Introduction
Operational planning, situated at the lowest managerial level, serves as a crucial aspect of organizational management, delineating specific procedures and processes essential for the efficient execution of day-to-day tasks (Biondi & Russo, 2022).Entrusted to managers with a deep understanding of current issues and daily responsibilities, operational planning entails identifying and promptly executing specific activities with the available resources, deriving from a one-year process rooted in tactical planning and aligned with the organization's overarching strategy (Moreno-Carmona et al., 2020).This planning level operates continuously at the business unit level, embodying a more tangible and specific approach (Iheanachor, 2022;Richard et al., 2019;Howes, 2018).The convergence of operational planning with the work planning for technological units within an organization underscores its significance in shaping the trajectory of business operations.
The effectiveness of operational production planning hinges on the careful selection of production types, aligning with the most advantageous strategy for crafting the operational plan (Vigfússon et al., 2021;Yoshikuni & Albertin, 2020;Parnell & Brady, 2019).The intricacies of operational planning instruments play a pivotal role in setting and monitoring performance standards, emphasizing the need for precision in their application.A comprehensive timetable becomes indispensable for the success of operational production planning, emphasizing the need for meticulous scheduling in the pursuit of optimal outcomes (Nwachukwu & Vu, 2020;Beekun & De Carvalho, 2021;Khan et al., 2019).
Amidst the ongoing debate surrounding the utility and significance of operational planning in the contemporary business environment (Nugraha et al., 2022), numerous challenges underscore the complex nature of this managerial facet.Challenges such as time and financial constraints, uncertainty about the future, financial management intricacies, performance monitoring intricacies, regulatory compliance, competency alignment, and technology integration pose formidable hurdles.The repercussions of inadequately defined implementation procedures are far-reaching, impeding the operational manager's ability to successfully execute the overarching strategy, fostering confusion and ambiguity.
In the context of mobile service providers in Nigeria, operational planning has played a pivotal role in business expansion, talent acquisition, and the establishment of new branches.However, despite the extensive use of operational planning, the industry faces stagnation, marked by a limited number of companies and network failures (Elsawy, 2022).This study delves into the core objective of unraveling the impact of operational planning on the performance of mobile service providers in Nigeria, with a specific focus on examining its effect on the industry's growth.The subsequent sections will illuminate the nuances of operational planning in the Nigerian mobile service provider landscape, exploring the intricacies that shape its efficacy and influence on organizational performance.

The Concept of Operational Strategic
An operational strategic plan serves as a detailed blueprint outlining the major initiatives and goals a company aims to pursue over a specific timeframe, typi-Journal of Human Resource and Sustainability Studies cally a year (Eric, 2022).This plan, intricately linked to the organization's overall strategic objectives, is often associated with financial agreements (Bhasin, 2019).
It is a specialized strategy that precisely articulates how a particular team or department contributes to the realization of broader organizational goals, encompassing regular duties crucial for the smooth operation of the firm.Effective operational planning ensures clarity of individual responsibilities for both management and employees, fostering success by establishing a clear path to achieving business and operational objectives (Bhasin, 2019;Michael, 2022).
Operational planning is a dynamic and continuous process aimed at developing, expanding, and enhancing the day-to-day operations of a business entity (Kallio et al., 2017).This strategic document, known as an operational plan, delineates the detailed planning required for daily activities and procedures essential for managing a successful business (Howes, 2018).It encompasses the tasks assigned to various departments, including finance, marketing, and recruitment, aligning their efforts to meet the business's aims and objectives.Operational planning is integral to strategic planning, serving as the primary component by focusing on gaining a competitive advantage through cost-cutting and generating new income.By identifying areas that require modification and addressing revenue shortfalls or losses, an operational strategy assists a company in adapting to the evolving business landscape (Michael, 2022).

