Strumento adeguato a visualizzare insight nei dati aziendali

4,0 8 mesi fa

Commenti: Nelle mia esperienza l’uso di Tableau mi ha permesso di definire in modo oggettivo e monitorarle nel tempo le performance dei dipendi del gruppo. Questi ci ha permesso di mettere a terra operazioni atte ad aumentare l’efficenza delle persone che lavorano con noi. Ammirabile la capacità del software di creare report personalizzati con uno sforzo non elevato.

Aspetti positivi:

Tableau ha rivoluzionato il modo in cui approcciamo alla gestione delle performance dei nostre risolse. Caratterizzato da robuste capacità di visualizzazione dei dati, con caratteristiche anche predittive, ci permette di studiare le performance di ogni dipende ed esplorare nuove tecniche per mantenere elevato il morale e l’efficienza valutandone oggettivamente il riscontro.

Aspetti negativi:

Punto critico è la complessità dell’integrazione in SalesForce per usare il low code. Il software è poi poco scalabile.

Commenti: Insightful experience. Best for turning data into actionable and strategic insights.

Aspetti positivi:

Tableau helps us understand and appreciate data and what it means to the organization in improving operations and efficiency. Familiarizing ourselves with data filtering, grouping and segmenting. It is key in improving the process of data analysis by eliminating defects. It has eventually improved customer experiences, allows us to make better decisions and helps guide our marketing strategies towards success.

Data exploration on steroids.

5,0 mese scorso Nuova

Aspetti positivi:

Its outstanding visualization capabilities, has appealed to me the most. The quality of my data visualization activity on Tableau is far superior to what I have gotten from substitute business intelligence or analytics tools. Tableau's infusion of generative AI into my data visualization and analysis experience, enables me to integrate predictive modeling into my Tableau workflow, thereby improving the quality of insights I generate from my data.

Aspetti negativi:

Tableau comes with a steep learning curve and it is simply not for early stage data professionals. To learn to use Tableau effectively, a user must have had experience using lesser visualization platforms in the past.

I just love it.

5,0 mese scorso Nuova

Commenti: It is just great. Functionality, UX. What often stays underappreciated is the Tableau community. Even though the support far from being the best one (I guess company grew too big), one can always find the answers in the community or simply share a sample workbook and others will help.

Aspetti positivi:

I love almost everything about the Tableau. It is a pure joy to create and analyze report. The data visualization capabilities are simply the best on the market and it is so easy to use that it is just mind-blowing. One can connect Tableau workbook to almost any imaginable data source and in a matter of minutes create a great report.

Aspetti negativi:

It is really hard to think about the cons, but if it is really necessary then Tableau Prep can be quite slow if the file tend to combine more than three sources with the number of columns exceeding a 100. Even if the number of rows is fairly small (less than 1000).

Tableau stands out as one of the most polished and visually appealing reporting tools available. The interface is impressive and facilitates a user-friendly setup experience.

Tableau is Fantastic for Shippers

4,0 mese scorso Nuova

Commenti: Overall I’ve really enjoyed the program. It puts data into visuals that we can then share with our carriers. We have the ability to use it for inside information or carrier facing information.

Aspetti positivi:

As a shipper who is always looking for solid carriers this program provides unique visuals that we can show our carriers. A lot of carriers are used to just seeing the data in an Excel format, so having the visuals elevated their experience with us.

Aspetti negativi:

Tableau can be a little tedious and has a less intuitive program than other systems. Once you overcome the learning curve it is a great system.

