Actionable Information from the DevSecOps Pipeline

Because the Particular Operations Command (SOCOM) commander, you might be informed that intelligence has found that an adversary has surprising capabilities. Subsequently, you have to reprioritize capabilities. You inform this system supervisor (PM) to your superior plane platform that the decrease precedence functionality for the whiz-bang software program for sensor fusion that was on the roadmap 18 months from now might want to grow to be the highest precedence and be delivered within the subsequent six months. However the subsequent two priorities are nonetheless vital and are wanted as near the unique dates (three months and 9 months out) as attainable.

That you must know

  • What choices to supply the brand new functionality and the subsequent two precedence capabilities (with lowered functionality) might be offered and not using a change in staffing?
  • What number of extra groups would must be added to get the sensor-fusion software program within the subsequent six months and to remain on schedule for the opposite two capabilities? And what’s the price?

On this weblog put up, excerpted and tailored from a just lately revealed white paper, we discover the choices that PMs make and data they should confidently make choices like these with the assistance of knowledge that’s out there from DevSecOps pipelines.

As in business corporations, DoD PMs are accountable for the general price, schedule, and efficiency of a program. Nonetheless, the DoD PM operates in a special surroundings, serving army and political stakeholders, utilizing authorities funding, and making choices inside a fancy set of procurement laws, congressional approval, and authorities oversight. They train management, decision-making, and oversight all through a program and a system’s lifecycle. They should be the leaders of this system, perceive necessities, steadiness constraints, handle contractors, construct help, and use fundamental administration abilities. The PM’s job is much more complicated in massive packages with a number of software-development pipelines the place price, schedule, efficiency, and danger for the merchandise of every pipeline should be thought of when making choices, in addition to the interrelationships amongst merchandise developed on completely different pipelines.

The aim of the SEI analysis mission referred to as Automated Price Estimation in a Pipeline of Pipelines (ACE/PoPs) is to indicate PMs tips on how to accumulate and rework unprocessed DevSecOps growth information into helpful program-management data that may information choices they need to make throughout program execution. The power to constantly monitor, analyze, and supply actionable information to the PM from instruments in a number of interconnected pipelines of pipelines (PoPs) may also help preserve the general program on observe.

What Information Do Program Managers Want?

PMs are required to make choices nearly constantly over the course of program execution. There are a lot of completely different areas the place the PM wants goal information to make one of the best determination attainable on the time. These information fall into the primary classes of price, schedule, efficiency, and danger. Nonetheless, these classes, and lots of PM choices, are additionally impacted by different areas of concern, together with staffing, course of effectiveness, program stability, and the standard and information offered by program documentation. You will need to acknowledge how these information are associated to one another, as proven in Determine 1.

Determine 1: Notional Program Efficiency Mannequin

All PMs observe price and schedule, however adjustments in staffing, program stability, and course of effectiveness can drive adjustments to each price and schedule. If price and schedule are held fixed, these adjustments will manifest in the long run product’s efficiency or high quality. Dangers might be present in each class. Managing dangers requires gathering information to quantify each the likelihood of prevalence and affect of every danger if it happens.

Within the following subsections, we describe these classes of PM issues and counsel methods during which metrics generated by DevSecOps instruments and processes may also help present the PM with actionable information inside these classes. For a extra detailed therapy of those matters, please learn our white paper.


Price is often one of many largest drivers of selections for a PM. Price charged by the contractor(s) on a program has many aspects, together with prices for administration, engineering, manufacturing, testing, documentation, and many others. This weblog put up focuses on offering metrics for one facet of price: software program growth.

For software-development initiatives, labor is often the only most vital contributor to price, together with prices for software program structure, modeling, design, growth, safety, integration, testing, documentation, and launch. For DoD PMs, the necessity for correct price information is exacerbated by the requirement to plan budgets 5 years prematurely and to replace price range numbers yearly. It’s due to this fact important for PMs to have high quality metrics to allow them to higher perceive total software-development prices and assist estimate future prices.

The DevSecOps pipeline offers information that may assist PMs make choices relating to price. Whereas the pipeline usually doesn’t immediately present data on {dollars} spent, it might feed typical earned worth administration (EVM) programs and may present EVM-like information even when there isn’t any requirement for EVM. Price is most evident from work utilized to particular work gadgets, which in flip requires data on staffing and the actions carried out. For software program developed utilizing Agile processes in a DevSecOps surroundings, measures out there via the pipeline can present information on workforce measurement, precise labor hours, and the precise work deliberate and accomplished. Though clearly not the identical as price, monitoring labor prices (hours labored) and full-time equivalents (FTEs) can present a sign of price efficiency. On the workforce degree, the DevSecOps cadence of planning increments and sprints offers labor hours, and labor hours scale linearly with price.

