―第7章―タイムスタディの明日：業務合理化の分析から業務科学へ

Chapter 7: Tomorrow of Time and Motion Study: From Job Analysis to Science Seeing New Horizon

生産性向上に必須のタイムスタディ

　生産性向上の検討には，タイムスタディによる正確なデータの収集，蓄積，分析と改良実施後の実証評価の繰り返しが必要とされている。

　

経営工学とタイムスタディ

　私の専門は工学である。タイムスタディと最初に出会ったのは今から44年前の1960年，工学部3年時の経営工学の授業である。アメリカのある大学から派遣されていた若い教官によるTaylorの工場経営理論の講義ののち，実習らしきことをやった。

　アメリカのフォード自動車会社や第二次世界大戦中の航空機生産現場などで，生産性を上げるための厳しい実証的な積み重ねの手段としてのタイムスタディは，私にとっては魅力あるものであった。

　Initial mission of time and motion study was to enhance productivity of manufacturing in factory. We have been employing it to job analysis of nursing and medical practice because technique of time and motion study has common points to be applied to both industry and medicine. Computer science such as database technology and statistical analysis have been also applied to support interpretation of time and motion study raw data.

　However, standardization activity to fix terminology, nomenclature and thesaurus in nursing and clinical practice is expected to raise effectiveness of time and motion study. Management of “complexity” which is utilized in the field of information system development must be inspired to time and motion study extension to other applications than mere job analysis.

　We believe that future of time and motion study is very bright since it will be applied to many fields such as home care of aged people and rehabilitation of handicapped people. New horizon of time and motion study will be explored by means of cooperating with other technology such as “structured reporting” which standardizes method of description, filing and communication of findings in diagnostic procedures.

　Time and motion study is understood as scientific approach as an effective tool. Tools have been employed to find new scientific facts and to invent next tools for next scientific activity. Consequently, we want to encourage scientists in the field of nursing and care at large to try and explore time and motion study approach together with other information technology.