A very intuitive business intelligence tool

5,0 4 anni fa

Commenti: I started using it while I was making my MBA and I was amazed at the easy of use and the possibility to make chart in a very powerful way beyond excel. Later on, when I was asked to do some complex representation of many parameters, Tableau has been the best and easiest option, beyond other 3 options I have tried from major sellers

Aspetti positivi:

- Very intuitive way o assemble data, no need for programming or special commands - Easily change data from numeric to alphanumeric - The most common and useful charts are available - Easy to breakdown data into several clusters - I once plotted 6 parameters in a 2 dimensional chart: X, Y, bubble size, color, name, icon - You can build special read-only docs with the functionality to be read by Tableu Reader (as in acrobat reader) - You can customize label, axis, trend and references lines

Aspetti negativi:

- Eventually some very specific charts are not there as chord, tornado, tree maps, nodes, gauges, alluvial diagram, dendograms - Even with all the clustering, it lacks statistical analysis as Anova, hypothesis test between two set of data, normal probability plot

A premium option at a premium price point

4,0 3 anni fa

Commenti: Overall Tableau is a great BI/Visualization tool where the only limitations are what your team can do with it. The platform itself has every bell and whistle you could want and provides a ton of customization for various use cases.
The challenge arises when moving to the logistical management of the platform, specifically around access, user education and price. While it might be great for individual organizations, our use case of deploying dashboards to hundreds of clients just isn’t what Tableau was built for.
If you have the right use case and team to support it, it’s a fantastic option. But if you’re lacking in those areas (or perhaps want a tool with more automatic BI/AI capabilities), there’s likely a better option for your organization.

Aspetti positivi:

There is a reason that Tableau is synonymous with data visualization tools to many people and organizations. It’s a premium product that can do pretty much whatever you want it to. Tableau’s features are limitless and with the proper resources to maintain and deploy it, you’ll rarely identify capabilities that it doesn’t have. It is truly a BI tool that enables your team to overcome any obstacle they face. I specifically enjoyed some of the advanced visualization capabilities of Tableau that more “basic” tools don’t offer. The time series visualizations are easy to configure and are always a crowd favorite. The ability to deploy on-premise or in the cloud means that organizations can configure to their preference. All in all, it is an incredibly powerful tool that leaves very few stones unturned.

Aspetti negativi:

The three biggest drawbacks to our organization continuing with Tableau were ease of use, cost scalability and functional scalability. Tableau is not the tool for organizations that lack technical resources. It’s not as “plug and play” as other options on the market and requires significant training of architects to fully take advantage of all its capabilities. Tableau also isn’t the ideal solution if price is an obstacle in your organization. Frankly, it ain’t cheap. Depending on your desired level of investment and the number of users you’ll need, it can run the tab up quickly. Additionally, user management in Tableau itself isn’t an issue, but deployment presents its challenges. Other options on the market are much easier to introduce users to (here’s your login, go to this URL and boom, you’re good to go) whereas Tableau requires more configuration. This is dependent on which Tableau version you utilize, but there are efforts involved in scaling the platform.

The future of Big Data visualisation and processing

5,0 6 anni fa

Commenti: It took me some time to understand the scope and approach of Tableau. During this time i was confused and sometimes frustrated as It was hard to get static reports out of tableau. Once however I understood the magic behind it (well actually it wasn't Tableaus fault, but just me being stubborn) a whole new world of analyzing data opened up. A Magnificent, splendid, dynamic and playful way of getting answers from data and a completely new way of thinking questions to ask from my data. If you do not have to create static reports which you want to mail daily to a bunch of people but want to explre the secrets your data holds This is THE tool. Definite recommendation.

Aspetti positivi:

Tableau is centered around you as a user asking questions to your data. It is as simple as that and it works in ways not imagined before. Via graphical user antierface and drag and drop you combine aspects of your data and visualize relations. The coolest thing is that Tableau supports you without pushing or distracting. The process is emergent and makes it possible to walk the line from coherence to causality and have fun along the way. The End results look great and can be reformated by a couple of clicks in order to shift perspective or look from a different angle or with a different point of interest towards your findings. Tableu picks you up where you are and you can run it as SAAS or on premise, depending on your preferences. Also the API is simple and powerful, making the integration as a dedicated reporting and statistcs module, or more precise data visualisation playground to your existing product easy and convenient. By doing so you can add tableaus product-versatility, ease of use and beauty to a product and participate from its user friendly and open aproach to data analysis.