A PM can use metrics on work accomplished vs. deliberate to make knowledgeable choices about potential price overruns for a functionality or function. These metrics can even assist a PM prioritize work and determine whether or not to proceed work in particular areas or transfer funding to different capabilities. The work might be measured in estimated/precise price, and optionally an estimated/precise measurement might be measured. The anticipated price of labor deliberate vs. precise price of labor delivered measures predictability. The DevSecOps pipeline offers a number of direct measurements, together with the precise work gadgets taken via growth and manufacturing, and the time they enter the DevSecOps pipeline, as they’re constructed and as they’re deployed. These measurements lead us to schedule information.


The PM wants correct data to make choices that depend upon supply timelines. Schedule adjustments can have an effect on the supply of functionality within the area. Schedule can be vital when contemplating funding availability, want for check property, commitments to interfacing packages, and lots of different features of this system. On packages with a number of software program pipelines, it is very important perceive not solely the technical dependencies, but additionally the lead and lag occasions between inter-pipeline capabilities and rework. Schedule metrics out there from the DevSecOps pipeline may also help the PM make choices based mostly on how software-development and testing actions on a number of pipelines are progressing.

The DevSecOps pipeline can present progress towards plan at a number of completely different ranges. A very powerful degree for the PM is the schedule associated to delivering functionality to the customers. The pipeline usually tracks tales and options, however with hyperlinks to a work-breakdown construction (WBS), options might be aggregated to indicate progress vs. the plan for functionality supply as nicely. This traceability doesn’t naturally happen, nonetheless, nor will the metrics if not adequately deliberate and instantiated. Program work should be prioritized, the hassle estimated, and a nominal schedule derived from the out there workers and groups. The granularity of monitoring needs to be sufficiently small to detect schedule slips however massive sufficient to keep away from extreme plan churn as work is reprioritized.

The schedule can be extra correct on a short-term scale, and the plans should be up to date at any time when priorities change. In Agile growth, one of many predominant metrics to search for with respect to schedule is predictability. Is the developer working to a repeatable cadence and delivering what was promised when anticipated? The PM wants credible ranges for program schedule, price, and efficiency. Measures that inform predictability, resembling effort bias and variation of estimates versus actuals, throughput, and lead occasions, might be obtained from the pipeline. Though the seventh precept of the Agile Manifesto states that working software program is the first measure of progress, it is very important distinguish between indicators of progress (i.e., interim deliverables) and precise progress.

Story factors generally is a main indicator. As a program populates a burn-up or burndown chart exhibiting accomplished story factors, this means that work is being accomplished. It offers a number one indication of future software program manufacturing. Nonetheless, work carried out to finish particular person tales or sprints is just not assured to generate working software program. From the PM perspective, solely accomplished software program merchandise that fulfill all situations for carried out are true measures of progress (i.e., working software program).

A standard drawback within the multi-pipeline situation—particularly throughout organizational boundaries—is the achievement of coordination occasions (milestones). Applications mustn’t solely independently monitor the schedule efficiency of every pipeline to find out that work is progressing towards key milestones (often requiring integration of outputs from a number of pipelines), but additionally confirm that the work is really full.

Along with monitoring the schedule for the operational software program, the DevSecOps instruments can present metrics for associated software program actions. Software program for help gadgets resembling trainers, program-specific help gear, information evaluation, and many others., might be important to this system’s total success. The software program for all of the system elements needs to be developed within the DevSecOps surroundings so their progress might be tracked and any dependencies acknowledged, thereby offering a clearer schedule for this system as a complete.

Within the DoD, understanding when capabilities can be accomplished might be important for scheduling follow-on actions resembling operational testing and certification. As well as, programs typically should interface to different programs in growth, and understanding schedule constraints is vital. Utilizing information from the DevSecOps pipeline permits DoD PMs to raised estimate when the capabilities below growth can be prepared for testing, certification, integration, and fielding.


