소프트웨어 설계

모바일폰(안드로이드 또는 IOS)이나 PC(윈도우, 리눅스)의 설정이나 기기 데이터 시각화에서 가장 중요한 부분은 USB, WIFI, BLE, 이더넷 또는 다른 프로토콜을 통해 기기와 통신하는 프로그램입니다.

프로젝트 프로세스

Alpha Beta Gamma

Requirements design

As the first step our team makes technical requirements of the software, it describes all technologies (database, communication protocols, Frameworks, GUI, architecture of each module) and logic of the work

Diagram design

At this stage, we do architecture design based on the requirements. It usually includes: a software block diagram, a workflow diagram (describe deep logic of the work), and a UML/API diagram(describe all files and code classes/modules)

Start code development

In this stage, we divide the scope of the work based on the UML/API into small sprints (usually 2 weeks each) and make planing with the delivery of each part. Each week make small delivery of the code based on the planning

Code review and testing

If the project has enough code size and budget (we have rules), a responsible engineer does a code review. After that’s QA engineer tests all the code files rather manually or by writing the tests.. For the current steps, we use the standard GIT mechanism with merge request and management schema from Jira

Code delivery

When some parts of the code is done and it’s agreed with the customer - we deliver (release) the software. Use usually for this GIT standard mechanism of the delivery/release code and GIT tags. The delivery includes full development of the current stage, code review, full regression testing and a demo project that shows how the current part of the code works

Finalizing code development

It’s the last stage of the development, on this stage we finish the development, code review and testing of the final code. we make sure that we fit the technical requirements and expectations with the customer. Especially, all our software are based on the device control(BLE, USB, CAN, WIFI, etc) and in this case, we need to make sure all works well and final testing was done with the last device version

Support and bug fixing

Each project has a support stage and bug fixing because after a final release, will need some improvements. We usually agree with the customer on a period of support. It could be how a few months and a few years (if a complicated project)
