Appian is very efficient, allowing us to build a lot of applications within a financial year, making it cost-effective.
Developing that same project in OutSystems can be completed in around 40 to 50% less time, requiring only six resources.
They have removed the costs associated with on-prem infrastructure, including data center costs, power costs, and physical server costs.
The return on investment is good when implementing for ourselves and for other clients.
Manually, there are huge numbers that come up because these integrated tools help organizations make the right decisions with all the information in one place, while manual methods lack visibility.

I have contacted them four to five times over the past two years, and they have been quite helpful.

On a scale of one to 10, Appian rates as a nine for scalability.
Initially, without much coding, I can easily handle five thousand records.
Appian is scalable, but it depends on how you build your applications.
They can be deployed vertically and horizontally, supporting as many deployments as needed.
There are no limitations or performance issues with ServiceNow; it is cloud-based, so it is highly scalable and performs well.
It is capable of vertical scaling with no issues.

I haven't faced any issues with stability; I've rarely seen any downtime.

Room For Improvement

Appian needs improvements in flexibility, integration, scalability, team collaboration, mobile features, documentation, licensing, and handling complex processes.
OutSystems faces performance and integration issues, high licensing costs, and needs improvements in support, automation, UI, and documentation.
ServiceNow needs to enhance user interface, licensing, support, integration, and analytics to improve user experience and satisfaction.
It has room to improve for use cases where the users are public facing, where anonymous users could come to a site and run a business workflow or interact with some data.
If there is a very complex process that includes a lot of data transitioning and memory-centric processes, it consumes a lot of memory.
I would like to see more enhancement in the user interface to allow more freedom in designing the sites and pages.
It is crucial to be aware of which module corresponds to which application in real-time projects, as there are multiple applications.
I would like to see more integration between the use of artificial intelligence to speed up the process delivery time.
What I would like to see is more servicing business analysts in the next release of OutSystems.
It makes no sense in my opinion, and they should offer the team at the front to help customize the product to fit each company's needs, as every company has different demands and forms of submitting a request that need adjustment over time.
There is a need for bug or error tracking in ServiceNow.
Their customer support could make it a great solution, not just product support but also their relationship with partners and training initiatives in different regions.
 

Setup Cost

Appian offers flexible pricing with cloud and on-premise options, but costs can rise with usage and require negotiation.
OutSystems is costly, suited for larger enterprises, with yearly fees varying by usage, covering licenses and infrastructure.
ServiceNow is costly with complex licensing, requiring negotiation and flexibility, especially burdensome for small and regional businesses.
On the pricier side, both Appian and Pega are enterprise-level solutions, placing them on the slightly higher side.
The pricing of Appian is based on the number of users and generally ranges from 70 to 100 USD per user per month.
The price of Appian, on a competitive landscape, is a little bit on the higher side for companies, rating maybe a 6.5.
Subsequent users can be added at an additional cost per user; exact pricing details can be found on the OutSystems site.
ServiceNow's pricing can be justified if more functionality is required.
ServiceNow does come with a price.
ServiceNow is expensive for all regions.

ServiceNow offers flexible customization, fast development, and strong integration, enhancing efficiency across IT, HR, and finance with robust reporting.
The zero-code integration feature is remarkable, allowing for ease of data transfer and workflow enhancement.
Appian is aiding in leveraging AI technologies in multiple ways: one way is for developers, as they make development efficient and quick by enabling developer co-pilots across various phases of the application, which helps design Appian quickly and provides suggestions along the way.
It is easy for me to define the process and create configurable workflows.
OutSystems offers a lot of reusable components and solutions that I can simply drag and drop and use, which has a significant impact on project delivery time.
OutSystems has a very good learning curve for developers.
I have recommended it in situations where very rigid enterprise structures are blocking them from being agile.
ServiceNow provides a wide range of functionality, covering all the necessary modules, unlike Jira which is primarily for IT.
Automation capabilities are impressive, bolstered by a vast repository of out-of-the-box connectors and plugins that facilitate integration with various applications worldwide.

Featured Reviews

Kunal Sharda - PeerSpot reviewer
Experience enables seamless automation and elevates process efficiency while embracing innovative technologies
The features of Appian that have proven to be the most beneficial are its capability to create processes and integrate with external systems while ensuring data consistency across all the systems. The latest features of Appian are quite useful around the UI/UX design and the artificial intelligence integrations. Appian is aiding in leveraging AI technologies in multiple ways: one way is for developers, as they make development efficient and quick by enabling developer co-pilots across various phases of the application, which helps design Appian quickly and provides suggestions along the way. Another way is through AI Skills, which can be integrated anywhere in the process model to leverage artificial intelligence for tasks such as extracting data from documents, summarizing information from documents or long paragraphs, and building custom prompts with Appian. Appian also utilizes AI for business users, providing a feature called process each view, enabling business users to create their own dashboards, reports, and gain insights from their data and processes using artificial intelligence. It's multi-fold and always growing.
Sukrut Joshi - PeerSpot reviewer
Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.
Nikhil Gohil - PeerSpot reviewer
Enables effective incident management and seamless workflow automation with valuable mobile accessibility
I haven't thought deeply about improvements for ServiceNow or what might be missing right now. There are so many modules and features in ServiceNow that I haven't explored them all, so it's hard to say what might be missing or should be improved. I suggest making the cost more affordable for smaller companies.
