How do you use pull scheduling to coordinate work?

由人工智能和领英社区提供技术支持

Pull scheduling is a lean construction technique that helps you coordinate work across different trades and disciplines by involving them in the planning process. It is based on the principle of pull, which means that work is triggered by the downstream demand, rather than the upstream supply. In this article, you will learn how to use pull scheduling to improve your project performance, reduce waste, and increase collaboration.

1 What is pull scheduling?

Pull scheduling is a way of creating a project schedule that starts from the end and works backwards. It involves asking each trade or discipline what they need from the previous ones to complete their work, and when they need it. This way, you can align the activities and dependencies of each trade or discipline with the project milestones and objectives. Pull scheduling also allows you to identify and eliminate any unnecessary or non-value-adding work, such as rework, waiting, or overproduction.

O Planejamento puxado é uma técnica de planejamento reverso que foca na eficiência e na minimiza??o de desperdícios em projetos. Ao come?ar o planejamento pelo fim e definir o que cada equipe precisa dos passos anteriores, cria-se um cronograma mais alinhado com os objetivos reais do projeto. Esta abordagem facilita a sincroniza??o entre diferentes equipes, assegurando que cada uma tenha exatamente o que precisa, quando precisa, o que ajuda a evitar retrabalhos, tempos de espera e superprodu??o. Por fim, o planejamento puxado otimiza o fluxo de trabalho e contribui para a entrega de projetos mais enxutos e eficazes.

2 How to create a pull schedule?

To create a pull schedule, it’s important to involve all the relevant stakeholders, such as owners, designers, contractors, subcontractors, and suppliers. A collaborative tool, such as a whiteboard, sticky notes, or software, can be used to facilitate the process. The steps involve defining the project scope and goals and identifying the major milestones and constraints. Work backward from the last milestone to determine what each trade or discipline needs to achieve it. Write down each activity on a sticky note and place it on the board, then repeat the process for each milestone until you reach the first one. Be sure to consider dependencies and interdependencies between activities. Review the schedule and validate it with all stakeholders (making any necessary changes or improvements).

Para criar um cronograma de puxada eficaz, envolva todas as partes interessadas, utilize ferramentas colaborativas, defina escopo e metas, identifique marcos e restri??es, trabalhe de trás para frente a partir do último marco, anote atividades em notas adesivas considerando dependências, revise e valide com as partes interessadas, ajustando conforme necessário para garantir a precis?o do planejamento.

3 How to use a pull schedule?

Once you have created a pull schedule, you need to use it to manage and monitor your project execution. This will help you communicate the expectations and commitments of each trade or discipline, and ensure they are aligned with the project goals and milestones. Additionally, it will allow you to track the progress and performance of each activity, and identify any issues or risks that may affect the schedule. You can also use the pull schedule to implement a feedback and learning loop, where you can review the results and outcomes of each activity and make any adjustments or corrections as needed. Ultimately, it will encourage collaboration and problem-solving among the trades and disciplines, as well as foster a culture of continuous improvement.

5 What are the challenges of pull scheduling?

Pull scheduling is not without its challenges, and it's important to be aware of them and address them properly. Resistance to change from stakeholders used to traditional or push-based scheduling methods may be an issue, as well as a lack of clarity or alignment among stakeholders regarding the project scope, goals, or deliverables. Poor communication or coordination between stakeholders can result in delays or conflicts in the schedule. Unforeseen changes or uncertainties due to external factors such as weather, market conditions, or regulations may also present a challenge.

No pull scheduling, o trabalho é coordenado de forma que as tarefas s?o puxadas conforme a necessidade e capacidade, em vez de empurradas para os recursos. Isso significa que as equipes só iniciam uma nova tarefa quando têm capacidade e demanda para isso, evitando sobrecarga e desperdício. A coordena??o é feita de forma mais fluida e adaptativa, permitindo uma melhor utiliza??o dos recursos e uma resposta mais ágil às mudan?as.
