When evaluating Business Intelligence Tools, what aspect do you think is the most important to look for?

The tool should have an intuitive interface and easy to use tool. It should seamlessly integrate with multiple data sources like database/clouds/API's etc.It also should have advanced visualization capabilities, customizable dashboards, and user-friendly reporting features.

Thank you! There are many good ideas.

Successful BI implementation allows you to transform data at hand into actionable insights for both strategic and tactical business decisions.This guide:  https://www.cleveroad.com/blog... will help organization owners find out all the details about how to implement business intelligence!

It is really difficult to choose the right one, in my experience, the most important thing is not the tool that we choose. The most important thing is to design the correct scope, what we need to give us the tool based on two factors, the data we want to obtain and for whom that data will be. If a good approach is made, the chosen one will be the correct one.

Total cost of ownership is often overlooked during BI product selection. Cheap products do not equal cheap ownership experiences, whether it is missing functionality which must be provided by additional products, poor integration of modules which causes duplication of effort, weak support from the vendor, high cost of maintenance or constant changes to the product portfolio.

The key factors to consider are:

Is this product right for the intended user-base? It should not be necessary to purchase one product for IT, one for business analysts and one for 'end-users'. There are considerable cost savings associated with using a single platform (not a single vendor with many products they have built or bought).

Does the product have the depth of functionality needed, and foreseeably anticipated?
Is that functionality accessible? Can an expert easily access complex, deep functionality, without the occasional or new user being overwhelmed by the interface?

Can it reach all the necessary data sources? Both inside and outside the corporation.

How fast is the user experience, both in developing reports and dashboards and in retrieving the data? Speed of both allows iterative learning and development by new and occasional users, while ensuring high productivity for expert users.

Does it work with our real world data? Too often evaluation of products still relies on superficial test on restricted volumes of data, or the lower complexity data as "it would take too long to build a fully representative testing environment" - big mistake. Identify the product(s) you believe are suitable and then bear the cost of proving they can deliver in your own use case. Too often a poor acquisition is followed by increasing spend to "make it work", when money spent earlier on selecting and proving the right tool would lead to much lower overall cost of ownership and more importantly early success and hence ROI.

Does the company have a history of good backward compatibility? You will build a vast amount of intellectual property with a BI tool. You will become dependent on the insight it provides your organization. So investigate how well you chosen product has allowed users to migrate that IP forward through new revisions of their products. Rewriting IP is a good opportunity to clean it up and start over, but it's a massive unnecessary expense if you have built what you need and it is the vendor forcing you to rewrite your work.

Use case! What and or for whom are you trying to provide reporting capabilities to and from what applications and data sources. What are the skill levels of these users - basic business users or analysts. Ease of use should be top of the list as well as a quality customer support experience.

There are many choices today around BI solutions (embedded, self-service, etc.) and finding the right one depends upon answering these questions.

Easy to use, performs well, cost, and not going to send me insane integrating it with other systems. Everything else is gravy.

Key Evaluation Points for BI Tools:
1) Ease of use – Self-service analytics and data exploration, End-user report consumption and Time to develop new reports
2) User Interface and Visualization effectiveness – If it does not look good business will not use it
3) Styles of BI Supported – Scorecards Dashboards, Operational Reports, OLAP Reporting, Predictive Analysis, Notification and Alerting
4) License/TCO – Open Source vs Enterprise Software – support and maintenance structure – development and administration costs, environment deployment constraints, admin tools
5) Performance and data scalability – Depends on the business requirements and data volume
6) Data source connectivity – Depends on the source systems that need to be integrated and backend data integration
7) Security – Authentication, Authorization, Application, Object and Data level security
8) Extensibility and API/SDK – If integration with external applications is required
9) Feature Set/Product Roadmap – scope of product features, speed of platform innovation

Most folks tend to think of UI and the flashy, sexy stuff. However, experience has proven that adopting a platform approach is key to success - a Platform that can access any data source and provide capabilities for internal and external users from the same platform, and not merely serve as a data visualization tool. The ability to do disconnected analytics cannot be discounted; Further having a platform that does NOT mandate creating a data warehouse as a prerequisite; i.e. It shoild have the ability to access operational data sources with minimal impact to the back-end systems.

