Estimate An estimate is a probability assessment based on skill and experience of the time and resources required for the delivery of a specified product that has been considered at length during product-based planning. (Roberts 2007: 112) Anna Ilmer & Manuel Leupold Planning: Time and cost 5
2. Estimating techniques Without any references to any stored data or prior experience top down & bottom up Delphi technique analogy Require estimation data from previous projects work distribution standard project / product Anna Ilmer & Manuel Leupold Planning: Time and cost 6
Top down and bottom up Top down: Created at the beginning of the project takes the whole project and applies an overall timescale and cost. (Roberts 2007: 112) No possibility for detail planning High level nature May contain risky assumptions Focus on TIME / COST / QUALITY Anna Ilmer & Manuel Leupold Planning: Time and cost 7
Top down and bottom up Bottom-up: more detailed than Top-down Breaks a product into a set of smaller product Anna Ilmer & Manuel Leupold Planning: Time and cost 8
Top down and bottom up TIME Stage 1 8 weeks Stage 2 8 weeks Stage 3 10 weeks Stage 4 15 weeks Stage 5 15 weeks COST 20.000 $ 25.000 $ 45.000 $ 65.000 $ 5.000 $ QUALITY Feasibility study report Need analysis report Design report Developed solution Tested,implememnted solution QUALITY Gathered data Drafted report Reviewed report Amended report Approved report Presented report COST 3.000 $ 8.000 $ 2.000 $ 4.000 $ 2.000 $ 1.000 $ TIME 1 week 2 weeks 2 weeks 1 week 1 week 1 week Anna Ilmer & Manuel Leupold Planning: Time and cost 9
The Delphi technique Named after the greek oracle, wich was consulted before all major undertakings Experts estimate the effort (or budget) for products other experts review the estimation and give an anonymously feedback the first experts are encouraged to revise t their earlier estimates in the light of these o other views Anna Ilmer & Manuel Leupold Planning: Time and cost 10
Analogy Comparing the project, or aspects of it, with something similar is one way in which estimates can be developed. (Roberts 2007: 114) Anna Ilmer & Manuel Leupold Planning: Time and cost 11
Workdistribution May be used only for similar projects Use of experience and reliable data from former projects Show the distribution of effort or budget across the standard project lifecycle or across different types of resource Anna Ilmer & Manuel Leupold Planning: Time and cost 12
Workdistribution Project total 100% Project Management initiation 5% 5% Need Sales Analysis 25% 35% Solution Operations Design 15% 25% Solution Third parties Dev. 35 10 % Solution IT implementati 35% on 10% Anna Ilmer & Manuel Leupold Planning: Time and cost 13
Standard project/product Matrix for working out effort for future project Based on data from repeatedly carried out projects For repeatable work, which varies in size and complexity For accurate estimation, size and complexity should be measurable Anna Ilmer & Manuel Leupold Planning: Time and cost 14
Standard project/ product COMPLEXITY LOW MEDIUM HIGH SIZE SMALL 1 2 3 MEDIUM 3 5 9 LARGE 5 10 15 Anna Ilmer & Manuel Leupold Planning: Time and cost 15
3.Development of a resource plan Resource management Timescale identification Product flow diagram / PERT diagram Gantt Chart Cost estimate Resource plan Resource plan with financial information Anna Ilmer & Manuel Leupold Planning: Time and cost 16
Resource management Capital Office Equipment, computer hardware Non-human ressources Travels, advanced education, expenses Human resources Skills, experience, effort, productivity Anna Ilmer & Manuel Leupold Planning: Time and cost 17
Human resources - Productivity People will not be 100% productive. Productivity does not always increase when more people are allocated to a task. People have different productivity rates. Productivity increases are usually temporary. Anna Ilmer & Manuel Leupold Planning: Time and cost 18
Dependable productivity estimates Let people estimate their own work. Make planning assumptions clear. Agree product descriptions. Look at metrics from previous work. Negotiate penalty/reward clauses. Anna Ilmer & Manuel Leupold Planning: Time and cost 19
