IT Project Cost Estimation

The IT Project Cost Estimation is our solution by which a project is initially rated in regard to the basic key figures expenditure, function and time. With the help of a determined percentage distribution (based on: COCOMO-model) the planning is distributed into different phases. Moreover the updating and prediction process can be secured in the framework of ordering services. 

In order to allow different weightings in questions concerning cost estimation, bc has established a procedure with which we can support you. Taking into account the point in time of the estimation we offer you the following solutions:

Abstract

You want to review the results of an estimation and look for a second opinion. The bc QuickCheck CE Project (CE = Cost Estimation) will be our solution if you need timely information on the validity of estimation.

All significant roles are taken into consideration for expense calculation in IT QuickCheck CE. A prepared interview will help you to identify weaknesses within a very short amount of time. The customer gets an impression on further actions after he has received recommendations for action.

The bc QuickCheck CE does not replace a detailed estimation of expenses. Due to missing information on productivity, results can be falsified and respectively remain unconsidered.

  • Evaluation of the available cost estimation
  • Effort (PD, EUR), project phases, scope of functions, productivity
    • Evaluation of IT architecture
    • System components, data and interfaces
    • Evaluation of project and quality management
    • Resources, profiles, costs
    • Identification of strengths and weaknesses
    • Identification of inconsistencies with regard to costs, scope of functions, resources and IT architecture
    • Project risk assessment
    • Risks of target achievement, measures for risk reduction
    • Recommendations for further proceedings
    • Final presentation and documentation

The realisation is as follows:

ActivityDescription
Preparation of scope
  • Expectations
  • Rough project description
  • Risks (project, organisation)
Analysis of contents (interview)
Evaluation of feasibility
Preparing results
Final presentation

The consultancy services of bach consulting consist of the following:

  • Preparations and moderation
  • Conduct of analysis
  • Evaluation and analysis of results and documentation
  • Final presentation
  • Language/writing: German (Standard)

Services are classified into four categories. The package "Individual" can only be evaluated after the Initial briefing of volume and costs.

Abstract

You want to estimate a big project and simultaneously get to know your new team better. Then the estimation session is an option for you! We make use a strict systematised proceeding in the bc estimation session as in the delphi method. Unlike this method the estimation session includes group dynamic aspects – the experts do not estimate anonymously but in collective.

An estimation session is divided into three successive structured segments: preparation, implementation, follow-up work

  • Work breakdown structure
  • Subtasks, work packages in project
  • Estimation (based on templates for estimation)
  • Project effort in PD, EUR, time, resources, contents
  • Rough project planning
  • Tasks, resources, time, effort
  • First project proposal
  • Content/scope of functions, expenditure, time schedule incl. milestone plan

The realisation is as follows:

ActivityDescription
Preparation
  • Tasks
  • Develop work breakdown structures
  • Preparation of workshops
  • Tailoring of templates of estimation
Conduct a workshop
  • Conduct an estimation
  • Risk based estimation
  • Detailed discussion on work packages
  • Analogy to remaining work packages
  • Discussion of validity among experts
Follow-up
  • Rough project planning
  • First project proposal

The consultancy services of bach consulting consist of the following:

  • Moderation
  • Brainstorming
  • Recording
  • Coaching for estimation
  • Supply of templates for estimation

Quantity is a guide for measures. Projects respectively programs of large volume are subject to individual evaluation. Please feel free to contact us!

Abstract

You have to start although the contents are not yet known but the date of completion is already given.

bach consulting’s solution bc Invers CE Project takes into consideration that unforeseen events occur which require an immediate start a thorough planning beforehand. We know it from legal measures where immediate action is needed due to a short deadline.


  • Determination of scope of functions
  • Complete measurement with the help of IFPUG respectively COSMIC FFP
  • Determination of period of development
  • Evaluation of time (FP/PM) and costs (EUR/FP)
  • Review of target achievement
  • Evaluation of deadline and approved budget with the attainable data of productivity

The realisation is as follows:

ActivityDescription

Determination of budget target and scope of functions

  • Baseline available
  1. Determination of range of functions
  2. Determination of period of development
  • Baseline not available > bc Productivity Change for n projects (recommendation: n=3)

Determination of impacts on planning

  • Review of planning assumptions
  • Prioritisation of functions enabling target achievement

Review of target deadline

  • Review of target achievement to end of Project (scope of functions)

The consultancy services of bach consulting consist of the following:

  • Moderation
  • Brainstorming
  • Recording
  • Inverse calculation

Services are classified into four categories. The package "Individual" can only be evaluated after the initial briefing of volume and costs.

Abstract

You look for a procedure for a high level of transparency to be provided with basic information on traceable and verifiable commission. The function point analysis (FPA for short) is used for estimating the functional scope of an IT application. The result of a function point analysis is called “function points”, FP for short. bach consulting uses the methods of the International Function Point User Group (IFPUG for short) and of COSMIC.

In software development function points are used as a basis for cost estimation, benchmarking and for derivation of key figures for productivity, efficiency and quality.