I believe you have to match product capabilities to company BI strategy first and then consider infrastructure standards and internal competencies. if you do these things you should get value. The type of BI solution is important but don't be fooled by the "it's all about data visualization or big data". it is not in most organizations...

"Time to insight" is very important for me. Since the business questions arise non stop and need fast responses, going from raw data to answer a business question in the lesser time possible, with the easiest way of doing that, could be a huge differential in selecting a tool (set of tools).

User Friendly, Customization, Pricing

In the following order :

Licensing Cost
Ease of Use for End User
Functional Capabilities
Performance

1. First and foremost. Gather the detailed BI requirement from Organization needs. Answer the below questions,
a. How much GB (memory size) is required to hold / maintain organization data?
b. How much the data is going to increase by months and years?
c. How many BI users (Analyst) are going to use BI system?
d. How Critical would the BI system would be for End users?
e. What are the reporting requirements from End users? do they need simple report, visualized reports, Self service BI requirements
f. What is the Budget to build BI?
g. Is management ok to have Cloud BI?
........... like this much more information
Based on this above needs selection of BI would vary.

Typical BI tools features

1. Core BI features
DB Engine, Master Data Management, Data Quality Management, Scaleability, Performance, Hardware and Software Maintenance, Replication requirements
2. Additional features such as reporting, sharing, collaboration, visualization, etc
3. Ease of use (installation, operations, learning, etc)
4. User friendly design environment and run time environment
5. Customized Security features
6. Product Stability and Consistency
7. Good Product Support available
8. Ability to merge / mingle with Social Media.
9. Cost not significantly high/low with competitor products
10. High Productivity to develop and deploy
11. Forum / open support guidance availability

I see these are the basic BI selection criteria.

Security integration. My existing application already has a list of users and what products they have access to. Allow me to push this assignment to the BI tool or have the BI tool call out for access to a dimension. Don't make me duplicate permissions.
Ease of setting up the metadata layer (I would like to be able to manipulate it programmatically / via scripts)
Make it appear to be part of the existing application. No separate logon, run headless or allow significant LnF changes.
Licensing to match my usage not my hardware.

Most important it is to support all End-User needs; Analyst, Management, Operational

The success or failure of any BI project depends on collecting and prioritizing Business requirements and must include the following:

1. A targeted business process

2. How BI can improve the process

3. When BI will be used

4. What kind of BI is needed

5. Who will use it

6. How improvements will be measured

In most cases, BI investments need to address:

Better alignment of BI with business strategy
Improved data quality
Better integration of BI systems with other systems, such as CRM or ERP
Better understanding of user needs and requirements
Improved user training
Brainstorm ideas - on how BI can be used
Identifying business questions - gaining more detail on requirements and information needed

The most important criteria for me would be it's ease of use for non-technical users. If you have to use data analysts to develop all the reports then keep looking.

Performance and Scalability. Ease of use goes without saying.

Afordable for the company. Capacity of training. Solutions for needs

For us it normally comes down to a combination of the following:
1. Cost of implementation
2. Ease of use
3 Vendor lock in or does it use shared technology

1. Cost of implementation & Licensing Price
2. Ease of use and drill down function
3. Ease to change the source of data, as data information is keep increasing
4. Can link to multiple datasource like mssql, MySQL, excel, csv.....
5. Speed of data present BI & Drill down
6. User access rights, since not all information should be publish to all level of people

will the solution solve my present,past,and future problem. how about support should incase of downtime. performance and scalability

01> Fulfill the business requirements
02> Cost of the Implementation.
03> User friendly, ease to use
04> Real time Dashboard
05> Performance & Scalability
06> Troubleshooting and Support

“It’s better to have fewer things you trust than have a whole lot of things that are suspect,”

Support is the number one thing you think of before any other thing

Customization, Scalability, OnPrem or Cloud, Licence price v Functions you get and the resources the BI system demand in staffing.

