Will Process Mining tool and BI tool be amalgamated?
The answer is yes. The integration has already begun.
In terms of specific developments, a process mining tool called “PAFnow” is available as an add-on for Power BI. Similarly, “MEHRWERK ProcessMining” is offered as an add-on for Qlik.
On the other hand, process mining tools have also been enriching their “dashboard features” in addition to the standard features of process mining, such as “process discovery” which automatically creates a process model from the event log, but this dashboard feature is now close to the level of functionality provided by BI tools.
By the way, both process mining tools and BI tools are the same in that they take in various data related to corporate and organizational management, calculate numbers from various angles, and present the results visually in tables and graphs.
The decisive difference between a process mining tool and a BI tool is in how the calculation results are interpreted and utilized.
Concretely, we can explain as follows.
Calculation results presented by process mining tools
Process mining tools mainly look to performance of activities (processes) that create value = causals. In other words, process mining tools mainly cover Key Performance Indicators (KPIs).
For example, in the case of an insurance company’s claims processing process (from insurance claim to payment), process mining tools can analyze the number of cases for each activity in the process, the total time required for processing (throughput), processing cost, and the number of people in charge, and so on. In addition, the process discovery function can automatically draw a flowchart of business procedures to identify problems such as bottlenecks and inefficient repetitive tasks.
In this way, by analyzing activities that create value, i.e., causal data analysis, it is possible to link them to business process improvement measures to further increase value or reduce costs.
Calculation results presented by BI tools
BI tools mainly look at The size of value (sales, profit, etc.) generated = outcomes. In other words, BI tools cover KGI (Key Goal Indicator).
BI tool basically calculates sales, profit, market share, etc. as a result of corporate activities, and enables multifaceted analysis in various dimensions such as by division, area, and product.
BI tools can make judgments about which business units or areas are producing superior (or inferior) results, but they cannot infer the causes of why results are superior (or inferior). This is because it does not analyze causal data in the first place.
As explained above, to summarize the differences between them, BI tools are like a report book at the end of the term, and they are used to make final evaluations and to set new goals for theKGI in the next term. On the other hand, process mining tools are used to analyze performance in detail during the period and consider how to improve it in order to achieve the goals of KGI.
There is one more difference in the way data is analyzed that has recently emerged.
While BI tools only calculate a snapshot figure of historical data for the entire analysis period, process mining tools are now adding the ability to perform real-time monitoring that sequentially analyzes the data of the cases in the processing.
In order to continuously look back on the status of corporate and organizational operations, and to improve what needs to be improved, ensuring the achievement of goals, it is essential to combine KGI evaluation using BI tools and KPI evaluation using process mining tools.
Currently, more and more companies are using a combination of both tools, but as mentioned at the beginning of this article, the boundary between process mining tools and BI tools is blurring, and in the future, they will be provided as a combined tool.
Process Mining can find 5 problems being called, Muda, Muri, Mura, Mo-re, Miss in the target process.
Quality management as typified by Total Quality Control (TQC) is basically about solving various problems in the execution of business operations and aiming for reform and improvement.
In particular, TQC has been actively used in manufacturing plants, but it has also been applied to a variety of industries and corporate activities, including logistics, service, purchasing and sales. In recent years, the terms TQC and quality control have become less common, but the concepts and methods are universal and still valid today.
In the field of quality control, issues and problems to be improved are grouped into three main categories, which are called “darari” (muda, mura, and muri) or “3Ms”. In addition to these three items, More(mo-re) and Miss -Mistake are added to the 3Ms and called “5Ms”
The 5Ms is, of course, a framework that can be used for process mining analysis based on event logs. In fact, it is a familiar and simple term that provides an excellent starting point for smooth analysis implementation.
So, in this article, we will outline the 5Ms and tell you how they relate to process mining analysis methods.
What is 5M?
First, let’s discuss each of the 5M’s.
Muda can be translated in English as “Inefficient”.
It is a task that takes too long to complete because there are too many steps to accomplish the objective, or because it is too complex, or because it continues to be a formality that does not need to be done in the first place. It is an activity that does not generate much or no value. As these activities are literally “wasteful,” they need to be reduced or eliminated.
Muri is “over-burdened” in English.
Even if the number of cases to be processed is very high, or even if the number of cases is not so high, the number of cases waiting to be processed is rapidly overflowing due to the low number of staff assigned to the case. The result is stagnation and backlog of business. A “bottleneck. The number of projects and processing capacity are not in balance, and an excessive load is being placed on them.
