How do you estimate the duration and effort of each project stage?

Top-down estimation is a powerful tool when you have a strong vision and a grasp of the big picture. It's like having a roadmap for your project - you know where you're headed and can plan the best route to get there. But remember, it's crucial to stay flexible and adjust as you dive into the nitty-gritty of each stage. Keep your eyes on the prize, but don't forget to zoom in on the details that make your project unique. Let's make those estimates work for us, not against us! ???? #ProjectManagement #TopDownEstimation #StayAdaptable

Begin by breaking down the project into major phases or milestones and assigning a rough estimate of time and resources to each based on past experience, expert judgment, or industry benchmarks. Then, refine these estimates by considering specific factors such as project complexity, team capabilities, and potential risks. While top-down estimation provides a quick and high-level overview, it's important to validate and adjust estimates as more detailed information becomes available throughout the project lifecycle. Regularly review and update estimates based on actual progress and feedback to ensure accuracy and alignment with project objectives.

As a Product Owner, I experienced scope creep during Sprint Planning due to underestimation. Despite having a clear vision and high-level understanding, the detailed tasks proved more complex and dependent than expected. Consequently, we faced delays in delivering planned features, leading to overtime work, decreased team morale, increased stress, and potential quality issues.

O Método 1: Estimativa Descendente é uma abordagem em que a estimativa de dura??o e esfor?o é feita de forma geral e depois é detalhada. Aqui est?o os passos principais: Estimativa Inicial: Comece com uma avalia??o ampla do projeto, usando dados de projetos semelhantes. ?? Divis?o em Fases: Quebre o projeto em fases ou componentes maiores. ?? Refinamento: à medida que o projeto avan?a, refine as estimativas para cada fase com mais detalhes. ??? Valida??o: Revise as estimativas com a equipe para garantir precis?o. ? Esse método é útil para projetos em estágio inicial, pois permite uma vis?o rápida sem entrar em muitos detalhes desde o come?o. ??

Bottom-up estimation is like building a puzzle - you start with the small pieces and work your way up to see the big picture. It's a meticulous process that requires attention to detail and a deep understanding of the project scope. As a leader in Business Intelligence, I appreciate the precision and accuracy that bottom-up estimation brings to project management. It's a method that aligns with my analytical nature and passion for data-driven decision making. Plus, it's a great way to mentor team members on the importance of thorough planning and analysis. Just remember to factor in some wiggle room for those unexpected hiccups! ????

Team members responsible for executing the work provide input based on their expertise and experience, considering factors such as task complexity, resources needed, and potential risks. These are aggregated to calculate the overall duration and effort for each project stage or phase. Bottom-up estimation provides a more granular view of project and is Time-consuming and resource-intensive. But, the level of detail obtained allows for better identification of potential bottlenecks, resource constraints, and dependencies, enabling more informed decision-making and resource allocation. Regularly revisiting and refining bottom-up estimates throughout the project lifecycle helps ensure accuracy and alignment with project goals and constraints.

Scope creep occurred during Sprint Planning due to inadequate consideration of dependencies and contingencies. Detailed task breakdown and estimation were done, but when challenges arose or tasks took longer than expected, it caused delays and increased effort. The consequences were a cascading effect on the project timeline, missed deadlines, increased pressure on the team, compromised resource allocation, and potential stakeholder dissatisfaction.

O Método 2: Estimativa Ascendente envolve uma abordagem mais detalhada e precisa, onde as estimativas s?o feitas a partir de cada atividade individualmente. Aqui est?o os passos principais: Identifica??o de Atividades: Liste todas as atividades necessárias para o projeto. ?? Estimativa Detalhada: Cada membro da equipe fornece estimativas de dura??o e esfor?o para suas respectivas atividades. ??? Agrega??o: Some todas as estimativas individuais para obter a dura??o e o esfor?o total do projeto. ?? Revis?o: Revise e ajuste as estimativas agregadas com a equipe, garantindo precis?o e viabilidade. ? Esse método é eficaz para projetos complexos, onde a precis?o é fundamental e as atividades s?o bem definidas. ??

Using a hybrid estimation approach, combining top-down and bottom-up methods, mitigates scope creep in Sprint Planning. It balances high-level planning and task analysis, establishing initial scope and timeline through top-down estimation, and refining estimates with bottom-up techniques. Not adopting this approach risks scope creep, underestimation, and unrealistic timelines with top-down estimation alone, or overestimation and excessive focus on minor tasks with bottom-up estimation alone. The hybrid approach minimizes scope creep by considering the bigger picture and granular details.

O Método 3: Estimativa Híbrida combina elementos da estimativa descendente e ascendente, aproveitando os pontos fortes de ambos os métodos. Aqui est?o os passos principais: Vis?o Geral: Comece com uma estimativa descendente para ter uma ideia inicial do projeto. ?? Detalhamento: Identifique as atividades principais e envolva a equipe para fazer estimativas detalhadas (ascendente) nas partes críticas. ???? Compara??o: Compare as estimativas ascendentes com a vis?o geral e ajuste conforme necessário. ?? Valida??o: Revise as estimativas finais com a equipe para garantir precis?o e viabilidade. ? Esse método é eficaz em projetos complexos, proporcionando um equilíbrio entre rapidez e precis?o. ??

Begin by using top-down estimation to establish high-level estimates for major phases or milestones based on historical data, expert judgment, or industry standards. Then, complement these estimates with bottom-up estimation techniques to break down the work into smaller tasks or work packages and gather detailed input from team members responsible for executing the work. Combine the high-level and detailed estimates to refine and validate the overall duration and effort for each project stage, taking into account factors such as task complexity, resource availability, and potential risks. Hybrid estimation leverages the strengths of both approaches,

When estimating effort and duration in Sprint Planning, it is important to consider several factors. These factors include the scope and complexity of tasks, dependencies and constraints, team skills and availability, and the quality of data and assumptions. Neglecting these factors can have consequences such as scope creep, missed deadlines, compromised quality, overburdened resources, inefficient allocation, and distorted estimates. It is crucial to analyze these factors accurately to ensure the success of the project.