Scalability, Performance, Security

User experience, metadata support, Performance

Speed to market, User interface, scalability, performance, and many other depending on how bad your current BI situation actually is.

Definitely, ease of use, the real-time dashboards, performance, and stability. The fact that a relative novice to Cognos is able to utilize the tool on day 1 is impactful.

When it comes to integration capabilities, which system-integrations are crucial to the solution performance, to the extent that users must be continuously informed/updated about their availability?

A package that can be used by Main Street. Too many of the BI Vendors only focus on enterprise. Organizations of all sizes have tons of data that important information can be gleaned from. Frankly, the smaller your organization, the more you need it because your risk threshold is lower.

1) Functional capabilities
2) Scalability
3) Licensing /TOC

BI tools are not easy to implement unless:

1. you have done a business need analysis.
2. you develop an strategy that provide continue support to the end users.
3. you got executive management approval.
4. you have a product maintenance plan that allows to continue to update the products.
5. you have a daily backup/restore strategy in place.
6. you have a technical team trained.

-Is BI Tool User Friendly for data modeling?

-Data blending capabilities.

- Ease of use for IT and non-IT end users
- OLAP functions
- Performance: Creation and consumption of In-memory MOLAP cubes
- Accepting integration with other OLAP engines thru MDX queries
- Easy mapping of Logical views from physical datawarehouse tables/views.
- Creation of Dynamic Dashboards and Transparent way to expose them to Mobile applications
- Scalable solutions.
- Authorization Model at very low granularity level (attribute data) to allow multi-tenant solutions.
- License model and cost

7) TCO

Self Service capabilities; ease of use; documentation and developer community

Open API interface which allow you extend functionality not covered by default. If you take one of the TOP 10 BI tools every product has cons and pros. In my practice from many projects I haven't product which 100% satisfied customer requirements

Not in order of importance:
1. Licensing cost
2. Scalability

- Ease of use
- Cost of licensing and ownership
With respect to these criterias I prefer E-Kalite Software

@ChaelChristopher i think still it means the singular. If he wanted to mean plural, the question would be "what are your most important criteria.. ".
Off course there are a lot of criteria to when you are researhing a BI tool. But every role can have different priorities. Power users or developers may want it to be easy to use, sponsor may want it not to cost too much.

@Mehmet Üskes -- Criteria is a plural concept, criterion is singular. I think the bulk of these answers are adequate...the reality being that no one selects a BI tool for just ONE reason. There are always strengths and weaknesses in a class of BI tools but if all you have is a hammer, then everything looks like a nail. Selection should be based on the basic needs of a project or an organization, and the needs of a single business user will be different than the needs of an organization that needs to OEM a vendor's solution into their own offering.

I wonder why most of people answered with writing more than one criteria and some of them have shared long lists. Is not it clear : "What is your most important criteria" ? It means you should say your MOST important criteria which has to be only one, Otherwise the question would be like "What are your important criterias.. " :)

Does the tool integrate with many data sources

A lot depends on context but important factors I've seen influence people are:

- End-user ease of use (meaning self-service and integration into the desktop today)
- Enterprise features such as integration into enterprise security
- Ease of data acquisition and ingress into the platform
- Cost
- Existing vendor relationships
- Long term support costs (when people think of it ...)

The cost is important but having a tool that is simple enough for user to use and build on but also strong enough to support complex processing and provide strong performance is equally important.
Connectors are very important, being able to use various data sources.

Integration - applicable on many fronts...
Is the platform integrated as a whole (i.e., a report created for web renders correctly on a mobile device)
Does the tool integrate with many data sources, including RDBMSs, cubes, spreadsheets, APIs...
Importing SAS, R, or PMML packages?
Integration with Office?
Does the BI vendor provide well-documented and flexible APIs?
Can the the platform be integrated with SSO and portals?

