This research aims to explore the use of agile methodology in managing the construction of a playground park, contrasting

it with lean methodology. The company has been using the lean methodology for managing construction projects, which

emphasizes efficiency$($e$.$g$.$ value stream mapping it represents the flow of materials, information, and processes in a

system$)($e$.$g$.$ just in time delivery it involves delivering materials and supplies only when they are needed$)($e$.$g$.$ visual

management involves using visual aid, such as charts, graphs and signs to information and improve communication$)($e$.$g$.$

teamwork and collaboration it encourages cross$-$ functional teams to work together to improve processes and

outcomes$),$ elimination of waste and continuous improvement over the past years. While this approach has been

successful for simpler projects, it lacks the flexibility to adapt to changing requirements and unexpected issues that may

arise during the construction process. As a result, the company has experienced delays, cost overruns, and dissatisfied

stakeholders in some of its recent projects. Therefore, the agile approach is chosen for its flexibility and ability to adapt to

changing the project requirements, including breaking down the project into smaller sprints, customer collaboration $($e$.$g$.$

stakeholders, school administration, teachers and students$),$ respond to change $($e$.$g$.$ If school decide to add a sensory

play are for children with special needs$),$ continues improvement$($ e$.$g$.$ after each sprint, the team reviews what went

well and could be improved$),$ cross$-$ functional teams$($e$.$g$.$ a team including designers, builders, and safety experts

collaborating to ensure that playground is both fun and safe$),$ making it suitable for a complex projects like playground

construction. The company has seen that lean methodology take time in completing the project due to the following $,$ less

production and over production which result in scheduling time, so the company want to use agile method because it have

a timeframe of $1-4$ weeks to complete the work and it collaborate with all stakeholders.

Due to the use of lean methodology in different project over the past $4$ years has decline due to lack of planning,

execution, costs overuns and delays, here are the effective planning$($EP$)$ metric from $2020$ to $2024,$ in $2020$ EP was $96\%,$

$2021$ EP $80\%,2023$ EP $60\%,$ and $2024$ ATP is $50\%.$ As a result the company has been struggling to meet the demand

deadlines which have left customers dissatisfied
