In his own words, Nazim explains why he wanted the engineering team to start using GitLab:

 “I wanted them to switch away from SVN. I needed a server application to manage repositories. The common tools that were around just didn’t meet the requirements. Most of them were too simple or plain...GitLab provided all the required features. Also costs had to be low, since we don’t have a big budget for those things...the Community Edition was perfect in this regard.”

 #### Frustrations
 ##### Adoption to GitLab has been slow
-Not only has the engineering team had to get to grips with Git, they’ve also had to adapt to using GitLab. Due to lack of training and existing skills in other tools, the full feature set of GitLab CE is not being utilised. Steven sold GitLab to his manager as an ‘all in one’ tool which would replace multiple tools used within the company, thus saving costs. Steven hasn’t had the time to integrate the legacy tools to GitLab and he’s struggling to convince his peers to change their habits.

 ##### Missing Features
-Steven’s company want GitLab to be able to do everything. There isn’t a large budget for software, so they’re selective about what tools are implemented. It needs to add real value to the company. In order for GitLab to be widely adopted and to meet the requirements of different roles within the company, it needs a host of features. When an individual within Steven’s company wants to know if GitLab has a specific feature or does a particular thing, Steven is the person to ask. He becomes the point of contact to investigate, build or sometimes just raise the feature request. Steven gets frustrated when GitLab isn’t able to do what he or his colleagues need it to do.
+Nazim’s company want GitLab to be able to do everything. There isn’t a large budget for software, so they’re selective about what tools are implemented. It needs to add real value to the company. In order for GitLab to be widely adopted and to meet the requirements of different roles within the company, it needs a host of features.

 ##### Regressions and bugs
-Steven often has to calm down his colleagues, when a release contains regressions or new bugs. As he puts it “every new version adds something awesome, but breaks something”. He feels that “old issues for "minor" annoyances get quickly buried in the mass of open issues and linger for a very long time. More generally, I have the feeling that GitLab focus on adding new functionalities, but overlook a bunch of annoying minor regressions or introduced bugs.” Due to limited resource and expertise within the team, not only is it difficult to remain up-to-date with the frequent release cycle, it’s also counterproductive to fix workflows every month.

 ##### UI/UX
-GitLab’s interface initially attracted Steven when he was comparing version control software. He thought it would help his less technical colleagues to adapt to using Git and perhaps, GitLab could be rolled out to other areas of the business, beyond engineering. However, using GitLab’s interface daily has left him frustrated at the lack of personalisation / control over his user experience. He’s also regularly lost in a maze of navigation. Whilst he acknowledges that GitLab listens to its users and that the interface is improving, he becomes annoyed when the changes are too progressive. “Too frequent UI changes. Most of them tend to turn out great after a few cycles of fixes, but the frequency is still far too high for me to feel comfortable to always stay on the current release.”

 #### Motivations
-Harry has been using GitLab.com for around a year. He roughly spends 8 hours every week programming, of that, 2 hours is spent contributing to open source projects. Harry contributes to open source projects to gain programming experience and to give back to the community. He likes GitLab.com for its free private repositories and range of features which provide him with everything he needs for his personal projects. Harry is also a massive fan of GitLab’s values and the fact that it isn’t a “behemoth of a company”.  He explains that “displaying every single thing (doc, culture, assumptions, development...) in the open gives me greater confidence to choose Gitlab personally and to recommend it at work.”  He’s also an avid reader of GitLab’s blog.

-Harry works for a software development company which currently hires around 500 people. Harry would love to use GitLab at work but the company has used GitHub Enterprise for a number of years. He describes management at his company as “old fashioned” and explains that it’s “less of a technical issue and more of a cultural issue” to convince upper management to move to GitLab. Harry is also relatively new to the company so he’s apprehensive about pushing too hard to change version control platforms.

 #### Frustrations
 ##### Unable to use GitLab at work
-Harry wants to use GitLab at work but isn’t sure how to approach the subject with management. In his current role, he doesn’t feel that he has the authority to request GitLab.

 ##### Performance
-GitLab.com is frequently slow and unavailable. Harry has also heard that GitLab is a “memory hog”  which has deterred him from running GitLab on his own machine for just hobby / personal projects.

-Harry has an interest in UX and therefore has strong opinions about how GitLab should look and feel. He feels the interface is cluttered, “it has too many links/buttons” and the navigation “feels a bit weird sometimes. I get lost if I don’t pay attention.” As Harry also enjoys contributing to open-source projects, it’s important to him that GitLab is well designed for public repositories, he doesn’t feel that GitLab currently achieves this.