And, in order:
1. Easy for non-technical users & UI
1. Ease of Troubleshooting and Support, and Security.
1. Reporting / Visualization - dashboard, cubes
4. Licensing cost / Infrastructure requirement /Scalability.
5. Complexity/ Ease of Development effort as well as Customization.
6. Metadata support.
7. Mobility and Cloud based accessibility.

The top three are '1' as the order would change depending on the budget and size of the organization.

Ease of tapping into DB, ease of use, and available industry benchmark.

I am a user, but I compare Bi tools. In my understanding,
1. Cost
2. Complexity and time in installation
3. Security
4. Compatibility
5. ETL - Issues around it
6. Support
7. Responsiveness (Device compatibility for end users)
I guess, there will be more, but these are on top of my mind.

Ease of use, scalable

Flexibilty and suitability to requirements

After more then 15 years experience in BI Consulting,
I see as most important is:

1. Completeness of the solution (is it possible to cover all business requirements with a single BI platform )
2. Centralized administration and unified semantic layer
3. Ability to integrate with a variety of data sources
4. Scalability
5. Support and maintainable upgrades

License model fitting our startup requirements; dashboarding incl collaboration functionality; cloud based, sass capability and multi tenant; integrated lite dwh plus mdm functionality

Visualisations of data to make sense of them

(1) Ease of use
(2) Ability to integrate with a variety of data sources
(3) Company reputation

The answers already provided cover much of what I would recommend, so let me add a few items that are not mentioned:

1) Company track record. Have they delivered in the past on new features and new functions?
2) Is there a product roadmap for future development?
3) Is there native driver support for your data source(s)? Relying on ODBC for your BI tools is going to guarantee slow performance.
4) Are the major modules/functions web-based or PC-based? If you have to install software on every PC it will cost more to maintain and be more difficult to upgrade.

I hope those are helpful.

How quickly it can crunch millions of records.

Cost Effective

1. Data visualizing capability
2. Tools for ETL and Reporting
3. Ease of use
4. Implementation cost
5. Development cost

Functionality and cost. Cost to include license, infrastructure, training and ongoing support.

Ease of use, Visualization options, Interactive, accuracy when combining data from multiple data sources, alerts

You need:
type of storage: MOLAP; ROLAP HOLAP
Architecture: Stage, Landing, Reports
Integration, Analysis and Reports Tools

TCO / Functionality trade offs for the current environment with an eye on the longer term.

I am a news writer at TechTarget.com and am interested in interviewing users of BI solutions. If you are willing to be interviewed, I can assure you that I will fact check before publishing. If you found BI software that performs well or not so well, and your company will allow an on-the-record interview for a story, or if you know someone I can contact at your company for a story, I would be pleased to speak with you. Please email at dring@techtarget.com

Apart from sufficient functionality: readiness and ease to deploy and upgrade.

2-Development Effort.
3-Cost of the product
4-Maintenance.
5-Technical Support.

1 - Self-Service : Empower everyone with reports that are easy to build and share customize reports
2 - Unify disparate data sources : use data from multiple sources in a single report, (Excel, text/CSV files, any database, Web, etc.)
3 - Real-time business intelligence : makes data available on demand rather than on regularly scheduled annual, quarterly or monthly
4 - Maintenance issues and easy to implement. : centralized data management and implementing a generic solution to meet specific challenges often becomes difficult and costly
4 - TCO : have the lowest ownership costs (pricing Licensing + installation & maintenance costs + Infrastructure requirement)

1. Self Service / Ease of Use
2. Performance and Scalability to handle Big Data
3. Database agnostic
4. Good Product support and TCO

Knowing what you want to achieve with that tool

for BI platforms;
1. ease of use from end user point of view, and ability to manage flexibility for different user groups
2. ease of maintenance
3. visual capabilities
4. performance

I think the most Important criteria Is not specific feature, it's actually the matching between the customer's needs and the features of the tool. So you can write ease of use for example but if the solution is a dashboard that hangs in the CEO / CTO / CFO office then it's not relevant.
If the need is to analyze the data by only the economic department then you need a tool that is great at analyzing like Sisense or Tableau.
On the other hand if the requirements is a full-scale large-company business intelligence solution for thousands of users that maybe you Can go with more general solutions like Yellowfin.
The requirement could be embedded business intelligence then you can consider tools that made for that (yellowfin / pentaho) and don't forget Big-data That can change the picture altogether.

