There is no need of any specialist to make it and analyze it. The bubble diagram or bubble chart (BC) is a graphing technique used in project portfolio management to making decision, especially to display balance in new product project portfolios. One of the examples of such tools is the matrix diagram. Different methods as the financial methods, strategic methods and scoring model. A Program Evaluation Review Technique (PERT) chart is a project management tool that graphs a project's timeline according to the individual tasks. Bubble sort is one of the easiest sorting techniques in programming and it is very simple to implement. Dataset Properties¶. A bubble chart (aka bubble plot) is an extension of the scatter plot used to look at relationships between three numeric variables. To create a bubble chart in Excel with its built-in function – Bubble, please follow the steps one by one. Bubble charts allow us to visualize three different measures at the same time. Similar to a bubble chart in which the bubbles are tightly packed rather than spread over a grid xViz packed bubble visualization, we just need one category and a measure to use the Packed bubble as Categories define the individual bubbles, and measures represent the size and color of … [3]. However it’s important to clarify the Bubble chart cannot be used alone for decision making since does not give enough information , instead should be combined with other tools. It thereby scores below elements such as “financial method” and “business strategy”, which 77 % and 65 %, respectively, of businesses use and 40 % and 27 % consider their dominant method.

Dla niezorientowanych, bubble chart zawiera bąble reprezentujące projekty. A bubble chart requires at least three variables (columns) of data: one showing the size of the bubbles and two others showing the horizontal and vertical position of the points. The second tutorial of the series covered line and bar charts.The third tutorial discussed radar and polar area charts.In this tutorial, you will learn how to use Chart.js to create pie, doughnut, and bubble charts. Presenting projects that are scored based on different criteria or using different models within one Bubble Diagram will reduce the comparability of the projects without one necessarily being able to see this from the diagram. By employing different colors to sort data into categories (or even shaded hues across a gradient to represent numbers), the bubble plot reveals its extremely useful nature: On this graph, the projects are displayed as surfaces, where the size, shape, colour etc. How is possible to check the amount of resources spent on development of new products versus product renewals (improvements and replacements), or product extensions, or product maintenance?

These projects are the not-wanted projects that exist in almost every company. Since this then is considered to account for the financial probability of success, the secondary axis displays only a measure of the technical probability of success. You interpret the bubble-chart format as follows: The bubble in the center represents your entire project (in this case, Report). Risk-Reward Bubble Diagrams in Project Portfolio Prioritization, Variants of the classical Risk-Reward Bubble Diagram. For this reason they should be reduced in number and dimension as much as possible.

Analyzing the above bubble chart, Risk 001, Risk 002, and Risk 004 will be of higher priority because they have high manageability, high detectability, and high impact. Bubble chart is a little different from pie and bar charts because it represents three dimensional data. These ellipses indicate the uncertainty on each of the axis parameters. In almost every organisation, there is a limited amount of accessible resources meaning that these should preferably be distributed on the Pearls and Oysters/Bread-and-Butter projects. z-axis which represents the size of the bubble. This tool is very similar to the Power/Interest or Power/Influence grids. To achieve this success, many different tools and methods are used. Moving to the right, in the Oysters zone, there are three bubbles of different dimension; Overall it can be noticed the presence of good investments for the resources and a sufficient number of projects, which mean good possibility of innovation in the future.

Also here is possible to use a histogram where the inflows and the outflows are showed for every project. Here is an Excel bubble chart made with a simple three-column data set. the different and additional axes possibilities, might make the use of a Risk-Reward Bubble Diagram preferable over the BCG-matrix for, amongst others, new product projects.
