Estimation et contrôle des coûts

Per-use Cost

Coûts à l'Utilisation : Comprendre le Coût de Chaque Action

Dans le domaine de l'estimation et du contrôle des coûts, il est crucial de comprendre les différents types de coûts pour prendre des décisions éclairées. Un type de coût, souvent négligé, est le coût à l'utilisation. Cet article se penche sur la définition, la signification et des exemples de coûts à l'utilisation dans la gestion de projet et l'allocation des ressources.

Que sont les coûts à l'utilisation ?

Les coûts à l'utilisation, comme leur nom l'indique, sont des dépenses engagées chaque fois qu'une ressource spécifique est utilisée. Contrairement aux coûts fixes, qui restent constants quelle que soit l'utilisation, ou aux coûts variables, qui changent proportionnellement au volume de production, les coûts à l'utilisation sont déclenchés uniquement par l'acte d'utilisation d'une ressource particulière.

Caractéristiques des coûts à l'utilisation :

  • Directement liés à l'utilisation : Le coût est engagé uniquement lorsque la ressource est utilisée, ce qui le lie directement à l'activité ou au projet.
  • Souvent des occurrences uniques : Le coût est généralement engagé une fois par utilisation, sans frais récurrents.
  • Peut varier en fonction de la ressource : Les coûts à l'utilisation peuvent différer en fonction de la ressource spécifique utilisée, de sa capacité et d'autres facteurs.

Exemples de coûts à l'utilisation :

  • Location d'équipement : La location d'une grue pour un projet de construction entraîne un coût à l'utilisation en fonction de la durée de la location.
  • Licences de logiciels : L'utilisation d'un programme logiciel spécifique nécessite souvent une licence ou un abonnement à l'utilisation.
  • Services d'impression : Chaque travail d'impression utilisant une imprimante commerciale entraîne un coût à l'utilisation en fonction du nombre de copies, du type de papier et d'autres facteurs.
  • Frais de péage : L'utilisation d'une route à péage ou d'un pont entraîne un coût à l'utilisation en fonction de la distance parcourue ou de l'itinéraire spécifique.
  • Frais de taxi : Chaque trajet en taxi entraîne un coût à l'utilisation en fonction de la distance parcourue et de la durée du trajet.

Importance de la reconnaissance des coûts à l'utilisation :

  • Estimation précise des coûts : Ne pas tenir compte des coûts à l'utilisation peut conduire à des estimations de coûts imprécises, affectant les budgets et la faisabilité des projets.
  • Optimisation de l'utilisation des ressources : Comprendre les coûts à l'utilisation encourage une allocation efficace des ressources, réduisant les dépenses inutiles en tenant compte du coût par utilisation.
  • Prise de décision éclairée : Connaître le coût à l'utilisation d'une ressource aide à prendre des décisions éclairées concernant son utilisation, en envisageant des alternatives ou en recherchant des options plus économiques.

Conclusion :

Les coûts à l'utilisation sont une composante essentielle de l'estimation et du contrôle des coûts, souvent négligés mais cruciaux pour une planification budgétaire précise et une allocation efficace des ressources. En reconnaissant et en intégrant les coûts à l'utilisation dans la planification des projets et la prise de décision, les organisations peuvent garantir une plus grande transparence des coûts, optimiser l'utilisation des ressources et, finalement, obtenir des résultats de projets plus réussis.

Per-Use Costs Exercise

Scenario:

Your company is planning to host a large conference. You need to choose between two venues:

  • Venue A: Offers a flat rental fee of $5,000 for the entire conference, with an additional per-person catering cost of $50.
  • Venue B: Offers a rental fee of $3,000, with a per-person catering cost of $75.

Task:

Calculate the total cost for each venue if 200 people attend the conference. Determine which venue offers the most cost-effective option for this specific event.

Exercice Correction

**Venue A:** * Rental fee: $5,000 * Catering cost: $50 per person * 200 people = $10,000 * Total cost: $5,000 + $10,000 = $15,000 **Venue B:** * Rental fee: $3,000 * Catering cost: $75 per person * 200 people = $15,000 * Total cost: $3,000 + $15,000 = $18,000 **Conclusion:** Venue A is the most cost-effective option for this conference, despite having a higher flat rental fee, because its per-person catering cost is lower than Venue B.

Techniques

Chapter 1: Techniques for Calculating Per-Use Costs

This chapter explores various techniques for determining per-use costs, enabling accurate cost estimation and informed decision-making.

1.1 Direct Cost Tracking:

The simplest technique involves directly tracking the cost incurred each time a resource is used. This method is effective for resources with easily quantifiable usage, such as:

  • Equipment rental: Tracking the rental fees based on the duration of use.
  • Printing services: Recording the cost of each print job based on the number of copies, paper type, and other factors.
  • Toll fees: Keeping records of tolls paid for specific routes or distances.

1.2 Usage-Based Metering:

This technique relies on meters or sensors that track resource usage and generate corresponding costs. This approach is suitable for:

  • Utility bills: Metering electricity, gas, and water consumption to determine per-unit costs.
  • Software licenses: Tracking software usage to calculate per-user or per-feature costs.
  • Telecommunication services: Monitoring data usage and call minutes to generate per-use charges.

1.3 Activity-Based Costing (ABC):

ABC is a more complex technique that assigns costs to specific activities based on their resource consumption. This approach is useful for:

  • Manufacturing processes: Identifying the cost of using specific machines or tools for each production step.
  • Project management: Determining the per-use cost of specific tasks or activities based on the resources utilized.
  • Service industries: Analyzing the cost of providing specific services based on the resources required.

1.4 Estimating based on historical data:

Using past data on resource usage and costs can be an effective method for estimating per-use costs when detailed tracking is not feasible. This approach involves:

  • Analyzing historical records: Identifying patterns and trends in past resource usage and costs.
  • Adjusting for inflation and other factors: Accounting for changes in costs over time.
  • Using statistical analysis: Applying regression analysis or other statistical methods to predict future per-use costs based on historical data.

1.5 Expert Opinion and Market Research:

In some cases, obtaining estimates from industry experts or conducting market research can provide valuable insights into per-use costs for specific resources.

1.6 Considerations for Accuracy:

  • Resource availability and capacity: Consider the availability of the resource and its capacity to handle different usage levels.
  • Maintenance and wear: Factor in the costs of maintaining and repairing the resource over time.
  • Overhead and indirect costs: Account for indirect costs associated with using the resource, such as labor, transportation, and administrative expenses.
  • Potential fluctuations: Recognize that per-use costs can fluctuate due to factors like supply and demand, seasonal changes, and market conditions.

By applying these techniques and considering the factors outlined above, organizations can obtain reliable estimates of per-use costs, enabling efficient resource allocation and cost control.

Chapter 2: Models for Analyzing Per-Use Costs
