We've recently created a scrum team to create a new "client following system" using OutSystems. So for now it's just one department using OutSystems. Our old, legacy system does not serve our needs anymore and is not flexible at all. So with OutSystems we are building a new one from scratch. Two of us are new to OutSystems (and IT) and learned to use it in a few months. We hired three external experts to build and teach the juniors, so we could start building and delivering value immediately.
  • Being low-code, even people without any experience can start building with OutSystems immediately.
  • OutSystems has a great and very helpful community, giving advice and pre-build features to beginning engineers.
  • OutSystems is very flexible and easy to use; it enables us to build something useful within minutes.
  • Being relatively new in the IT world, I could use some kind of quick reference guide inside OutSystems (instead of going to the website or forum)
  • Filtering aggregates could perhaps be done in an easier way. I struggle with them, sometimes.
  • I'd like more pre-made layouts.
I think OutSystems is the ideal program to use when you want to work in a lean and agile way (and who doesn't want that?). OutSystems is easy to learn, flexible and highly intuitive. Even without any former IT experience, I was able to build and develop quality features for our new "client following system" within a few months, thanks to OutSystems being low-code.

  • OutSystems helps us becoming agile.
  • With OutSystems we can deliver value every two weeks instead of having to wait months for a new update.
Easier to learn and use. More flexible.
OutSystems customer support is easy to reach. When there's a problem, I can easily send a ticket to them. After that, they contact me very fast and help me in a great way, even in the weekends. They are thinking along to find a solution for the problem and offer great help in actually solving the problem (in our case a part of our database got deleted accidentily).
Our company has a scrumteam, in which we have developers, testers, a scrum master and a product owner. We have four developers in our team; these are the persons using OutSystems. We have two senior developers and two junior developers, at the moment. The software we create using OutSystems is used by the entire company (about 90 people) and our client (a few thousand).
Our team of developers consists of two external engineers and two full time in-house engineers. They need to know the OutSystems system (and preferably have an 'associate developer' or even 'professional developer' certificate) to be able to support OutSystems.
  • Replacing our legacy software system
  • Building new software to support our business processes
  • Monitor our business processes
  • -
  • We might use OutSystems to build more and other software
We are very happy with OutSystems and our developers deliver good work. OutSystems lets us build new software on a regulare (2 weekly) basis, which is highly flexible and adjustable. Even without very much experience, our developers manage to build usefull software, which is working a lot better than our previous (legacy) software.
Before we started with OutSystems, we uses Microsoft Navision. We decided to replace this, because it became a not-so-flexible legacy software package, which we were not able to adjust ourselves. We needed a product which would offer us a way to develop new software to replace the old software, at a fast pace and with an ease of use. With OutSystems, even developers with little experience are able to build good, working software, which is highly flexible and easy to maintain.
  • Product Features
  • Product Usability
The most important factor to choose OutSystems was the fact that it's a Low-Code platform, so we could train in-house employees - without much software developing experience to use it and build with it. Besides, OutSystems is the perfect system to use in combination with an agile way of working. The scrum framework gives us the opportunity to deliver new working pieces of software every two weeks, making it possible to expand our new software over time while using the software at the same time.
We wouldn't.
  • Implemented in-house
Change management was a minor issue with the implementation
It is very important to manage people's expectations. Employees expected a finished product straight away, while the OutSystems team was told to build a mvp at first. So when presenting the mvp software, there was some disappointment in the business. Also, we had some developers from our old software platform, who were not really giving OutSystems a chance. So with them, there should have been a better talk before making them OutSystems engineers.
  • Expectations
  • Unwillingness to change
Manage expectations properly.
There was one incident where we accidentally lost a part of our database. This was on a Friday afternoon. We had no real hopes things would be solved before the weekend, but we got a call back immediately after we sent in a support ticket. The OutSystems support helped us getting a backup of our missing date and guided us through getting it back in our live database. So before the weekend, everything was solved. Amazing.
  • Create websites
  • Create (web) applications
  • Debugging is sometimes troublesome
The mobile interface works great. OutSystems has prefab and custom mobile interfaces, all very easy in usage.
I am really happy using OutSystems in my work. It gives me the opportunity to create good working software without having had very much IT-experience before. It also made me more interested in the background of IT and learning different languages.

OutSystems has become the core platform for two different start-ups that I did in the past 3 years. At first, we needed a revolutionary way to create new innovative solutions & products at a speed never seen before. These new products needed to go from idea to market in weeks not months.
Enhancements need to rollout in days not weeks. Specifically, the products and services we created are B2C and B2B for Dental & Vision financial products and healthcare provider customers.

As we had amazing success creating products & services for our B2B2C customers, we then decided to forego SaaS-based Sales, Service, and B2B On-boarding and we built it ourselves using the pre-build sales & cases apps (from OutSytems) and the BPM capability in OutSystems for B2B On-boarding.

In short - at the startup that I did, we are using OutSystems as the core for the entire business and integrating it with 3rd party services like Office 365, Google G-Suite, RingCentral, etc.