The Concept of Performance
Various organizations employ diverse criteria to assess their performance, with metrics such as growth, expansion, survival, personnel count, and capital employed being common benchmarks.Performance, as articulated by Gartenberg et al. (2019), encapsulates the financial well-being of an organization and serves as an indicator of its overall operational health.Operational performance, highlighted by Siahaan et al. (2023), is a specific facet that evaluates an organization's efficiency in creating and delivering products to customers, emphasizing quality and timeliness as key factors.Richard et al. (2019) elucidate that corporate performance encompasses financial metrics like profit growth, return on assets, and return on investment, offering a holistic view of a company's outcomes.
Performance measurement is multifaceted and involves diverse criteria, with growth being a pivotal aspect.The expansion, survival, and competitiveness of small businesses hinge on their ability to exhibit growth, often manifested in increased raw material consumption for goods and services production (Opusunju et al., 2019).Akyuz & Opusunju (2021) propose consumer growth, job creation, and business size as proxies for assessing growth.Onyema (2019) emphasizes the favorable dimensions of growth, encompassing employee count, sales, turnover, product and customer relationship quality, all of which contribute to increased assets and profits.Growth, as noted by Elumeh et al. (2016), extends beyond tangible aspects to include knowledge, human experience, efficiency, and quality, occasionally measured in terms of turnover and profit.Mukiibi & Magunda (2019) investigated the relationship between strategic planning and firm performance in selected law firms in Kampala, Uganda.It considered other factors such as networks with the political and technical bureaucracy, behavior of decision makers, firm leadership and operational tactics, networks in the social sphere, and international connections that drive the performance of law firms.The findings revealed a high extent of strategic planning and high firm performance among the studied law firms.There was a positive and significant relationship between strategic planning and firm performance.

Empirical Studies
Equally, Awino et al. (2022) studied the impact of strategic planning on firm performance in Kenya.They used data from 44 commercial banks, focusing on seven dimensions of planning: operational planning, external orientation, functional integration, competitive planning, use of planning techniques, creativity, and focus on control.The study found a positive relationship between strategic planning, planning outcomes, and firm performance, suggesting that effective and focused strategic planning leads to positive changes in firm performance.In the same vein, Ojha et al. (2020) conducted a study on US-based SMEs, examining the relationship between dynamic strategic planning and financial performance.The results showed a negative and non-significant association between operational capabilities and financial performance.Also, Reza et al. (2022) looked at how the application of operational planning affected the performance of universities and the healthcare system.They analyzed seven important performance metrics for public health, education, research, nursing, treatment, food and drug policy, and student affairs before and after OP adoption.Findings of the study established a positive and statistically significant relationship between operational planning and performance of the identified proxies.
Furthermore, the performance of small firms is studied by Larry and Joseph (2023) in relation to operational and strategic planning.All community banks operating in the mountain states of Arizona, Idaho, Montana, Nevada, Utah, and Wyoming made up the study's target population.170 tiny, independently operated banks were found using the community banks industry classification.The findings indicate that there were substantial differences in the inventory, marketing, and financial planning activities between the groups, with successful merchants being more likely to perform these activities than unsuccessful retailers.There were no variations in personnel planning between the groups.The study's ramifications for university researchers and small company professionals are examined.
While existing literature has explored the relationship between strategic planning and firm performance in various contexts, there appears to be a noticeable gap concerning the specific impact of operational planning on the performance of mobile service providers in Nigeria.Studies by Mukiibi & Magunda (2019) in law firms in Uganda, Awino et al. (2022) in Kenyan commercial banks, Ojha et al. (2020) in US-based SMEs, and Reza et al. (2022) in the education and health-Journal of Human Resource and Sustainability Studies care sectors have primarily focused on strategic planning.However, the identified literature does not explicitly address the effectiveness and influence of operational planning on the performance of mobile service providers in the Nigerian context.Additionally, while Larry and Joseph's (2023) study on community banks in mountain states provides insights into operational and strategic planning's impact on small firm performance, it does not specifically address the unique operational challenges and planning considerations within the mobile service provider industry in Nigeria.Therefore, there is a notable gap in the literature regarding the tailored examination of operational planning and its implications on the performance dynamics of mobile service providers in the Nigerian business landscape.
