The Review
Feedback summary: 

The OSSystems team employs a broad variety of skill sets to create high-quality, cohesive deliverables. The team integration process has been fluid and effective. Emphases on collaboration and communication have been key in developing a long-term partnership.

BACKGROUND

Introduce your business and what you do there.

I work with an industrial IoT software company that supports industrial customers in North America and Europe.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with OSSystem?

We were looking for the right team to augment our developers in creating an infrastructure on Amazon Web Services (AWS).

SOLUTION

What was the scope of their involvement?

We’re building an AWS infrastructure to support IoT devices in industrial settings. The software collects data from sensors and equipment, puts it in the cloud for storage and parsing, aggregates a data lake, and creates visualizations and predictive analytics. It’s a complex project that involves extensive database/system integration.

What is the team composition?

Their team fluctuates between eight and 11 members.

How did you come to work with OSSystems?

We hired a search firm and they worked with us to create a shortlist. We interviewed several companies and found that OSSystem offered the broadest variety of skill sets.

What is the status of this engagement?

We started working together in August 2016. The engagement is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’ve completed several prototype customer projects. There’s a constant process of improvement on how best to devote resources and set our project schedule. In the long term, communication has been very fluid and there’s been a strong sense of collaboration throughout the project. Problems are bound to arise in development partnerships, and some teams are better at addressing them than others. The OSSystems team works proactively to solve problems quickly and thoroughly.

How did OSSystems perform from a project management standpoint?

We work within an Agile process and collaborate via Jira and Slack. The team integrated with our team very effectively, and the resulting process was incredibly fluid. Their English was solid and the team was very easy to work with. Overall, their project management has been excellent.

What did you find most impressive about them?

Teamwork and collaboration require solid cultural alignment in terms of development strategy. OSSystems takes on technical challenges in a way that complements our team’s approach.

Are there any areas they could improve?

No, nothing comes to mind.

Do you have any advice for future clients of theirs?

These partnerships are all about communication. Make sure to leave the door open to foster constant communication throughout the project. We don’t need a constant stream of meetings to keep our development process going, but we meet with them on demand when issues comes up. This was incredibly effective for our needs.

Feedback summary: 

Although the platform is still in the pre-launch stages, OSSystem earned positive feedback on the professionalism and attractiveness of the UI design. Their quality of work, daily communication, and proactiveness has provided depth and range in their professional relationship.

BACKGROUND

Introduce your business and what you do there.

We are a data analytics software as a service (SaaS) platform and I am the cofounder.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with OSSystem?

We engaged OSSystem to build the frontend for the customer facing portal while we built the backend of analytics machine learning engine.

SOLUTION

What was the scope of their involvement?

I came to them with ideas and an initial wireframe. They got to know and understand what we were trying to do, and then they led the process. They expanded the functionality, along with the user interface (UI) design.  They had a really good understanding of what we wanted to achieve from a user experience point of view.

What is the team composition?

We’ve had the same project manager since the beginning of the project and he’s been fantastic. We communicated during the main development phrase, but we also have weekly updates including, delegation, feedback, and bug fixing. Overall, he’s been very responsive. We have also worked with a number of developers but we go through the project manager, rather than the individual, and that worked well.

How did you come to work with OSSystem?

At the early stages of any innovation project, software development can be expensive and risky. Initially, I put out a proposal through Upwork and OSSystem responded. But I elected to go with an independent freelancer. After two weeks when that clearly wasn't working out, I contacted OSSystem. I needed to have a professional services firm onboard that could provide the depth and range in order to get a professional product and outcome. That was two and a half years ago and we're still a very happy customer.

What is the status of this engagement?

I have been working with them since September 2015.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We're entering the commercial launch phase now. Trials with key customers have been extremely successful, and feedback regarding the professionalism of the design and user experience has been very positive.

​​​​​​How did OSSystem perform from a project management standpoint?

We talk daily to their project manager on the operational aspects of the project. Then sometimes I will have a separate conversation with the CEO of OSSystem from an account management aspect on how things are going. Our needs are always first and foremost, their written clarifications are good, and they’re proactive in leading conversations.

What did you find most impressive about them?

Their value for money is very good but high quality. The stability of their team was another thing that impressed me. The continuity of people, the project management, and consistency throughout the project was great. Lastly, I was impressed with their responsiveness and customer focus.

Do you have any advice for potential customers?

With any software project you've got to know what you want to achieve. The success of the project and your ability to get high quality outcomes, really depends on your clarity as a customer and what you're expecting from them as a service.