Aspetti negativi:

The licensing was a bit of a hassle as we started in the early days of tableau. Also Sales were very eager and pretty actively tried to support us. This never was a bad thing, just a bit too much. Also Tableau introduced support for document based databases rather later than earlier so we had a slight wait there. Then again, every time the did include a feature it was just bug free and worked like a charm so this was allright as well. Two things are especially important when evaluating Tableau, from my point of view: The data you whish to process with it must adhere to a minimal standard (or you will have to do a lot of conversion before you can enjoy it within tableau). So older datasources might become somewhat bothersome or at least require a preprocessing step. Most important is that you understand what tableau is for: You will have a great time when dynamically and actively exploring data, even rapidly changing data or real time streams. If you use a tool for creating static reports you waste the potential of this great piece of human engineering and might run into issues.

Tableau Recommendation

5,0 3 anni fa

Commenti: Tableau allows complex data to be simplified by visualizing it. We can take a complicated digital marketing budget daily task and implement it via Tableau user dashboards etc. This will then open possibilities to automating specific processes that are a part of the whole task. Another point in my experience - we can totally use Tableau to create a dashboard that allows non-technical stakeholders to understand technical data via dashboards.

Aspetti positivi:

- Amazing data visualization capabilities - Tableau can comfortably handle large amounts of data. A million rows of data can be visualized without affecting the overall performance of the dashboard - Dashboards can be built interactively using the drag & drop function - It runs effectively and efficiently across different devices & -

Aspetti negativi:

- There seems to be no schedule or automatic refresh functionality - There is no custom visual import option available - Scaling may cause potential high costs if the organization is huge

Tableau Through My Eyes

5,0 anno scorso

Aspetti positivi:

The wide range of chart types, maps, and graphs allows me to present complex information in a visually appealing and understandable way. The intuitive drag-and-drop interface empowers me to create stunning visualizations without needing to rely on extensive coding or technical expertise. One standout feature of Tableau is its interactive dashboards. I can consolidate multiple visualizations and key metrics into a single, dynamic view. Being able to explore and interact with the data directly on the dashboard, applying filters, and drilling down into specific details, provides me with a comprehensive understanding of trends and patterns. The level of interactivity offered by Tableau truly engages my curiosity and helps me uncover insights that would have otherwise remained hidden.

Aspetti negativi:

While Tableau offers an array of powerful features, there is a slight learning curve involved in mastering its advanced functionalities. As a beginner, I found myself needing to invest time in understanding the intricacies of certain features, such as statistical analysis and forecasting. Although Tableau provides resources and a supportive community, a more user-friendly onboarding experience or interactive tutorials would have been beneficial.

On the fly BI tool with rich visualizations and Dashboard features

4,0 5 anni fa

Commenti: We used Tableau for Visualization BI apart from having Business Objects for reporting. We have created a story for a given subject with all the related information to present to the user. It gives a quick glance on what is happening on the sales of drug for a pharma company that I worked. Migration from non-prod to prod is very easy (unlike other BI tools). Cost of the project reduces a lot with Tableau for BI projects

Aspetti positivi:

Tableau has changed the BI world a lot. It has brought in a software, using with business user can create dashboard & reports on the fly and can check what is there inside. It allows the user to read through the data and derive the insights without much technical analysis. First it can connect to any database (I know about 44 database it connects) and you can set the data, slice the data needed for current analysis and then you can do quick reporting. It provide multiple features, like different charts, graphs and tables and mathematical and statistical functions for analysis. Once you have create multiple visuals you can put them onto one dashboard or multiple dashboards into a story and present the same to business

Aspetti negativi:

Even though it has rich features but it can support the Enterprise BI needs like business object or Cognos does. It does not provide all the feature for E L T (extraction, load and transform) which requires complex transactions. As data gets huge the graphs and charts become unreadable. also, this software is more useful to the business user for personal purpose than company wide reporting etc. The administration part of it needs a lot.

Tableau Dashboards

5,0 2 anni fa

Commenti: It is a fantastic tool and helped every sales rep tremendously however, it is the one tool where if you want the execution needed, I would recommend working with a third party vendor for help.