Purposeful efficiency is important in making choices relating to the precedence of capabilities and options in an Agile surroundings. Understanding the required degree of efficiency of the software program being developed can enable knowledgeable choices on what capabilities to proceed creating and which to reassess. The idea of fail quick can’t achieve success except you’ve gotten metrics to shortly inform the PM (and the workforce) when an concept results in a technical lifeless finish.

A needed situation for a functionality supply is that each one work gadgets required for that functionality have been deployed via the pipeline. Supply alone, nonetheless, is inadequate to think about a functionality full. An entire functionality should additionally fulfill the required necessities and fulfill the wants within the meant surroundings. The event pipeline can present early indicators for technical efficiency. Technical efficiency is often validated by the client. Nonetheless, technical efficiency consists of indicators that may be measured via metrics out there within the DevSecOps pipeline.

Check outcomes might be collected utilizing modeling and simulation runs or via numerous ranges of testing inside the pipeline. If automated testing has been carried out, assessments might be run with each construct. With a number of pipelines, these outcomes might be aggregated to provide determination makers perception into test-passage charges at completely different ranges of testing.

A second option to measure technical efficiency is to ask customers for suggestions after dash demos and end-of-increment demos. Suggestions from these demos can present worthwhile details about the system efficiency and its capability to satisfy person wants and expectations.

A 3rd option to measure technical efficiency is thru specialised testing within the pipeline. Stress testing that evaluates necessities for key efficiency parameters, resembling whole variety of customers, response time with most customers, and so forth, may also help predict system functionality when deployed.

High quality

Poor-quality software program can have an effect on each efficiency and long-term upkeep of the software program. Along with performance, there are a lot of high quality attributes to think about based mostly on the area and necessities of the software program. Extra efficiency elements grow to be extra outstanding in a pipeline-of-pipelines surroundings. Interoperability, agility, modularity, and compliance with interface specs are a number of of the obvious ones.

This system should be happy that the event makes use of efficient strategies, points are recognized and remediated, and the delivered product has enough high quality for not simply the first delivering pipeline however for all upstream pipelines as nicely. Earlier than completion, particular person tales should go via a DevSecOps toolchain that features a number of automated actions. As well as, the general workflow consists of duties, design, and opinions that may be tracked and measured for the whole PoP.

Categorizing work gadgets is vital to account for, not just for work that builds options and functionality, but additionally work that’s typically thought of overhead or help. Mik Kersten makes use of function, bug, danger merchandise, and technical debt. We might add adaptation.

The work sort steadiness can present a number one measure of program well being. Every work merchandise is given a piece sort class, an estimated price, and an precise price. For the finished work gadgets, the portion of labor in every class might be in comparison with plans and baselines. Variance from the plan or surprising drift in one of many measures can point out an issue that needs to be investigated. For instance, a rise in bug work suggests high quality issues whereas a rise in technical-debt points can sign design or architectural deficiencies that aren’t addressed.

Usually, a DevSecOps surroundings consists of a number of code-analysis functions that routinely run day by day or with each code commit. These analyzers output weaknesses that have been found. Timestamps from evaluation execution and code commits can be utilized to deduce the time delay that was launched to handle the problems. Subject density, utilizing bodily measurement, purposeful measurement, or manufacturing effort can present a first-level evaluation of the general high quality of the code. Giant lead occasions for this stage point out a excessive price of high quality. A static scanner can even determine points with design adjustments in cyclomatic or interface complexity and will predict technical debt. For a PoP, analyzing the upstream and downstream outcomes throughout pipelines can present perception as to how efficient high quality packages are on the ultimate product.

Automated builds help one other indicator of high quality. Construct points often contain inconsistent interfaces, out of date libraries, or different world inconsistencies. Lead time for builds and variety of failed builds point out high quality failures and will predict future high quality points. By utilizing the length of a zero-defect construct time as a baseline, the construct lead time offers a option to measure the construct rework.

For PoPs, construct time following integration of upstream content material immediately measures how nicely the person pipelines collaborated. Check capabilities inside the DevSecOps surroundings additionally present perception into total code high quality. Defects discovered throughout testing versus after deployment may also help consider the general high quality of the code and the event and testing processes.


Dangers usually threaten price, schedule, efficiency, or high quality. The PM wants data to evaluate the likelihood and affect of the dangers if not managed and attainable mitigations (together with the price of the mitigations and discount in danger consequence) for every attainable plan of action. The dangers concerned in software program growth may end up from inadequacy of the technical resolution, supply-chain points, obsolescence, software program vulnerabilities, and points with the DevSecOps surroundings and total staffing.

