View source for Assessment and Control

The purpose of Systems Engineering Assessment and Control (SEAC) is to provide adequate visibility into the [[Project (glossary)|project’s]] actual technical progress and [[Risk (glossary)|risks]] with respect to the technical [[Plan (glossary)|plans]] (i.e., [[Systems Engineering Plan (SEP) (glossary)|Systems Engineering Management Plan (SEMP)]] or [[Systems Engineering Plan (SEP) (glossary)|Systems Engineering Plan (SEP)]], and subordinate plans).  The visibility allows the project team to take timely preventive action when disruptive trends are recognized or corrective action when performance deviates beyond established thresholds or expected values. [[Acronyms|SEAC]] includes preparing for and conducting reviews and audits to monitor performance.  The results of the reviews and [[Measurement (glossary)|measurement]] analyses are used to identify and record findings/discrepancies and may lead to causal analysis and corrective/preventive action plans.  Action plans are implemented, tracked, and monitored to closure.  (NASA 2007, Section 6.7) (SEG-ITS, 2009, Section 3.9.3, 3.9.10) (INCOSE, 2010, Clause 6.2)  (SEI, 2007)

==SE Assessment and Control Process Overview==

The SEAC process includes determining and initiating appropriate handling strategies and actions for findings and/or discrepancies that are uncovered in the enterprise, infrastructure, or life cycle activities associated with the project.  Analysis of the causes of the findings/discrepancies aids in the determination of appropriate handling strategies.  Implementation of approved preventive, corrective, or improvement actions ensures satisfactory completion of the project within planned technical, schedule, and cost objectives.  Potential action plans for findings and/or discrepancies are reviewed in the context of the overall set of actions and priorities in order to optimize the benefits to the project and/or organization.  Interrelated items are analyzed together to obtain a consistent and cost effective resolution.	

The [[Acronyms|SEAC]] process includes the following steps:
*Monitor and review technical performance and resource usage against plan
*Monitor technical risk, escalate significant risks to the project risk register and seek project funding to execute risk mitigation plans
*Hold technical reviews and report outcomes at the project reviews
*Analyze issues and determine appropriate actions
*Manage actions to closure
*Hold a Post Delivery Assessment (also known as a Post Project Review) to capture knowledge associated with the project (this may be a separate technical assessment or it may be conducted as part of the Project Assessment and Control process).  

The following activities are normally conducted as part of a [[Project (glossary)|Project]] Assessment and Control process:
*Authorization, release and closure of work
*Monitor project performance and resource usage against plan
*Monitor project risk and authorize expenditure of project funds to execute risk mitigation plans
*Hold Project reviews
*Analyze issues and determine appropriate actions
*Manage actions to closure
*Hold a Post Delivery Assessment (also known as a Post Project Review) to capture knowledge associated with the Project 

Examples of major technical reviews used in SEAC are shown in Table 1 from (DAU 2010):

==Linkages to Other Systems Engineering Management Topics==
The Systems Engineering assessment and control process is closely coupled with the [[Measurement]], [[Planning]], [[Decision Management]], and [[Risk Management]] processes.
The [[Measurement]] process provides indicators for comparing actuals to plans. [[Planning]] provides estimates and milestones that constitute plans for monitoring, and the project plan with measures used to monitor progress. [[Decision Management]] uses the results of project monitoring as decision criteria for making control decisions.

==Practical Considerations==
Key pitfalls and good practices related to SEAC are described in the next two sections.

===Pitfalls===

Some of the key pitfalls encountered in planning and performing SE Assessment and Control are shown in Table 2 (SEBoK Original): 

{| 
|+'''Table 2. Major Pitfalls with Assessment and Control.''' (SEBoK Original)
! Name
! Description
|-
| No [[measurement (glossary)|Measurement]]
| 
*Since the assessment and control activities are highly dependent on insightful measurement information, it is usually ineffective to proceed independent of the measurement efforts - what you get is what you measure.
|-
| "Something in Time" Culture
| 
*Some things are easier to measure than others - for instance, delivery to cost and schedule. Don't focus on these and neglect harder things to measure like quality of the system, Avoid a "something in time" culture where meeting the schedule takes priority over everything else, but what is delivered is not fit for purpose and drives rework into the project.
|-
| No Teeth
| 
*Make sure that the technical review gates have "teeth". Sometimes the project manager is given authority (or can appeal to someone with authority) to over-ride a gate decision and allow work to proceed, even when the gate has exposed significant issues with the technical quality of the system or associated work products. This is a major risk if the organization is strongly schedule-driven; it can't afford the time to do it right, but somehow it finds the time to do it again (rework).
|-
| Too Early Baselining 
| 
*Don't baseline requirements or designs too early. Often there is strong pressure to baseline system requirements and designs before they are fully understood or agreed, in order to start subsystem or component development. This just guarantees high levels of rework.

===Good Practices===
Some good practices gathered from the references are shown in Table 3 (SEBoK Original):

{| 
|+'''Table 3. Proven Practices with Assessment and Control.''' (SEBoK Original)
! Name
! Description
|-
| Independence
| 
*Provide independent (from customer) assessment and recommendations on resources, schedule, technical	status, and risk based on experience and trend analysis.
|-
| Peer Reviews
|
*Use peer review to ensure the quality of work products before they are submitted for gate review
|-
|Accept [[Uncertainty (glossary)|Uncertainty]]
|
*Communicate uncertainties in requirements or designs and accept that uncertainty is a normal part of developing a system.
|-
| Risk Mitigation Plans
|
*Do not penalize a project at gate review if they admit uncertainty in requirements - ask for their risk mitigation plan to manage the uncertainty.
|-
|Just In-Time Baselining
|
*Baseline requirements and designs only when you need to - when other work is committed based on the stability of the requirement or design. If work has to start and the requirement or design is still uncertain, consider how you can build robustness into the system to handle the uncertainty with minimum rework. 
|-
|Communication 
|
*Document and communicate status findings and recommendations to stakeholders. 
|-
|Full Visibility 
|
*Ensure that action items and action-item status, as well as other key status items, are visible to all project participants.
|-
|Leverage Previous Root Cause Analysis
|
*When performing root cause analysis, consider root cause and resolution data documented in previous related findings/discrepancies.
|-
|[[Concurrent (glossary)|Concurrent]]  Management 
|
*Plan and perform Assessment and Control concurrently with the activities for [[Measurement]] and [[Risk Management]]. 
|-
|Lessons Learned and Post-Mortems 
|
*Hold post delivery assessments or post project reviews to capture knowledge associated with the project - for instance, to augment and improve estimation models, lessons learned databases, gate review checklists.