So, in other words, first know what your customers need then you can pick the right set of tools:
data integration, data warehouse, business intelligence GUI tool.
And you also can combine several of them for example:
1. Pentaho data integration, exasol , yellowfin
2. MySQL and Sisense (that has an internal in memory database)

Also I am the author of the course: Pentaho kettle tutorial at pentahokettletutorial.com

Ease of Use - ability to train a 'power' user. Flexible and performance options.

#1 - Ease of use without the need to know how to code as a business user. Should simply be able to search for answers or drag and drop fields to get insights.

Following this order:
1. Comprehensive, Easy & Intuitive User Interface (Scorecards Dashboards, Reports, OLAP, ...)
2. Licencing->Installation->Maintenance Costs + Infrastructure requirement (TCO)
3. Performance, scalability & Connectivity (data sources)

Cost, Performance, Ease of Use, Visualizations

Performance, Licensing Cost and User Friendly

We have found that a easy-to-use UI, Integration with our ERP/DW, and speedy performance are favored by our business users. Otherwise, the BI tool will end up being a burden of our IT team with less-than-stellar gains by the users.

It depends on the environment where you are implementing the BI solution. If you are implementing a solution in a 100% commercial company you want something very easy to use. If you are facing an organization full of geeks you want something that can be twisted in every single way... And so on.

I would start by saying that there is not a single criteria that will magically make you decide on which BI tool to use. First things first, requirements should be analyzed in the perspective of scalability(that will lead to performance as well), licensing/maintenance/training cost, target audience and tools available. In regards to the last point, analysis on the data source connectivity provided, ETL processes made available, semantic layer and reporting/analysis tools provided should be considered. It can be that not only tools from one vendor will do the job for you so integration with other tools should also be considered.

Good Feedback.

SO based on feedback, all I can add is evaluate
SCALABILITY :
1) Your need : How much Data
2) usage: just for a few months or Long term example : 15 years
3) IS the data model going to change over the years or period.
4) will their be new feeds over time.
EASE OF USE
3) How many reports : this is where ease of use,dash boards come in picture
ETL:
1) extract , transform load functionality . This is important , if your ETL guy or girl leaves the company , you are screwed , unless tool is able to simplify the ETL process , that you can do reverse engineering.

COST:
1) based on your answers above you can choose the appropriate BI tools out there.

PERFORMANCE : Non related to tool
1) this depends upon your HARDWARE, Data model and architecture , and fine tuning of queries...in addition maybe populating the Data marts or views and / or Reporting universe.

Check support for Analytics, Data Insights, Visualization and data as service

1. Easy of Use
2. Licensing cost

At risk of repeating others, ease of use, scalability, security (user and row level for example) and TCO are probably top of my shopping list. Compatibility with other tools also quite important (for example R or hosting visulisations on intranet/internet)

Scalability and Performance
Maintenance Requirements
TCO
Product Roadmap

Feature Set, Ease of use, mass deployment capabilities, and licensing costs..

Performance, understandability and user-friendly

The scale at which you are going to implement the BI tool. Everything else has a solution But you can't go using in memory tools for a Global enterprise.

It is important that a Business Intelligence solution supports the principle of ‘create a report once; run on every device’. People today use tablets, smartphones very very often.
Second, performance? a good response time is also important.

Following this order:
1-Licence cost
2-Visualization data (dashboard, reporting,..)
3-Performance (Load/process data)
4-Security
5-Easy for non-technical users
