Tactical planning typically covers a time frame of six months to two years, and it focuses on implementing the strategic plan. In SIMCEL, it refers to the plans that are created regularly (weekly, monthly, and so on) and that are used to create the committed plan. Beyond the tactical plan, SIMCEL also features a **Budget Plan**, or strategic plan, aimed at setting broad business goals across 2 to 5 years and focusing on key areas like brand, channels, and regions. ## Creating a new tactical plan Click **+ Plan** to open the SIMCEL plan menu. SIMCEL toolbar with the + Plan button highlighted, opening the plan creation menu To create a new tactical plan, for example a plan for February 2026: Set the title of the plan to **Feb 2026**. Select **Tactical plan**. Select the forecasting method. You can try the **Light Gradient-Boosting Machine (LightGBM)** method. Set the **Plan Period** to **Feb 2026 - Jan 2027**. Add a description. This is optional. Click **Create**. New plan dialog with the title Feb 2026, the Tactical plan type selected, the LightGBM forecasting method, and a plan period of February 2026 to January 2027 The screen shows a loading page while the forecaster generates the demand projection for the new plan. This may take a few minutes. Loading screen shown while SIMCEL's forecaster generates the demand projection for the newly created plan Once the loading completes, you have successfully created your first plan in SIMCEL to forecast your future demand. The default scenario displayed is the **Forecast Base**, which shows the unbiased demand projection, free from any event influencing the demand.
