How to Make Quality Decisions Using a Decision Analysis and Resolution (DAR) Process
How to Make Quality Decisions Using a Decision Analysis and Resolution (DAR) Process Briefing Objectives ▼ Understand how to make quality decisions using a Decision Analysis and Resolution Process Enable attendees to successfully implement the Decision Analysis and Resolution (DAR) Process within their organizations and/or on their projects − Understand why DAR is important − Become familiar with the DAR process and the tools and techniques used in implementing DAR 2 Outline ▼ What is DAR? ▼ Why do we need DAR? ▼ Overview of the DAR Process ▼ DAR Process Details ▼ DAR templates, tools, and references 3 What is DAR? ▼ The purpose of Decision Analysis and Resolution is to analyze possible decisions using a formal evaluation process that evaluates identified alternatives against established criteria Or more plainly: a process to make key decisions more objectively and wisely 4 What is DAR? (2) ▼A formal evaluation process: Provides documented, measurable, and objective criteria − Numeric – weighting to reflect importance [Non-numeric-more subjective high-medium-low] Can vary in formality, type of criteria, methods employed − More risk? more formal methods with stringent requirements and needs (may require separate plans, months of effort, meetings to develop and approve criteria, simulations, prototypes, piloting, and extensive documentation) 5 What is DAR? (3) Has a higher probability of selecting a solution that meets multiple demands Involves: » Establishing the criteria for evaluating alternatives » Identifying alternative solutions » Selecting methods for evaluating alternatives » Evaluating solutions using the criteria and methods » Selecting solutions based on evaluation criteria » Documenting results and rationale for decision 6 Why Do We Need a DAR Process? ▼ Making informed, high quality decisions reduces organizational/project risk and increases probability of success Following a structured and disciplined process for making highly complex and/or high risk decisions leads to quality decisions Helps to gain stakeholder buy-in for project decisions Encourages more disciplined objective thinking Reduces or eliminates subjectivity and bias 7 Dilbert on Decisions 8 Dilbert on Decisions (2) 9 Perspective Life is the sum of all your choices. -Albert Camus ▼ We make decisions every day; everything we say and do is the result of a decision, whether we make it consciously or not. For every choice, big or small, there's no easy formula for making the right decision. Many managers and Project Managers rely on their gut – their experience and instincts – to make major decisions. Very risky! A downside of this approach is that it is difficult to discuss with others how or why the manager came to the decision they did. In fact, it is the antithesis of group decision-making. Also, the decision is not often recorded for future use and re-evaluation so we can ask: − “Was this a good decision?” (objectives and criteria) − “How can we make consistently better decisions across the project / organization?” (lessons learned) 10 Do All Decisions Need to Follow a Formal Process? 11 When You Use the DAR Process? ▼ Organizations/Projects need to define their own thresholds or triggers for executing the DAR process Generally, DAR is used for decisions that are high risk or have high impact on the project DAR thresholds or triggers are usually documented in the Project Plan ▼ Example thresholds and/or criteria: Schedule impact of >10% Cost impact of >15% Quality Impact of >15% Impact to safety or security Purchases over $10,000 12 What Decisions Do I Apply DAR To? ▼ DAR Process can be used in many types of Organizational/project decisions: Technical decisions Design decisions Make or Buy decisions Software tools Trade studies Change Control Boards (CCBs) − Major changes to processes or products Risk Management Boards − Select a risk mitigation approach Contractor source selection 13 Example Guidelines For Invoking DAR These could be formal “trip-wires”: ▼ When decisions are directly related to topics of medium or high risk ▼ When decisions are related to changing work products under CM (key baselined documents such as requirements baselines, project plans and schedules, etc.) ▼ When project management or engineering decisions could cause unacceptable project / schedule delays ▼ When management and engineering decisions affect the ability to achieve project goals ▼ When management and engineering decisions relate to safety or security issues ▼ When there are multiple approaches or multiple solutions to architecture or design issues ▼ On material procurement where 20 percent of the parts constitute 80 percent of the total material costs 14 DAR Example ▼ Make-Reuse-Buy trade study List four alternatives: make, reuse, buy and do nothing List alternatives from all potential vendors. Evaluation criteria would include items such as cost, schedule, performance, risk, number of requirements not met, etc. 15 Overview of the DAR Process 1 2 3 Select Decision Team Define the Analysis Objective and Establish Evaluation Criteria Identify Available Solutions 4 5 6 Select Evaluation Method(s) That are Best for the Problem Domain Evaluate Available Solutions Using Established Criteria and Methods Select Solutions and Prepare Evaluation Report 16 1. Select Decision Team ▼ Process Guidance When an issue is identified that requires use of the DAR Process (according to the Project’s defined guidelines), the project manager selects stakeholders (including a facilitator) to assist in