5. Advantage
• First of all, the advantage of the top down approach is it
gives you a broad view of your revenue potential. It's
simpler and it's more streamlined. It's going to be quicker to
actually do. It's great for doing a feasibility analysis, as well,
because you can do it very quickly.
• There are benefits to a top-down management style,
especially for larger teams that consist of multiple smaller
teams or groups that function together in a broader
organizational hierarchy
6. Disadvantage
• Senior managers might lack a critical understanding of the
departments they are creating budgets for. Unrealistic
expectations might permeate the budget due to a lack of
experience with each department. Employees might be less
motivated to implement a budget they have no input on.
• Significant limitations of the top-down approach include
low community ownership and sustainability and high
levels of dependency.
• Community Ownership.Self-Silencing.Backlash.Poor
Sustainability.Weak Focus on Prevention.
7. Bottom up approach
In this approach We focus on breaking up the problem into
smaller parts. In bottom up approach, we solve smaller
problemsBottom-up Approach is a democratic and
consultative style of decision making, organizational change
and leadership, in which employee ...
9. Advantage
• Bottom-up troubleshooting is an effective and efficient approach
for situations when the problem is suspected to be physical. Most
networking problems reside at the lower levels, so implementing
the bottom-up approach often results in effective and perhaps
fast results.
• While a bottom-up approach allows decisions to be made by the
same people who are working directly on a project, the top-down
style of management creates distance between that team and
decision-makers. This can lead to poorly-informed decisions if
leadership doesn't ask for input or feedback from their project
team.
10. Disadvantage
• Bottom-up budgeting often results in a more accurate
budget, but it also requires significantly more time and
resources to complete. In some cases, bottom-up budgeting
may have the downside of resulting in cost overruns as well.
• Potential conflicts: Decision-making and goal achievement
may be slower because your company considers all ideas, but
disagreements and conflicts of interest may arise and slow
productivity down further.
11. Difference between top down and
bottom up approach
• Top-down modeling is a method of creating and designing
the geometry all within an assembly. This is sometimes
called “in-context design” because everything is created in
the context of an assembly. The alternative to this is called
bottom-up assembly modeling where every individual part
is created separately.
• Bottom-up refers to the way it is built up from the smallest
pieces of sensory information. Top-down processing, on the
other hand, refers to perception that is driven by cognition.
Your brain applies what it knows and what it expects to
perceive and fills in the blanks, so to speak.
12. • Improved employee trust. ...Greater collaboration.
...More synchronicity between managers and
employees. ...Faster innovation. ...Fewer knowledge
gaps. ...Faster risk identification. ...More diversity in
knowledge and skills. ...Improved morale.
• In Bottom-Up Model, the focus is on identifying and
resolving smallest problems and then integrating
them together to solve the bigger problem. In Top-
down Model, the focus is on breaking the bigger
problem into smaller one and then repeat the process
with each problem.
