With an annual information technology budget of about $20 billion, and tens of billions more budgeted for technology embedded in sophisticated ‘weaponry, the Departinent of Defense (DOD) relies heavily on software Intensive systems to support military operations and associated business funetions, such as logisties, personnel, and financial enanagement One ‘important determinant of the quality of these systems, and thus DOD'S nission performance, is tne quality of the processes used to develop, ogre, and engineer them Recognizing the importance ofthese processes

to producing systems that perform as intended and meet cost and schedule commitments, successful public and private organizations have alopted and implemented softwareystems process improvement (SPD programs!

“This report is part of our response to your request to compare and contrast OD information technology practices with leading practices In particular, ‘you asked us to review DOD components (military services and Defense agencies) SPI management activities to ensure that DOD is taking the necessary steps to continuously strengthen its software and systems ‘development, acquisition, and engineering processes As agreed with Your

“offices, our objectives were to (1) compare selected DOD components! SPL ‘programs against Carnegie Mellon University’s Software Engineering Institutes (SED IDEAL!™ model, which isa recognized best practices model, 2) determine how these components have approached ‘management of their SPI programs, and (3) determine what DOD-wide efforts are under way to promote and leverage the components? SPI ‘rograms The components that we selected were the Departments ofthe “Army, Air Force, and Navy the Marine Corps; the Defense Logistics Agency (DIA); and the Defense Finance and Accounting Service (DFAS)

[Because Army, Navy and Air Force do not manage SPI centrally and have delegated SPI responsibilty to their respective subordinate organizational ‘units, we selected atleast two ofthe largest ofthese uits within each service to review Accordingly all references in this report tothe respective services’ SPI programs refer only to the subortinate units that we

reviewed, We performed our work from March through December 2000, in saccordarice with generally accepted government auditing standards (See appendix I for details of our objectives, scope, and methodology including the specific service units reviewed.) DOD provided us with written

comments on a draft of this report These comments are summarized in the "Agency Comments and Our Evaluation" section ofthis letter and are reproditced in fallin appendix

Background OD maintains a fore of about $ milion military and eliian personnel worldwide To protet the secunty of the United States, the departn relies on a complex array of computerdependent and mutually supportive ‘organizational components, inching the military services and Defense

agencies It also relies on a broad array of computer systems, including

“weapons aystems, command and control ystems, satelite ystems, inventory management systems, Gnatcialeystems, personnel ystems, ‘payment systems, and others Many of these systems in tum are connected ‘with systems operated by private contractors other government agencies, and international organizations

DOD's ability to effectively manage information technology i critical to its hy to accomplish its mission, fs reliance on software-intensive systems to support operations related to intelligence, survellance, security, and

sophisticated weaponry—along with financial management and other business functions —ill only increase asthe department modernizes and responds to changes in traditional concepts of warfighting

“The scope of DOD's information technology inventory is vast: over 1.5 rillion computers, 28,000 systems, and 10,000 computer networks Further, ‘many of DOD's most important technology projects continue to cost more

than projected, take longer to produce, and deliver less than promised AS aresul, we have designated DOD systems development and modernization ‘efforts as a high-risk area*

"The quality ofthe processes involved in developing, acquiring, and

‘engineering software and systems has a significant effect onthe quality of the resulling products Accordingly, process improvement programs can Increase product quality and decrease product costs Public and private ‘organizations have reported significant returns on investment through such

rocess improvement programs SEI has published reports of benefits rallzed through process improvement programs For example, SEI reported in 1905" that a major defense contractor implemented a process Improvement program in 1088 and by 1905 had reduced its rework costs from about 40 percent of project cost to about 10 percent, increased staff productivity by about 170 percent, and reduced defects by about 75, percent According to a 1900 SBI report, a software development ‘contractor reduced its average deviation from estimated schedule tie {raat Dip a Det Pil War 100 Peace Rapa and ‘isl Tar 001 Peformance Pra (GADNSIAD- 188, ane 9 28)

‘rom 112 percent to 6 percent between 1088 and 1906 During the same ‘period, SEI reported that this contractor reduced its average deviation ‘rom estimated cost from 87 percent to minus 4 percent

‘To aid organizations attempting to initiate and manage SPI programms, SEL has published a best practices model called IDEAL,™ hich defines systematic five phase, continuous process improvement approach, with &

‘concurrent sixth element addressing the program management tasks spanning the five phases*(see figure 1)

‘igure 1: Simplified Diagram of he IDEAL™ Mode Initiating Leveraging Diagnosing > |Establishing Program Management

