よりよい意思決定のためのツールを開発

2013年5月28日

ポーツマス大学の研究者によって生み出された新しい意思決定ツールが、ビジネスへの大きな可能性を秘めているとして、大々的に賞賛されました。

Alessio Ishizaka博士, Philippe Nemery博士らが、the Outstanding Paper Award for the Literati Network Awards for Excellence 2013を受賞しました。

博士らによるファイナンス、環境、マーケティング、医療診断等あらゆるセクターの意志決定者が用いる数々のメソッドを分類・分析する研究は、複雑な意思決定の結果を向上させる潜在的な能力を有しているといわれています。この研究成果は、the Journal of Modelling Managementの最新版に発表されました。

Dr Ishizaka is an expert in decision analysis and Dr Nemery is a mathematician.

In their study, they examined 20 small and medium sized businesses in France to assess the quality of their decisions and the success of each business.

They found existing decision-making tools, widely used by businesses, give results which are too broad to be meaningful and, as a result, are unable to help a decision maker make radical improvements.

Instead, the researchers developed and tested a finer detailed and visually graphic model, which they say will make it much easier for businesses learn and grow.

Dr Ishizaka said: “Companies prosper or fail as a direct result of decisions taken by managers or stakeholders, so it’s vital the way they make decisions is examined.

“Several decision-making tools exist but they provide raw, quantitative data rather than richer qualitative results which give decision makers true insight into multi-criteria problems.”

The new model allows decision makers to compare different actions and outcomes on a visual scale.

When the model was tested it gave a huge degree of detail about each companies’ strengths and weaknesses, which no previous models had been able to do.

Dr Ishizaka said: “This new model allows us to understand each company compared to its competitors. We could see, for example, that a company was good at project management but weak at human resource management, while a second was good at knowledge management but poor at product development, giving a much fuller measure of each companies’ capabilities.

“Existing models give flatter results, for example, ranking companies from best to worst, even if all the companies are performing poorly, and with no detail on which aspects were needing attention and which were being managed well.

“In our case study we could see immediately, once analysis was done, that even the best-ranked company still had room for improvement. That sort of detailed information is of significant help to anyone whose job is to make the best decisions, whether they are in finance, medicine or any other sector.”

The French co-authors of the research have since been awarded a grant of nearly 500,000 Euros from the French trade union, Union des Industries et Métiers de la Métallurgie, to develop the tool online to allow all businesses to use the tool to evaluate themselves. Dr Ishizaka will be supervising the development of the website and analysing the collected data.