Mura is “inconsistent” in English.
Inconsistency is, simply put, Too many variations in work procedures. If manuals don’t exist, or even if they do exist, they are not being used, leaving a large part of the process to the discretion of the individual, the procedure will vary from person to person. As a result, the throughput varies widely and the quality of the output varies.
In addition, although the basic procedure exists, if there are more cases where the flow of the procedure is complicated due to exceptions to the situation in the field, it is also an inconsistent business process.
Basically, the improvement measures for inconsistency are to reduce exception handling and standardize the process.
More is “omission” in English.
It means intentionally or inadvertently skipping a procedure that should be done. For example, in the inspection process of a production line, it is a customary practice to perform only three types of inspections and then skip them even though there are four types of inspections to be performed. Since some of the inspections that should be done are cut back, this may lead to accidents when the purchaser uses the product or to a recall.
In addition, from a compliance perspective, omission of a specific activity is a clear violation of compliance in a business where the work to be done is strictly regulated.
Since a deviated process that should not be allowed, you need to consider improvement plans such as providing training and education to ensure that the process is implemented, giving a systematic framework to prevent omission, and issuing alerts through continuous monitoring.
The word “miss” is “mistake” in English. To begin with, the Japanese word “mistake” is a diversion from this English word. It also includes the meaning of “error”.
A mistake is a human error, that is, a variety of mistakes made by the staff in charge of a task. Mistakes such as entering the wrong operating procedure or inputting the wrong value cannot be left as-is, but must be corrected by returning to the previous process or redoing the same operation.
The more mistakes are made, the more repetitive and wasteful work is required, and the more steps are required, the more “muri” and “mura” are generated. In other words, the cause of waste, wastefulness and unevenness is “mistakes,” so creating a system that prevents mistakes and RPA automation is an effective improvement measure.
Identification of 5Ms in Process Mining Analysis
Next, we will briefly discuss which of the various analytical functions of process mining analysis should be primarily used to identify the 5Ms, i.e., muda, muri, mura, more and miss.
Muda was an observable occurrence event, which was performing work that did not generate value. This is an issue of reduced efficiency and productivity.
In process mining analysis, after creating an as-is process model (flowchart) from the event log data, we first perform a “frequency analysis” to check how many cases are processed and where in the activities that make up the process and how many cases are flowing to the next process. This is because where there is a high volume of processing, there may be wasted steps lurking.
The next step is to look for process patterns that appear to be performing wasteful activities through “variant analysis,” which allows us to compare process variations. In addition, let’s look for wastage by “rework analysis” that discovers repetitions that are occurring.
Unreasonable workloads and improper procedures can create challenges that cause work to stagnate. Therefore, identifying “muri” means identifying the bottleneck in the process.
Therefore, first of all, we check the areas with a large number of processes with “frequency analysis”. This is because the areas with a large number of processes are not only inefficient, but also tend to be stagnant due to a high load. In addition, the “performance (time) analysis” mainly looks at areas with long waiting times (the time between the previous process and the next process). The part with long waiting time is really a bottleneck. At the same time, “social network analysis” is used to understand the business transfer relationships among the participants in the process in question, and a deep dive is made into which participant in the process is most likely to cause a bottleneck.
The mura is that work procedures vary from person to person, and the lack of standardization makes variation in process quality an issue.
This is the first step in a “variant analysis” to see how many processing patterns there are. The more patterns you have, the more you have, the more various procedures are being performed. We also identify which activities are deviating from the standard by means of “conformance checking”, which is a comparative analysis against the standard process (to be process).
As improvement measures, since standardization is the goal, it is effective to prepare manuals and systematic measures that do not allow multiple procedures.
Because More omits or skips some of the required procedures, it is considered to be a deviation from the standard and a business process with issues of non-compliance.
Therefore, we need to conduct a comparative analysis of the standard process (to be process) and the current process (as is process) reproduced from the event log, or in other words, a “conformance checking”, to identify the deviation.
As for improvement measures, as mentioned earlier, the system should be structured so that the procedure cannot be omitted, and compliance training should be provided to raise the awareness of the person in charge.
Miss(Mistakes) are specifically wrong procedures, careless mistakes, and various other errors that result in rework.
Since it is difficult to determine whether a mistake has been made or not through process mining analysis, we can check whether a large number of repetitions have occurred in activities with a large number of processes or in activities with long processing times by conducting “frequency analysis,” “performance (time) analysis,”“rework analysis,” etc., and finally, we can conclude that The process is verified to see if any mistakes have occurred through interviews with the people in charge on site and by understanding the detailed process at the task level through task mining.