+ Initiating: During this phase, an organization establishes the ‘management structure ofthe process improvement program, defines and assigns roles and responsibilities, allocates initial resources, {develops a plan to guide the onganization through the first three phases ‘ofthe program, and obtains management approval and funding Two key ‘organizational components ofthe program management structure

established during this phase are a management steering group and a ‘software engineering process group (SEPG) Responsibility for this, hase ests with senior management

Trang 9

> Diagnosing: During this phase, the SEPG appraises the current level oF ‘process maturity to establish a baseline capability against which to ‘measure progress and identifies any existing process improvement inliatses, The SEPG then uses the baseline to identify weaknesses and target process improvement activities It also compares these targeted activities with any ongoing process improvement activities and

reconciles any differences Responsibility for this phase rests primarily with lie managers and practitioners

+ Establishing: During this phase, the SEPG prioritizes the process Improvement activities and develops strategies for pursuing them It then develops a process improvement action plan that details the activities and strategies and includes measurable goals for the activities and metrics for monitoring progress against goals Also during this phase, the resources needed to iruplement the plan are committed and training is provided for technical working groups, who will be

responsible for developing and testing new or improved processes Responsihity for this phase resides primarily with line managers and practitioners

‘+ Acting: During this phase, the technical working groups, formed under the esiablishing phase, create and evaluate new and improved processes, Bvaluation of the processes is based on pilot tests that are formally planned and executed, If the tests are successful, the working -sroups develop plans for orgaaization-wide adoption and

Insitutionaliztion, and once approved, execute them Responsibility {or this phase resides primarily with line managers and practitioners + Leveraging: During this phase, results and lessons learned from earlier

phases are ansested and applied, an appropriate, to enhance the structures and plans of process improvement programs Responsibility {or this phase rests primarily with senlor management

“The models sixth element, continuous program management, specifies ‘management structures ad tasks for planning, organizing, directing, staffing, and monitoring the program Responsibility for this element rests

ach phase of the IDEAL™ model contains several recommended tasks, Appendix I, which deseribes our objectives, seope, and methodology, Identifies al tasks for each phase

Results in Brief ‘The DOD components that we reviewed vary in how they compare to SE's IDEAL™ model In particular, the Air Force, Army, and DFAS generally satisfed the models recommended tasks, as did certain Navy units However, DLA, the Marine Comps, another Navy units dd not Specifically, DLA does not have an SPI program, although during the course of our review the DLA Chief Information Officer stated that she intends to establish one Further, although the Marine Corps is performing many SPL activities, core tasks associated with an effective SPI program, such asa plan of action or dedicated resources to implement recommended

Improvements, are missing Finally, certain Navy units also do not have SPI programs aligned with the IDEAL™ model, although one is perforng a few of the model's recommended asks

‘The four components with SPI programs (Army, Air Force, DFAS, and parts ofthe Navy) are using different management strategies for directing and controlling their respective programs Nonetheless, all components with SPI programs report that they have realized benefits in product quality and ‘productivity For example, DRAS uses a centralized management approach land reports that is SPI program has helped decrease development costs about one-third lower than those of similar organizations In contrast, the Army uses a decentralized approach and also reports tht the SPI programm for one ofits organizational units has helped it almost double its

‘productivity in developing software

DOD-wide activities to promote and leverage component SPI programs do rot exist Aecording fundamental to continuous process improvement While wo organtzational 10 the IDEAL model, leveraging SPI experiences is “unite within the Office ofthe Secretary of Defense (OSD) that have {important leadership roles to play in department software and system,

processes are both taking steps almed at strengthening DOD software, ‘these steps do not specifically include SPL In particular, OSD des not have initiatives under way or planned to determine where in DOD SP! programs do and do not exist so that steps can be taken to promote programs in ‘component units where they do not, such asa DLA Similarly, actions do

"Rötexis to share informtion across the department about the experiences ‘of successful SPI programs, such as those within the Army, Navy, Alr Force, ‘nud DFAS, According o OSD officials, uncertainty about the casts versus

Trang 11

‘benefits of SPI, resource constraints, and other priorities have precladed such a focus Without such actions, DOD is missing opportunities to realize potential SPI benefits in all DOD components To adress this, we are ‘making recommendations to the Secretary of Defense

DOD provided written comments on a dealt ofthis report In commenting, DOD agreed that SP practices should be used and encouraged and that information about best practices should be shared, However, DOD stated

that itis premature at this point to mandate SPI programs throughout the ‘department, as we recommend, and that ihas established a working group to review how best to proceed While we believe that sufilent bases ‘curently exist to mandate SPI, particulary in ight of the evidence inthis

report on (I) components that are not implementing SPI in the absence of a ‘mandate and 2) the benefits being reported by components that are {implementing SP, we do not view DOD's desire to await the results ofits ‘working group as beng unreasonable or inconsistent with our recommendations Components’ SPI Program Alignment With SEI IDEAL™ Model Varies

