2. Define the skills your remote embedded team needs to have

The technological toolkit, or tech stack, that an embedded software engineer utilizes can differ significantly based on several factors. These primarily include the intricacy of the product being developed and the specific requirements set for the project. Nonetheless, certain skills and experiences remain universally necessary across all embedded projects.

Experience with General-Purpose Operating Systems (GPOS) and Real-Time Operating Systems (RTOS) stands out among these critical skills. These operating systems form the backbone of most embedded projects, with the GPOS providing a flexible and versatile platform for software development and the RTOS ensuring the timely and accurate execution of tasks, which is a critical factor in embedded systems.

Another essential skill for an embedded engineer is proficiency in programming languages, notably C and C++. These languages are often the foundation of embedded development due to their efficiency, direct access to hardware resources, and control over system components. Project specifications sometimes require knowledge of other programming languages such as Java, .NET, and Python.

An embedded engineer's role goes beyond programming language proficiency. These specialists must also demonstrate a solid grasp of theoretical and abstract concepts. They include algorithms, design patterns, and data structures, which organize and store information. Understanding control systems is crucial, as these often form the core of the embedded systems, responsible for controlling the interaction between various components.

A qualified embedded developer should also be familiar with networking technologies. It includes Ethernet, the standard for wired networks, and TCP/IP, the suite of communication protocols used on the Internet. This knowledge is necessary to facilitate communication between the embedded system and other devices or systems.

Finally, an embedded outsourcing specialist needs a robust understanding of computer hardware, including different types of memory like RAM (Random Access Memory), ROM (Read-Only Memory), and Flash memory, each with unique characteristics and uses. Knowledge of microprocessor and microcontroller architectures is also critical, as these components are often the heart of an embedded system. Familiarity with different protocols, which set the rules for data exchange between systems, rounds out the necessary competencies for an embedded engineer.

An established embedded projects outsourcing provider should be able to gather a remote embedded team within a reasonable time with the skills and tech expertise necessary to implement the client’s project.

3. Team up with a development partner that has a solid understanding of hardware capabilities

The primary responsibility of an embedded software engineering team revolves around harnessing the full potential of hardware components to enhance the benefits for the end user. Embedded engineers must comprehensively understand the hardware they are working with. Embedded projects often have varying requirements regarding computing or data processing power, memory size, and HDD or SSD capacity. 

These requirements can differ significantly based on the application and the environment in which these systems are deployed. Embedded engineers should provide ideal configurations, considering several elements such as form factors, central processing units (CPU), memory, storage, and input/output systems (I/Os).

Choosing a technology partner for embedded projects is more than just assembling a team with expertise in embedded computing solutions. Your tech partner should also be up-to-date with the latest advancements in processor technologies to deliver innovative solutions to complex projects.

4. Use Agile development strategies to maximize project efficiency

Project management in the tech industry often grapples with common issues such as extended development cycles, delayed delivery, unpredictable timelines, subpar quality, and the burnout of engineers. One approach to circumvent these challenges, particularly in the realm of embedded software development, is the adoption of Agile methodologies. These practices can significantly accelerate the product development lifecycle and help teams overcome the inherent constraints associated with this field. However, the successful implementation of Agile for combined hardware and software development can sometimes require external guidance.

To establish an efficient Agile-based operating model, the team's methodology, structure, size, tools, practices, and metrics. These elements can be established by creating a baseline map of the existing environment and product architecture. Milestone-driven release plans can involve Agile methodologies in a hardware development environment.