Danger outcomes from uncertainty and consists of potential threats to the product functionality and operational points resembling cyberattack, supply schedule, and value. This system should make sure that dangers have been recognized, quantified, and, as acceptable, tracked till mitigated. For the needs of the PM, danger exposures and mitigations needs to be quantified by way of price, schedule, and technical efficiency.

Danger mitigations also needs to be prioritized, included among the many work gadgets, and scheduled. Effort utilized to burning down danger is just not out there for growth, so danger burndown should be explicitly deliberate and tracked. The PM ought to monitor the danger burndown and value ratios of danger to the general interval prices. Two separate burndowns needs to be monitored: the associated fee and the worth (publicity). The associated fee assures that danger mitigations have been adequately funded and executed. The worth burndown signifies precise discount in danger degree.

Improvement groups might assign particular dangers to capabilities or options. Improvement-team dangers are often mentioned throughout increment planning. Danger mitigations added to the work gadgets needs to be recognized as danger and the totals needs to be included in reviews to the PM.

Different Areas of Concern to the Program Supervisor

Along with the normal PM tasks of constructing choices associated to price, schedule, efficiency, and danger, the PM should additionally think about further contributing elements when making program choices, particularly with respect to software program growth. Every of those elements can have an effect on price, schedule, and efficiency.

  • Group/staffing—PMs want to grasp the group/staffing for each their very own program administration workplace (PMO) workforce and the contractor’s workforce (together with any subcontractors or authorities personnel on these groups). Acquiring this understanding is very vital in an Agile or Lean growth. The PMO and customers want to supply subject-matter consultants to the creating group to make sure that the event is assembly the customers’ wants and expectations. Customers can embrace operators, maintainers, trainers, and others. The PMO additionally must contain acceptable workers with particular abilities in Agile occasions and to overview the artifacts developed.
  • Processes—For multi-pipeline packages, course of inconsistencies (e.g., definition of carried out) and variations within the contents of software program deliverables can create huge integration points. It will be significant for a PM to make sure that PMO, contractor, and provider processes are outlined and repeatably executed. In single pipelines, all program companions should perceive the processes and practices of the upstream and downstream DevSecOps actions, together with coding practices and requirements and the pipeline tooling environments. For multi-pipeline packages, course of inconsistencies and variations within the contents of software program deliverables can create huge integration points, with each price and schedule impacts.
  • Stability—Along with monitoring metrics for gadgets like staffing, price, schedule, and high quality, a PM additionally must know if these areas are secure. Even when some metrics are constructive (for instance, this system is under price), traits or volatility can level to attainable points sooner or later if there are broad swings within the information that aren’t defined by program circumstances. As well as, stability in necessities and long-term function prioritization is also vital to trace. Whereas agility encourages adjustments in priorities, the PM wants to grasp the prices and dangers incurred. Furthermore, the Agile precept to fail quick can improve the speed of studying the software program’s strengths and weaknesses. These are a traditional a part of Agile growth, however the total stability of the Agile course of should be understood by the PM.
  • Documentation—The DoD requirement for documentation of acquisition packages creates a PM problem to steadiness the Agile apply of avoiding non-value-added documentation. You will need to seize needed design, structure, coding, integration, and testing information in a fashion that’s helpful to engineering workers answerable for software program sustainment whereas additionally assembly DoD documentation necessities.

Creating Dashboards from Pipelines to Establish Dangers

Though the quantity of knowledge out there from a number of pipelines can get overwhelming, there are instruments out there to be used inside pipelines that can mixture information and create a dashboard of the out there metrics. Pipelines can generate a number of completely different dashboards to be used by builders, testers, and PMs. The important thing to creating a helpful dashboard is to pick out acceptable metrics to make choices, tailor-made to the wants of the precise program at numerous occasions throughout the lifecycle. The dashboard ought to change to focus on metrics associated to these altering aspects of program wants.

It takes effort and time to find out what dangers will drive choices and what metrics may inform these choices. With instrumented DevSecOps pipelines, these metrics are extra available, and lots of might be offered in actual time with out the necessity to look ahead to a month-to-month metrics report. Instrumentation may also help the PM to make choices based mostly on well timed information, particularly in massive, complicated packages with a number of pipelines.
