of the product and contribute to the optimization and improvement of processes on customer projects.
When we find bottlenecks in the product, we apply automated tests to that part of the code. The autotests we create are integrated into the CI/CD processes right from the start and become immediately useful. Due to the implementation of autotests, the Product Owner can make sure that the key functions of the system work properly at any time, which allows them to avoid huge expenses on manual quality control and lengthy product stabilization. If there is a need to test a large amount of input data, we use the Data Driven Testing approach.
We constantly consult business owners on product development and offer ideas to improve the project’s processes or technological aspects. JazzTeam managers are facilitators of the service. Regardless of the size of the team or the task that needs to be done, our services always include the participation of a manager on the project. This means facilitating communications, creating documentation, and setting up processes on our part. Our managers provide a high level of process management on a project, introduce necessary task tracking and test management tools, and apply best product development management practices.
We are always ready to adjust to the customer’s needs and offer the optimum cooperation model:
In project management, we rely on Agile methodology: we use short iterations and seek constant feedback from the customer. This approach allows our customers to receive and evaluate the first significant results of the work in just 2 weeks after the start of cooperation, and to make sure of the transparency of our processes.
By choosing JazzTeam, you choose a company with a clear focus and established culture. We have been following the principles reflected in our slogan for more than ten years. Agile philosophy, Java technology, and Development services are our foundation for solving technologically complex tasks and building productive relationships with customers.
We are always glad to interact with you!