decision making. ▼ The Organization/Project’s defined guidelines are entry criteria to this process. They are the triggers to determine which issues should be subjected to a formal evaluation process. ▼ DAR can involve many areas of an Organization/Project. The Decision Team should have the skills necessary to address the issue at hand. 17 1. Select Decision Team (2) ▼ Process Guidance Team must have necessary knowledge and skills for the issue to be decided Team will research and evaluate possible alternatives ▼ Project Mananger needs to select knowledgeable team members to make informed decisions. Some decisions are critical to program success, so there needs to be confidence that the best decision was made by a knowledgeable team 3-5 team members is ideal Possible Consequences – if this task is not done well ▼ There may be lack of confidence that the best decision was made if the decision team lacks appropriate skills and viewpoints. Implementation Examples – how easy it is to satisfy this task ▼ Select decision team members who actually do the work involving the issue, and those who will be affected by the decision. ▼ Also consider selecting a team member who is less involved, to ensure a balance of the “outsider” perspective. 18 2. Define the Analysis Objective and Establish Evaluation Criteria ▼ Process Guidance Facilitator leads team to define analysis objective and establish scope of the decision effort for each task in DAR Process. The team documents and maintains the evaluation criteria, which provide the basis for evaluating alternative solutions, by doing these tasks: − Analyze and establish scope of the issue − Define evaluation criteria − Define weight values to criteria based on relative importance − Define scoring algorithms to determine percent satisfaction for criteria − Define overall scoring thresholds of acceptability − Document rationale for selection/rejection of evaluation criteria − Identify acceptable timeline for decision completion ▼ In this task, you establish what you are evaluating and what you need to know. 19 2. Define the Analysis Objective and Establish Evaluation Criteria (2) ▼ Process Guidance There are many ways to determine and document the criteria for an issue, including a flow chart, decision tree, triangle tool (with weights at each corner), or spreadsheet matrix form. Tools that may be used for this activity include: − Decision Analysis and Resolution Record Form or − Decision Analysis Matrix ▼ Evaluation Criteria are based on needs, requirements, business objectives, assumptions, etc, depending on analysis objective. Can include technology limitations, environmental impact, risks, life cycle costs, schedule, performance, reliability, etc. 2-5 criteria are usually enough Possible Consequences – if this task is not done well ▼ Inappropriate criteria can lead to the wrong decision that doesn’t solve the issue. ▼Critical requirements can be missed. Implementation Examples – how easy it is to satisfy this task ▼ Tie evaluation criteria to business and project needs. ▼ Solicit knowledgeable team members to establish criteria. 20 3. Identify Available Solutions ▼ Process Guidance Facilitator leads team to identify available solutions: − List available solutions and weighting criteria − Search related technical/scientific domains, internet, and/or historical data to validate alternatives − Identify risks for alternatives ▼ There are many ways to come up with alternative solutions to your issues, for example: Brainstorming Literature search Market research Competitor analysis Internet Historical data 21 3. Identify Available Solutions (2) ▼ Process Guidance Document the proposed alternatives and their risks ▼ Documenting the possible alternatives on a form or spreadsheet ensures that potential solutions are appropriately captured. Then viable solutions can be selected for evaluation. Documenting the reasons for accepting or rejecting alternatives ensures that anyone in the future making the same decision will know the rationale behind the entire decision process so that mistakes are not repeated Possible Consequences – if this task is not done well ▼ Not documenting the decision process could lead to missing a viable solution. ▼ Future project managers would not have the historical data on why certain decisions were made, so may repeat unacceptable solutions. Implementation Examples – how easy it is to satisfy this task ▼ List the alternative solutions on a form to better evaluate and accept / reject each solution as a viable option for evaluation. ▼ Store the data sheets on a shared repository; report to Organization if appropriate to share a best practice. 22 4. Select Evaluation Method(s) That are Best for the Problem Domain ▼ Process Guidance Facilitator leads team in determining Evaluation Methods to be applied in selecting a solution. − methods for evaluating viable solutions against criteria vary for technical/nontechnical issues (simulations, statistical analysis, decision theory) − level of detail of a method should be commensurate with cost, schedule, performance, and risk impacts ▼ There’s no one formula for making the right decision 23 4. Select Evaluation Method(s) That are Best for the Problem Domain (2) ▼ Process Guidance Example Evaluation Methods: − Cost/Benefit Analysis − Engineering Trade-Off Analysis − Delphi Method − Simulation − Feasibility Study - Pair-Wise Comparison - Prototyping - Testing Data Analysis - Reference to “Best Practice” - User Reviews ▼ Cost and criticality of the decision may be considerations when selecting which method to use Possible Consequences – if this task is not done well ▼ Using a method that is not detailed or rigorous enough for the criticality of the issue will not exercise the options well enough, potentially putting the project at risk. Implementation Examples – how easy it is to satisfy this task ▼ Select evaluation method appropriate to the criticality and complexity of the issue to be solved. 