Requirements Definition and Management Practice to Improve Project Outcomes / Reikalavimų Apibrėžimas Ir Vadyba Gerinant Projekto Rezultatus

Abstract

Poor project requirements definition and management (RDM) is one of the major causes of project failure. However, many organizations do not adequately manage a project's requirements leading to a poor design basis. Thus, quality of requirements is critical to the success of any construction project. The primary purpose of this research was to investigate the mediating effect of requirements quality on the relationship between RDM practice and project performance. The second objective was to determine whether the impact of RDM practice on project performance was moderated by project characteristics. A three-phase approach was employed to investigate construction projects in the Taiwanese building industry. The testing supports a role for requirements quality as a partial mediator in the relationship between RDM practice and project performance. The findings also indicate that project characteristics have a moderating effect on the relationship between requirements quality and overall project performance. Santrauka Prastai apibrėžti ir valdomi projekto reikalavimai – viena iš pagrindinių projekto nesėkmės priežasčių. Tačiau daug organizacijų neskiria pakankamai dėmesio projekto reikalavimų valdymui, todėl sukuriamas prastas projektavimo pagrindas. Taigi kokybės reikalavimai yra esminis sėkmės garantas bet kuriame statybų projekte. Pagrindinis šio tyrimo tikslas – išnagrinėti, kaip reikalavimų kokybė veikia jų apibrėžimo ir valdymo ryšį su projekto efektyvumu. Antrasis tikslas – nustatyti, ar projekto savybės mažina reikalavimų apibrėžimo ir valdymo poveikį projekto efektyvumui. Pritaikius trijų etapų metodą, išnagrinėti statybų projektai Taivano statybų sektoriuje. Bandymai patvirtino, kad reikalavimų kokybė iš dalies keičia jų apibrėžimo ir valdymo ryšį su projekto efektyvumu. Išvados taip pat rodo, kad projekto savybės riboja reikalavimų kokybės bendram projekto efektyvumui poveikį.

“…The failure to define and manage project requirements, or the lack of quality of requirements, is one of the main causes of project failure. However, not all organizations successfully manage project requirements and follow up on requirements, addressing potential risks in a timely manner, resulting in errors that lead to project failures (Yang et al, 2010). According to a study by Coventry T., published at the Project Management Institute (PMI) conference on 11.05.2015, the project requirements management process can be divided into the following stages: 1.…”

A Comprehensive Framework for Evaluating Key Project Requirements

“…Thus, requirements definition is often cited as one of the most important, but difficilt, phases of a project (Brooks 1987). The results of previous studies indicated a correlation between requirements definition effort and project performance (Damian, Chisan 2006;Procaccino et al 2002;Brooks 1987;Kauppinen et al 2004;Herbsleb, Goldenson 1996;Huang, Hsueh 2010;Radujković et al 2010;Toor, Ogunlana 2010;Yang et al 2011).…”

The Project Management Process of Planning and Budgeting in Public Construction Projects

“…A solution to construction projects' schedule and budget escalations is increased pre-project planning and project requirement definition (L.-R. Yang, Chen, & Huang, 2012). Dvir, Raz, and Shenhar (2003) argue increased pre-project planning does not guarantee a successful project outcome, but a lack of pre-project planning will on the other hand guarantee project fail-ure.…”
