Traditional performance assessments relied only on sales, lacking other efficiency measures. This research proposes a mathematical function to combine diverse Key Performance Indicators (KPIs) to better evaluate team effectiveness. Additionally, it aims to optimize the sales territory assignment, improving resource allocation across Canada\u2019s expansive, sparsely populated regions. Customer segmentation was conducted using the RFM model, classifying clients into Low-, Mid-, and High-Value groups based on purchasing behavior. For incorporating multiple KPIs in the evaluation of commercial teams\u2019 performance, the Analytic Hierarchy Process (AHP) was used. Sectorization was modeled as a linear programming problem to minimize travel distances while ensuring compact sales territories. Constraints included balancing sales opportunities and customer types across assigned territories. As a result, the proposed optimization model significantly improves operational efficiency through better-balanced sales territories and reduced travel. Improved sectorization enhances market penetration and customer coverage, which is expected to lead to increased sales and support the company\u2019s growth objectives. The mathematical models developed in this study allowed for a deeper understanding of the performance and provided management with tools to refine sales strategies and allocate resources more effectively. The article ends with a discussion on the possibility of ChatGPT being used to replace a mathematician in performing this analysis for the company. It was observed that ChatGPT (version GPT-4o) provided an extremely incomplete solution, evaluating the commercial teams solely based on profit and sales and not addressing the sectorization problem at hand.<\/jats:p>","DOI":"10.3390\/math13182940","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T10:50:04Z","timestamp":1757587804000},"page":"2940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimizing Commercial Teams and Territory Design Using a Mathematical Model Based on Clients\u2019 Values: A Case Study in Canada"],"prefix":"10.3390","volume":"13","author":[{"given":"Ana Miguel","family":"Carvalho","sequence":"first","affiliation":[{"name":"Nors Group, S.A., 4149-010 Porto, Portugal"},{"name":"Banco Portugu\u00eas de Investimento, 1050-094 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4833-470X","authenticated-orcid":false,"given":"Cristina","family":"Lopes","sequence":"additional","affiliation":[{"name":"LEMA, ISEP, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4249-015 Porto, Portugal"},{"name":"CEOS.PP, ISCAP, Polytechnic of Porto, rua Jaime Lopes Amorim, 4465-004 S\u00e3o Mamede de Infesta, Portugal"}]},{"given":"Manuel","family":"Cruz","sequence":"additional","affiliation":[{"name":"LEMA, ISEP, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4249-015 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2760-7756","authenticated-orcid":false,"given":"Jorge","family":"Santos","sequence":"additional","affiliation":[{"name":"LEMA, ISEP, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4249-015 Porto, Portugal"}]},{"given":"Sandra","family":"Ramos","sequence":"additional","affiliation":[{"name":"LEMA, ISEP, Polytechnic of Porto, rua Dr. Ant\u00f3nio Bernardino de Almeida, 4249-015 Porto, Portugal"}]},{"given":"Filipa","family":"Vieira","sequence":"additional","affiliation":[{"name":"Nors Group, S.A., 4149-010 Porto, Portugal"}]},{"given":"Pedro","family":"Louro","sequence":"additional","affiliation":[{"name":"Nors Group, S.A., 4149-010 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,11]]},"reference":[{"key":"ref_1","unstructured":"Zuse Institute Berlin (2024, May 13).
