Voici comment vous pouvez estimer les délais d’un projet dans une stratégie informatique en tenant compte des facteurs clés.

Clarity of the project scope is an unquestionable prerequisite before starting any type of development. Despite a lot of pressure to establish a project timeline, set a budget, or even begin code development, the IT leader must remember the importance of a detailed understanding of what the project entails, including all deliverables and tasks required to complete it. Depending on the organization's level of project governance maturity, it may not be an easy task, but I believe that this negotiation is part of the skills necessary for the role of strategic IT leader. Prepare a presentation showing the schedule, costs and benefits considering the planning phase of the project scope, and only move forward after the stakeholders agreement.

When estimating project timelines in IT strategy, meticulous planning is essential. Start with a clear scope to define objectives and deliverables precisely, preventing scope creep. Analyze team resources thoroughly to allocate skills effectively. Identify and mitigate risks early to avoid delays. Historical data informs realistic timelines, while iterative reviews adjust based on feedback for alignment with milestones. Integrate client input continuously to ensure timelines meet evolving needs. Expert precision ensures accurate estimations for successful project execution.

Estimating project timelines in IT strategy involves several key factors to ensure accuracy and feasibility. Start by defining the project scope, detailing all tasks and deliverables. Assess resource availability, including team members' skills and workload. Analyze historical data from similar projects to gauge typical durations and identify potential bottlenecks. Factor in dependencies between tasks, understanding how delays in one area can impact the overall timeline. Incorporate risk management by identifying potential issues and planning contingencies. Lastly, engage stakeholders in the estimation process to gain insights and ensure alignment. By considering these factors, you can create realistic and achievable project timelines.

Thoroughly define project scope, objectives, and deliverables. Engage stakeholders to ensure alignment and minimize scope creep. Break down tasks into manageable units for accurate estimation.

Many people make this mistake. They quickly define scope and get sign-off so they can start delivery and show progress. After 25 years leading IT Projects, I've learnt from my mistakes. Here's the right way. Define the scope with your team. Your team knows the work best. Encourage new ideas and different ways to deliver the product. Then get stakeholder input. This takes time and can be challenge but the result is scope clarity and agreement for everyone. IT Projects don't go wrong, they start wrong.

Assess available resources, including human capital, technology, and budget. Consider team expertise and availability, as well as potential dependencies on external vendors or partners.

When assessing resource availability it is critical to look at how resources time are allocated across other projects and the general day-to-day aspects of their jobs. If resourcing becomes a limiting factors organizations can turn to backfills to manage other tasks or engage with 3rd party resources to shoulder some of the effort of the project.

On resource planing be careful planing the attrition or rotation of resources. In demanding and competitive talent markets it's a critical point to keep in mind and is good to plan for knowledge transfer and onboardings.

Through assessing the quantity of team members and their skills, it's crucial to consider their current workload and potential capacity for additional tasks. Understanding the dynamics within your team—such as communication channels and collaborative tools—can streamline workflows and prevent delays. Additionally, evaluate the availability of hardware, software licenses, and any external resources needed. Anticipate potential bottlenecks by identifying dependencies early on and devising contingency plans. By optimizing resource allocation and ensuring alignment with project requirements, you can create more accurate timelines that reflect realistic milestones and enhance overall project success.

Risk management is essential for accurate IT project timelines. At first, you use large buffers in the estimation to handle unknown risks, but these buffers get smaller with experience. Historical data is useful, especially if you were involved in those projects, as it offers precise insights. Identify risks like technical issues, dependencies, and resource availability. Using historical information and adding buffer time helps create a schedule that can handle delays without missing deadlines

Avoiding delays and cost overruns comes down to how you describe your Risks. Here's how to do it right: Describe the potential problem and the specific impact - this is important because the impact needs a mitigation. For example: Risk: Contract negotiations with IT supplier may take additional time and not be complete by June 25th which impacts delivery of our Design documents by July 10. Mitigation: Daily contract progress meetings with Supply Chain. Weekly reporting to leadership. Review delivery schedule for any impacts. Pro tip: Leaders want to see you've considered all scenarios. If the risk is realized (it becomes an Issue), what will you do next? E.g. Rework schedule and escalate to senior leadership.

Identify potential risks and uncertainties that may impact project timelines. Develop mitigation strategies and contingency plans to address unforeseen challenges proactively.

Identify potential risks that could impact the project timeline. Develop mitigation strategies, including contingency plans for unexpected issues. Regularly review and adjust plans to address new risks as they arise. Incorporate risk assessments into your project planning to proactively manage uncertainties. This approach minimizes disruptions and keeps the project on schedule, enhancing the accuracy of your timeline estimates and increasing the likelihood of project success. A perfect example of this, is when I promised my boss that I would complete a project by the end of the week (I never give promises) and ended up in a bicycle accident. I wasn't able to fulfill my promise, but managing risk is key to successful delivery.

You can mange the risks with empiricism, short cycles with fast feedback to prevent that risk realization have large impact in the project.

Very few projects are truly unique, unless you're NASA :) Reference Point Estimating is your best friend. Many people don't do this... We want to get 'shovels in the ground' and show progress. But this it the best investment of time you can make at the start of a project. Find similar projects and see what they did, how much it cost, how long it took. Ask your friends, your PMO, vendors, sponsors. Not only do you get good data for your estimates, you also build relationships and trust.

Leverage past project experiences and historical data to inform timeline estimation. Analyze similar projects' timelines, challenges, and outcomes to identify patterns and factors influencing project duration.

For the historical data you can relay in the team collective memory, and what they developed as team's "common sense". Bare in mind that some times a pushback of the team may seam irrational, but remind to check if you are getting historical data (explained in a particular way)

Leverage data from past projects to inform your estimates. Analyze how similar projects were completed, noting any patterns or common issues. Use this historical data to create more accurate and realistic timelines, adjusting for any differences in scope or complexity. IT Systems to Leverage Historical Data: • Project Management Software (JIRA, Asana, Trello) • ERP Systems (SAP, Oracle) • CRM Systems (Salesforce) • Data Analytics Tools (Tableau, Google Analytics) • Apache Hadoop • Grafana

Adopt an iterative approach to timeline estimation, allowing for ongoing refinement based on evolving requirements and insights gained during project execution. Regularly review and update timelines to ensure accuracy and alignment with project goals.

Collaborate closely with clients to understand their expectations, priorities, and constraints. Solicit feedback and incorporate client input into timeline estimation to ensure alignment with their needs and objectives.

Client input is essential for a robust IT strategy. Feedback loops are key for continuous improvement and aligning with client needs. Key Points: • Identify pain points and adapt to changing requirements. • Enhance user experience through regular communication. • Respond promptly to client concerns. • Utilize iterative development processes. • Drive innovation and efficiency by incorporating feedback. Effective feedback loops ensure projects meet both current and future demands, boosting client satisfaction and fostering innovation.

Consider external factors such as regulatory compliance, market dynamics, and technological advancements that may influence project timelines. Anticipate potential bottlenecks or delays and build buffers into the timeline to accommodate unforeseen circumstances. Foster open communication and transparency among project stakeholders to address challenges proactively and maintain alignment throughout the project lifecycle.

Experts in the process are key. Understand your environment and which metodology better fit. Don't get tied on the oficial way of going wheather Agile or SCRUM or other trends. Get the righ one for you, your context and get a good expert on it to lead the project.