  • Skip prototyping phase - we create very quick designs that actually use our brand standard experiences and connect to real or stub services directly in OutSystems. We've found we co-create in OutSystems. The result is our "prototypes" are really 1st release candidates.
  • SWAGGER 2.0 - AWESOME! If you have access to swagger APIs, integration is so very simple, fast, and robust. Click click click - done! Then the swagger API looks just like any other module that your app needs to access.
  • Web, Mobile-Web, and Native all in ONE platform. We all have heard the dream and promise of "write once, run everywhere." OutSystems is the closest I have ever seen us come to that vision in almost 30 years in software. We truly have ONE module for Web & Mobile web (all responsive out of the box with SilkUI). We truly have ONE module for both Android and iOS thanks to the ReactJS-based solution from OutSystems.
  • LOW-CODE Heaven: No longer to we spend our life slinging code. Now, the OutSystems "robots" generate all the code for us. I will say it's super clean too. I tried to hand-build code that runs faster... I couldn't. On average, OutSystems generated code was 40% faster than mine both on the .NET and SQL side.
  • This is a hard one - I'd say continue to expand support and integration of micro-services. It's come a long way and certainly works - but keep on pouring the gas on micro-services as it's a huge part of our ecosystems.

It's excellent as a "swiss army knife" for creating everything from high-end native mobile apps to responsive web apps and even headless API services.

The built-in BPM is a good general purpose solution if you need it embedded in your apps. However, if you have extremely complex and large-scale BPM needs that span large organizations, you may want to consider a specialized BPM and have OutSystems create the user experience and connect into the 3rd-party BPM.

  • We created new products and services 10x faster than first planned and at a cost roughly 1/2 of what was quoted by development partners/agencies that were "hand-coding".
  • In short, our two start-up companies would not have launched without it.

Most complete solution. Beyond the super fast ability to create high-quality web and native mobile apps, the built-in analytics have proven to almost eliminate the need for added overhead of analytics tags.

I've been following OutSystems for 3 years and the pace of innovation and their investment in the platform is stunning.

Lastly, the developer community is excellent - when I am faced with a particularly hard or unfamiliar challenge, the community typically has a solution the same day - often it's already been solved and there are pre-build free components or at least a post that describes the solution.

Digital Center of Excellence and Digital IT
General IT and customer service skills
  • Internal apps for team productivity and communications
  • Consumer self-service
  • Consumer marketing & messaging
  • I assumed we would have to build most apps from scratch - instead I found that the FORGE had a TON of pre-built apps, modules and widgets that really sped up our development.
  • The OutSystems community is VERY vibrant and helps us think of solutions differently and solve business challenges even faster.
  • Retail apps for consumers, healthcare providers and employers
Simply revolutionary!

  • Product Features
  • Product Usability
  • Product Reputation
  • Prior Experience with the Product
  • Vendor Reputation
  • Existing Relationship with the Vendor

Product features - it truly is a Swiss Army Knife. We can create anything!
I would not change it - we picked the top 5 solutions on the market based on paper evaluation. Then, we built apps 5 different ways ... after a week two were eliminated because they were too difficult to use. For 3 months we created apps using 3 different platforms - OutSystems was the only one left standing at the end. We either "broke" the others or found we had to go outside the platform to do customer extensions. While we CAN bring custom code extensions into OutSystems - I found we didn't need to and after 3 years still have not.
  • Implemented in-house
Training then 2 month pilot then rollout to small SWAT team for on-going build.
Change management was a major issue with the implementation
Production deployment into your own cloud environment can be tricky unless you have IT staff that are already skilled in your cloud (e.g. AWS or Azure, etc)
  • Getting folks pulled out of their normal day-to-day work
In a large company, patiently and consistently work the behind the scenes politics with business and IT partners across the firm. This is transformational - you will need a solid set of key business partners to lock arms together to move forward.
Outstanding support
One time, after a platform upgrade, I had a few modules that would not build. They helped me resolve it quickly the same day.
  • Simple layout of the PROCESS - UI - LOGIC - DATA construct for each app
  • Unless you are a CSS guru, working on refining the UI design to be very custom can be tricky ... but it's the nature of CSS.
AWESOME for testing for sure!
super easy

Outsystems is used to fill-in the gaps between SOR's and BP.
  • Easy to begin
  • Robust low code solution
  • Layout can be cumbersome
Really good for scoped process automation. Can be difficult to manage as the size turns more toward monolith.
Low-Code Development
  • Time to market is key differentiation
We have not adopted at current organization. Eventually, we will.
Even during evaluation the support team still provides an excellent support experience.
I had a big demo for another Director and had a problem with my personal environment. The OutSystems support team helped me get it sorted out, very quickly.
  • Entity Creation
  • Screen Scaffolding
  • trueChange
  • Version control - concurrent development
Outsystems Now is awesome
The tool doesn't get in the way of developing software.