24 5. Evaluate Available Solutions using Established Criteria and Methods ▼ Process Guidance Facilitator leads team to evaluate the selected alternative solutions (determined in task 3): − involves analysis, discussion, and review Scoring (determined in task 2) is substantiated Conclusions are reached using selected methods (determined in task 4) ▼ Evaluate the viable solutions from the initial list of possible alternatives. As a guideline, there should be 2 to 5 alternative solutions identified for evaluation 25 5. Evaluate Available Solutions using Established Criteria and Methods (2) ▼ Process Guidance Consider new alternative solutions, criteria, or methods if outputs do not yield desirable results or are inconclusive − Repeat tasks 2-5 until one or more viable solutions can be selected ▼ Taking the time to re-evaluate solutions as needed can yield valuable results. Possible Consequences – if this task is not done well ▼Selecting too many solutions to consider could result in some of them not being given thorough consideration. ▼ Rushing to a decision when time should be made to re-evaluate alternative solutions when necessary may result in wasted time/effort implementing an inappropriate solution. Implementation Examples – how easy it is to satisfy this task ▼Limit solutions to be evaluated to 2-5 viable options. ▼Balance time available to make a decision with the criticality of the issue to ensure a credible solution is selected. 26 6. Select Solutions and Prepare Evaluation Report ▼ Process Guidance Selecting solutions involves weighing the results from the evaluation of alternatives − Determine composite score for each alternative − Assemble and document the data for final selection − Document results and selection rationale ▼ Once you select your solution, decide if it is too risky – do you need to re-evaluate? 27 6. Select Solutions and Prepare Evaluation Report (2) ▼ Process Guidance Prepare an Evaluation Report documenting decision process − include any risks associated with selected solution − include rationale why other alternatives were not selected Submit Evaluation Report to Project Manager for final approval and distribution ▼ Important to record results and lessons learned for future use and re-evaluation: to know if this was a good decision to be able to make consistently better decisions across the project / organization Possible Consequences – if this task is not done well ▼ Not adequately documenting the decision data may not give the project manager the needed background for approval. Implementation Examples – how easy it is to satisfy this task ▼ Document the rationale for selection on the initial Decision Analysis Form. 28 Process Improvement Habits Habits to Break Habits to Make Making “gut” decisions without a Maintain objectivity by assembling a team of Not documenting the decision Use a decision form listing alternatives, selection team and without conducting a formal analysis, resulting in a subjective decision.

And, no documented guidelines to determine which events or items should be subjected to a formal evaluation process. ▼ A formal process description is not used or tailored ▼ Evaluation criteria are not documented prior to analysis and decision point ▼ Rationale is unavailable when needed to understand / re-use earlier decisions ▼ Lessons learned are not collected and analyzed about the decision ▼ Too few choices are considered for major decisions. Missing a more optimal solution may cost time, money, credibility, and perhaps even the whole project. 37 Summary ▼ DAR is a process to make key decisions more objectively and wisely ▼ Making informed, high quality decisions reduces project risk and increases probability of project success ▼ Not every decision requires the use of the DAR process ▼ Resources and templates are available to help you to implement DAR 38 Summary (2) ▼ DAR should be used to make objective decisions on issues which ▼ ▼ ▼ ▼ ▼ involve medium to high risks and have the potential to prevent achievement of project objectives A formal evaluation process reduces the subjective nature of the decision A formal evaluation process has a higher probability of selecting a solution that meets the multiple demands of the relevant stakeholders Guidelines must be established for determining which issues should be subjected to a formal evaluation process The generation and consideration of multiple alternatives early in a DAR process increases the likelihood that an acceptable decision will be made, and that consequences of the decision will be understood Risks associated with the implementation of the selected solutions must be assessed as part of the selection process 39 References ▼ Chrissis, Mary Beth; Konrad, Mike; Shrum, Sandy, CMMI for ▼ ▼ ▼ ▼ Development: Guidelines for Process Integration and Product Improvement, Third Addition; 2011Pearson Education Mizukami, Diane; Northrop Grumman Corp., “DAR Appraisal is Coming,…No Trade Studies Anywhere,…Now What?”; 2008 SEPG Conference Phifer, Bill; EDS; “DAR Basics: Applying Decision Analysis and Resolution in the Real World”, March 10, 2004 Stamnas, Les; “Decision Analysis and Resolution Process Area Workshop”, V1.2, Feb 2010 DAR Process Awareness Training, SSC PAC 2011 40