Aspetti positivi:

Tableau is used for personal dashboards for each sales rep. It is the best way to capture all their macroeconomic statistics. All the clients, facilities, states they have visited and simultaneously, showing them all their results. Their net sales and % to quota. Essentially, the sales rep can view all their information in 1 dashboard and also share any information with other clients based on their historical performance.

Aspetti negativi:

The biggest downside with Tableau is that once you create the dashboards and want to make minimal changes, such as add a new user to the total dashboard, many changes need to be done, it is not simple to completely update the data webs behind the dashboards so that they update properly.

Best Visualization tool in the market

5,0 2 anni fa

Commenti: Overall Tableau has made our daily to daily work much easier be it data collection from different sources or creating custom reports and dashboards or analyzing large set of data to gain impactful insights.

Aspetti positivi:

It has amazing data visualization capabilities. Working for an organization where mostly reporting and visualization done on excel, When Tableau was introduced to our team and has been so much beneficial for us. You can create a scintillating and self-explanatory dashboard using this which is easily understandable by higher management even if they don't have any technical knowledge. Tableau can handle a large number of datasets also very easily and that dataset can be easily visualized without facing any performance issue. One thing which I like the most about tableau is report scheduling where your reports can be updated automatically every day. Another thing which i love about tableau is that multiple and different kind of data sources can be easily connected at one place.

Aspetti negativi:

Till now nothing that hinders me while working on this tool as its meeting all my expectations.

A great dashboard(-ing) tool

4,0 3 anni fa

Commenti: I have been using Tableau for more than 2 years now. The software offers a lot of flexibility with producing visuals.

Aspetti positivi:

Tableau has many great features but my favorite is its intuitive working which enables first-time users to quickly learn its basic functionality and gradually learn some tricks along the way. Tableau's connectivity to Excel, sharepoint, APIs, google sheets, text/csv files, databases - SQL, oracle etc covers pretty much all bases for my organisation's needs. I have also been using Tableau Prep from the suite to scrub data while recording each step along the way which is a great feature that helps with reproducibility. The Tableau online community has been a big help troubleshooting my issues and providing inspiration through showcased works.

Aspetti negativi:

Some of the API connections (e.g. with Safety culture) are not as seamless when compared to the competitor product - Microsoft PBI.

A flexible and powerful tool

5,0 6 anni fa

Commenti: I am an analytics consultant and used to work mostly with SAP BW (Business Objects, Business Explorer, etc), Lumira, and Qlik Sense. My first contact with Tableau was very good, I've learned many things in a few days, it's very easy to use and also very powerful. I'm happy in working with this project because Tableau makes my experience much better, I'm liking it.

Aspetti positivi:

The easiness on creating simple reports don't obfuscate its power on creating complex dashboards. If you want to create a simple bar graph that shows your sales amount, you can do it easily and quickly, but it doesn't take out the tools and mechanisms that allows advanced users and consultants to do more, like creating complex non-existent (not ready-available in the tool, but possible) charts like exploded bar charts. It supports formulas and also have a very good engine for it, as you can define one and reference it by its name wherever you need. As an analytics consultant, I've seen many other reporting tools, like Qlik View (and Sense), Power BI, SAP Lumira and so on, so I can tell that Tableau is a major competitor in segment.

Aspetti negativi:

A common problem that takes place inside large companies lies on the difference between how we think Tableau looks for data and how it actually does. At one of the cases we have SAP Hana as a database with its views as data source and Tableau as the reporting tool. Some of our dashboards have been stated as "slow", but we figured out that the problem was not on the columns that was available and being used by Tableau, but in the other columns. The Tableau doesn't ever create the same SQL as we are expecting for a situation, it has a complex way to determine the better SQL for the best user experience. This slowness is known wherever you ask for "Tableau main problems". So the problem was not entirely on Tableau, but in the way we created the views. This is a very light con that has the main purpose to aware software buyers instead of saying "don't buy". In short, the slowness may lie on data source instead of Tableau's engine. You should care about how data is delivered to it.
