Full-Cycle Interior Design: Time and Quality Management at All Project Stages

The study analyzes the main principles and mechanisms of managing time resources and quality characteristics of comprehensive interior design projects — from the concept generation stage to the actual handover of the finished facility. The relevance of the topic is determined by the rapid expansion of the global design services market with a projected volume of 142.41 billion USD by 2025 and the accompanying complication of requirements for execution times and levels of execution accuracy. The aim of the work is to create and substantiate an integrated project management model that integrates advanced methodological approaches and digital technologies to optimize time and quality metrics. The methodological basis of the study relies on a systematic analysis of recent scientific publications, examination of practical cases, and processing of statistical data. Business process modeling was applied as a key tool, enabling the identification of bottlenecks and the development of mechanisms to overcome them. The resulting project management model proposes a combination of adaptive Agile techniques during the creative development stages, Lean manufacturing principles in organizational support and implementation, as well as end-to-end implementation of BIM technologies to ensure the integrity of the information flow and preventive quality control. The scientific novelty of the work lies in the formulation of a hybrid approach finely tuned to the characteristics of the full cycle of design projects. The practical significance of the results is manifested in the applicability of the proposed model by design studio managers, project leaders in the construction industry, and researchers in the fields of architecture and interior design.
