The Review
Feedback summary: 

Careful attention to detail is evident in all project deliverables and key milestones are rarely missed without merit. While their verbal English was sufficient, it's written form could use improvement across the majority of the team. 

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

Joingo is a telecommunications company developing applications for mobile devices. I am the quality assurance manager of the company, in charge of testing automation processes for our developed solution. I have been working in Silicon Valley since the mid-90s when the internet era started, in companies like Netscape, Yahoo!, AOL and other major vendors.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JazzTeam?

I have created my own test script, which was successful within the company, but continuing to develop it would be a full-time job. I couldn't continue to handle QA management in parallel with writing test automation scripts, so we agreed to outsource the project to a supplier. We then began the processes of identifying and vetting companies that might be able to take over writing the scripts.

SOLUTION

What was the scope of their involvement?

JazzTeam has provided manual and automated testing for our company.

I currently use 3 people from JazzTeam's group, including a full-time test automation specialist and 2 manual testers working on our console application and content testing for mobile devices. They're working together on one big project.

All bug fixing is done on our side, in Silicon Valley. JazzTeam has no direct access to our product code, as part of our strict policy.

How did you come to work with JazzTeam?

Since I lived in Belarus for more than 10 years, I've made many connections with companies there. I knew that there are some unique government requirements in that area, like only being allowed to attribute the term "software engineer" to people who have Masters of Science degrees in the field. It's also a very stable country from a business standpoint. I suggested using a team from that area, provided a couple of options, and ultimately selected JazzTeam. We gave them a trial, working on a proof-of-concept over a month's period. JazzTeam was successful, integrating into a highly professional environment, using Jenkins, Asana, and so on. Our lead engineers reviewed the work and were very happy.

What is the status of this engagement?

I've worked with JazzTeam for 3 years at a previous company, and 2 years and 1 month for the current one.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

There have been many positive changes that resulted from JazzTeam's work. Releases are done on a weekly basis, but builds are done daily. Our process has become much different due to the time difference with JazzTeam: they are constantly working during our nighttime. In the morning, we can review the bugs discovered and start working on them. The biggest advantage has been the dramatic increase in efficiency.

We have annual reports for our vice president. Overall, JazzTeam has reported around 500 bugs, covering 1,200 test cases for our products. 70% of our products' functionalities are tested with every build. JazzTeam has created continuous integration, something which our company never had, issuing automated tests with every new build. Each test is run for around 200 hours. If any critical failure is discovered by the script, the build is rejected. We are given detailed reports featuring screenshots, which are done automatically. The whole process is very well-organized and documented. 

How did JazzTeam perform from a project management standpoint?

JazzTeam has worked efficiently on all the tasks provided to them. If I see a need for utilizing additional resources in order to accomplish a task, JazzTeam will provide it without any delays. I'm a very picky manager, but I've been happy with the quality of resources from JazzTeam.

Each task is assigned a number of hours. Technical communication is done through Skype. We have a 30-minute scrum meeting with JazzTeam every night, reviewing a status report, providing current tasks and any training needed. We use email for formal communication like invoicing.

What did you find most impressive about JazzTeam?

I've worked with other suppliers and found JazzTeam the easiest to work with and manage. They've acted as a sort of black box: I can simply tell them what to do and be given the right resources for the task. This was highly appreciated by our management.

Are there any areas JazzTeam could improve?

We sometimes had issues with the quality of the English writing in our bug reports. Since it isn't JazzTeam's native language, some passages weren't as easy to understand. Aside from this, there isn't anything.

What tips or recommendations could you share that might increase the likelihood of success with JazzTeam?

Clients should define their goals clearly in order to avoid misunderstandings on JazzTeam's side. They should also verify that all instructions have been understood correctly.

The Review
Feedback summary: 

Highlights include responsiveness and flexibility when it comes to project management. English skills were an area for possible improvement. 

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

We are a professional integration solutions provider focusing on backend ERP systems, primarily the AS/400 IBM i series. We have a strong development team for this platform. It's an older platform but it's still popular within the insurance, manufacturing, and retail industries. We are a MuleSoft partner, which is a provider of integration platforms and solutions. I am the vice president of integration and cloud solutions.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JazzTeam?

We were working on a MuleSoft connector for AS/400 and completed the development in-house. One of the steps required bringing the solution to a standard that MuleSoft could certify. This is a very rigorous process for ensuring code quality, so we were looking to outsource the work.

SOLUTION

What was the scope of their involvement?

JazzTeam completed the work on our MuleSoft connector and we've since worked on numerous projects. We have used JazzTeam for building custom integrations based on the MuleSoft platform. JazzTeam has mainly provided development and testing. We have worked with 2 JazzTeam developers.

How did you come to work with JazzTeam?

My business partner got an email from a marketing company working with JazzTeam. He decided to respond, which is rare but still happens. We had a quick exploratory call and found that there was a good vibe. During my conversations with JazzTeam, there seemed to be a good synergy between our companies. We decided to give them a small internal project, before using JazzTeam for our customers.

How much have you invested with JazzTeam?

We paid $20,000 for the connector project. We have another ongoing project with JazzTeam which will have a much higher budget, close to $40,000.

What is the status of this engagement?

We started working with JazzTeam in August 2015, and have ongoing projects.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

The connector was certified by MuleSoft and was published in their repository. JazzTeam fulfilled all requirements and was spot-on in terms of deliverables. I've liked their team and responsive management. JazzTeam addressed all of our questions and concerns surrounding possible risks.

How did JazzTeam perform from a project management standpoint?

JazzTeam stuck to our timeline. We used Asana for tracking tasks and progress and Excel files for time tracking. That was enough for us since we were only using 1 developer at the time. Now that the scope has been ramped-up, we are using Jira for project management.

What did you find most impressive about JazzTeam?

JazzTeam got the job done. This may not be unique, but working with them gave me a good feeling.

Are there any areas JazzTeam could improve?

My first language is Russian and the same is true for JazzTeam's staff. Some of their people speak English better than others, but we've been lucky in this regard, so far. There were a few communication issues, but they never affected our projects.