It is difficult to reduce the number of mistakes to zero, but with RPA automation, theoretically, the number of mistakes can be reduced to zero. In addition, if the user interface is difficult to use, or in other words, if the usability is low, mistakes are more likely to occur, so the system will need to be modified to improve usability.
Introduction to Process Mining (17)Outlook for the Future of Process Mining
プロセスマイニングの分析は、2000年代当初からはまずSAPなどのERPシステムが主な対象となりました。したがって具体的には、「購買プロセス（P2P：Procure to Pay)」や、「受注プロセス（O2C: Order to Cash)「」、および経理業務に含まれる「買掛金管理プロセス（Account Payable）」、「売掛金管理プロセス（Account Receivable）」が多く分析されてきました。
近年は分析対象が拡大しつつあります。例えば、販売・マーケティングのプロセス、すなわち集客からの見込客獲得・育成を行うマーケティング活動、および有望見込客に対して行う、受注に至るまでの営業活動を分析する企業が増えつつあります。この背景には、マーケティング活動は、マーケティングオートメーション（MA)と呼ばれる支援ツールが普及し、また営業活動についてはSFA(Sales Force Automation）と呼ばれる支援ツールが普及したことがあります。すなわち、マーケティング、セールスのデジタル化が進んだことによって、プロセスマイニング分析対象となりうるイベントログデータが生成されるようになったわけです。
市場リーダーのCelonisは既に社員数900人を抱え、大型の資金調達にも成功して「ユニコーン」としても認められる存在。そして、リーダーグループの一角を占めるSoftware AGは、「ARIS」のブランドで知られ、「ARIS Process Mining」の販売にも力を入れてきています。Uipath社は、買収したProcessGoldを「UiPath Process Mining」に名称を変え、UiPathが強みを持つRPAを含むトータルソリューションとして提案力を強化しています。
プロセスマイニング市場はまだまだ新しいため、市場全体を把握できるデータや資料がほとんど存在しません。そんな中、イタリアのITコンサルティング会社、「HSPI Management Consulting」が2018年から毎年発行している「Process Mining: A DATABASE OF APPLICATION」は、プロジェクト件数ベースでのプロセスマイニング活用状況を伝えてくれる貴重な調査資料です。
同社では、プロセスマイニングを単なる問題発見ツールとしてだけでなく、実際の業務プロセスが可視化できることで、関係するメンバーが「すごい（Sense of Excitement)」と思ってもらうこと、また、非効率性やボトルネックが一目瞭然となることから「すぐに改善しなければ（Sense of Urgency）」という気持ちを喚起できる仕掛け、すなわちプロセス改善を着手させ（Initiator)、促進する(Katalysator)ことのできる有益なアプローチとして活用しています。
AIG (USA) – Process Wind Tunnel（プロセス風洞）で確実な改善効果を
グローバルに展開する保険会社、AIGでは様々な業務プロセス改善に取り組んでいます。特に、米国AIGの”Data-Driven Process Optimization”と呼ばれる部署では、プロセスマイニング、シミュレーション、BIを組み合わせることで改善成果を積み重ねています。
Data-Driven Process Optimization部署では、プロセス改善の一連の手順を「プロセス風洞（Process Wind Tunnel）」と呼んでいます。自動車や航空機、建築物などの設計においては、風洞に模型を置いて風の流れ等を測定する「風洞実験」を行います。同様に、プロセスの改善にあたって、シミュレーションによる改善成果の予測を行った上で改善施策に展開するという手順を踏んでいるのです。
プロセスマイニング分析結果から、部品補修プロセスの総所要時間（ターンアラウンドタイム、またはスループットと呼ぶ）を長くしている大きなボトルネックは3カ所ありました。すなわち、「検査（Inspection)」、「提案と承認（Proposal and approval）」、「修繕と認証（Repair and certification)」です。
各工程では、大きなユニットの60－80％が処理待ちとなっており、このため6日～12日ほど想定よりも時間が掛かっていました。どれも解決すべきボトルネックではありましたが、どの工程から着手するか、優先順位をつけるために同社では「制約理論（Theory of Constraints）」を適用しました。制約理論は、プロセス改善を目的としてボトルネックの解消に取り組むためのアプローチです。そして、制約理論に基づき、「提案と承認（Proposal and approval）」からボトルネック解消のための施策を開始したのです。
