Illustrate available options using a BI Picture Book
A BI Picture Book is a structured collection of “pictures” aka screenshots of features illustrating one or multiple products. It describes and illustrates the available options in a compact and easy to handle manual. It should help the user to identify what options they have in a given BI front end application.
Referring to scenario A and B above, in an ideal world one would create a BI Picture Book during the initial tool selection process (scenario B). In this context, the BI Picture Book helps to illustrate the available features of the different tools under consideration. Some (or all) of these tools will become “strategic” and therefore the preferred tools to be used during subsequent BI projects. In the same way, the corresponding parts of the original BI Picture Book will also be included in the “daily business” BI Picture Book, which only contains the available options regarding the strategic tool set.
One main characteristic of a BI Picture Book is that we compare feature (or requirement) categories one after another and not a tool (with all its different features) after another tool. This helps to clarify specific differences between the tools for each category.
Based on the previously described structure, the BI Picture Book should contain notes which highlight unique features of one tool compared to the rest of available (or evaluated) tools, e.g. a specific chart type which is only available in one tool. On the other hand, one should highlight limitations regarding specific features that are initially “not obvious”, e.g. in cases where the color palette of charts cannot be customized. Another example is to specifically highlight a tool which does not contain an Excel export (because end users might assume that there is an Excel export for every imaginable BI tool, so that they think they do not have to specify this).
How to build a BI Picture Book
Building a BI Picture Book is primarily about taking screenshots and arranging them in a structured manner, e.g. following the seven feature categories introduced above. As with every other project, certain points need to be planned and clarified before you start:
- What is the primary purpose of the BI Picture Book? This refers to either scenario A) requirements engineering or scenario B), creating a front end tool strategy.
- Which BI tool vendors are to be taken into consideration? Which concrete tools of these vendors are to be integrated into the BI Picture Book? For scenario A) this is defined by the available strategically defined BI toolset. For scenario B) it depends on the procedure for evaluating and selecting tools for your front end tool strategy.
- Once you know which tools you want to take screenshots of you need to define which software version to use. Depending on the release cycle of the BI vendor, the software version can make quite a difference regarding available features. Therefore a BI Picture Book is mostly specific to a certain version.
- For cars, there are tuning shops which provide extra features not offered by the car manufacturer. Similarly, in the BI world, there are many add-on providers who extend the available features of BI products. If such add-ons are already in place, it is important to include their features in the BI Picture Book. Nevertheless, one shouldn’t forget to label features from add-on products specifically as they might be charged additionally.
- Do not show options which are not applicable in practice, e.g. system wide customizations on a multi-tenant BI platform. An example is customizing the look and feel of the BI portal by modifying the portal’s CSS style sheet. Although, in theory, this option might exist, depending on your organizational and technical setup, to changing the style sheet might not be allowed because many other stakeholders would be affected.
After having answered these questions, you can start: Take whatever screen capture program you like and start taking the screenshots. Use either a tool like Microsoft Powerpoint or Word to collect and layout the screenshot in a meaningful way. Keep an eye on the point that the BI Picture Books’ main characteristic is about comparing a specific feature over multiple tools. Therefore, put the screenshots of a given feature for multiple tools side by side on the same page or slide.
The subsequent paragraphs will illustrate how a concrete BI Picture Book might look. Screenshots are taken from various SAP Business Intelligence front end tools.
1. Content Options
Content options are difficult to illustrate using screenshots regarding scenario A). For scenario B) we can, for example, compare the different available data connectivity options:
2. Navigation & Selection Options
For navigation options outside of information, products typically screenshots of a BI portal are to be taken. This can be either based on a vendor specific portal or your company’s intranet site (or both if end users have a choice and need to decide which one to use).
On the other hand, a tool provides navigation and selection features inside information products. We usually take screenshots for at least the following elements:
- Parameter & Prompts
- Input Controls
- Groups / Hierarchy View and Navigation
- Drill Down features
Some of these elements are illustrated as follows:
The drill-down example, in particular, shows that it is not enough for an end user to simply specify “we need drill-down functionality” as a requirement. End users need to specify requirements in alignment with the different options of drill-down available.
3. Layout Options
We suggest taking screenshots for the following elements:
- Cross tables
- Conditional formatting
Make sure you list all important features and highlight the unique ones as well as limitations that are not obvious. This helps end users to compare the different options. In some cases, it is important to shed more light on the settings of features such as charts. By way of example, specify if it is possible to change the colors of a pie chart?
4. Functional Options
Next up are functional options, for example export. It is quite simple to find the available options and therefore it is easy for end users to choose from the existing options. It is useless, for example, if you let someone define that he wants a PowerPoint export from a front end tool, if it does not exist. Of course this would be nice, but it is simply not part of the catalog.
Another category of functions is printing. Usually it is not precise enough if an end user specifies he needs to print a document. Giving them a picture book, they can easily find out the available printing options. The BI Picture Book should clarify points such as if you can mix landscape and portrait page mode or choose «Fit to page». Below is our list of typical functions which could be integrated into the BI Picture Book:
- Export formats
- Printing options
- MS Office Integration
- Commentary features
- Multi-language support
- Search options
5. Delivery Options
An up-to-date topic which falls into the category of delivery options is mobile-device compatibility. This is becoming increasingly important at a time when all information should be available independent of the end users geographical location. Depending on the BI vendor and the BI tool itself, mobile devices support can differ considerably. Some serve the information products 1:1 to mobile devices. Others transform existing information products into specific mobile versions, which might have quite a different look and feel compared to the original information product.
6. Security Options
As with content options, it is somehow difficult to visualize security options using screenshots in a meaningful way. Try to focus on the comparison aspect between different tools and highlight unique features and limitations that are not obvious. The following example illustrates the available access rights for two different tools. One tool can simply restrict the export functionality in general, whereas the other tool can control the different export formats.
7. Qualitative Options
It is hard to illustrate this category using screenshots. Yet, as indicated in a previous paragraph, you can try to find other illustrations to guide your end users in specifying qualitative requirements.
As with my other blog posts this article doesn’t aim to be a complete list of something. A BI Picture Book is neither the only way to define BI specific requirements nor is it enought to define a complete BI front end tool strategy. It shows you a particular idea and it is up to you to apply it in your organization in combination with other appropriate methods.