‘The Army and Air Force units that we reviewed, as well as DFAS and two of the four Navy units have long-standing SPT programs that satisfy almost every task recommended inthe IDBAL™ model (se table I fora sumenary

‘ofhow cach component and te units, i applicable, compared to the ‘model, For exaniple, in 1096 the Secretary of the Army mandated that all, software development, acquisition, and maintenance activities establish ‘SPI programs Further the Amy requires that its software activities ‘continually improve their process maturity and has set maturity goals for all ofits unit, Army regulations also mandate that contractors be

‘evaluated for software process maturity Moreover, the two specific units ‘within the Army that we reviewed have SPI management structures, plans, And dedicated resources In addition, these units have continuously evolved in software and system process maturity through many years of asesaing their baseline process capabilites, implementing new andl Improved process inilatives, reassessing process maturity, and Implementing lessons learned Both Army units satisfy all IDBAL™ tasks

In contrast, DLA, the Marine Corps and two of the Navy's four units that ‘we reviewed do not perform important IDEAL™ model tasks In particular, DLA currently doesnot satisfy any of the model's recommended tas ‘According to DLA offical, it had an SPI program prior to 1988, but at that time the program was terminated to reduce costs During (C10 stated that the agency plans to begin a new SPI program and has taken our review, DLAs

‘capability, However, tis not using this baseline as a basis for implementing ‘ecommercd improvements, or does it have an SPI plan or dedicated resources for these activities As such, the likelihood of the Marine Corps? process improvement initiatives producing desired results is diminished "Two of the four Navy software/systems units that we revieeedl also do not have SPI programs that are aligned withthe IDEAL! model To thele credit, however, one has recently taken the first step toward initiating a programa and the other has activities under way that could form the beginnings of ‘rogram (See appendix IV for more detailed results on each ofthe ‘components that we reviewed.)

‘The four components that have SPI programs—Amy, Ait Force, DFAS, and parts of the Navy—have differen approaches for directing and controling ther respective programs, raging from centralized to highly decentralized; each, however, repors positive results For example, DFAS has a

‘centralized approach, wit ts headquarters all SP acivties In contrast, the Arty, Alt Force, and Navy have office directing and controlling decentralized approaches to SPI program management, The Army, which bbgan its SPI program centrally, has since delegated SPL responsiblity to its commands, which—in the case ofthe two commands we reviewed—have further delegated SPI program management to their respective

software!systems units Sinilany the Air Force units that we reviewed further delegated SP! management to their respective sotware/systems units The Navy commands fellow different approaches-—one manages its ‘program centrally and the other has delegated SPI management to its ‘sofware/systems units

Despite diferent approaches, each DOD component/unit with an SPL rogram reports postive effects on software/systems quality: DFAS, for ‘example, reports that its SPI program has reduced its cost to deliver software Navy software activity reports reduced cost, improved product quality, to about one-third less than organizations of sinilar size One and a7: return on its SPI investment An Ary activity reports that it has almost doubled its productivity in writing software for new systems ‘because of improvements made under its SPI program (See appends 1V

oth OSD organizational units have efforts under way aimed at improving some aspects of DOD's ability to develop and acqire software and systems For example, they have established teams to conduct software Acquisition maturity assessments and established a software collaborators group They also are collecting software metrics and establishing training, for managers

However, OSD has no SPI actions under way or planned, such as issuing policy and guidance on SPI programs; determining where in DOD SPL prograns do and do not exis; promoting the establishment of programs in

‘component units, such as DLA, where they do not exist; and sharing ‘knowledge across DOD about the experiences of reportedly successful SPL programs, such as those within the Anny, Air Force, DFAS, and pars of the Navy According to OSD officals, uncertainty about the costs versus ‘benefits of SP, resource constraints, and other priorities have precluded such afocus However, as stated earlier inthis report, various

‘organizations including some DOD components, report positive returns on {nvestinent from SPI programs that arghe for SP being treated as a funding proxi

We also recommend that the Secretary direct the Assistant Secretary for Command, Control, Communications, ‘determine the components compliance with the SPI policy and and Intelligence to (1) annually

‘Agency Comments and ln writen comments on a draft ofthis report, the Deputy Assistant

Our Evaluation agreed withthe reports message that SPI practices should be used and Secretary of Defense for Command, Control, Communications, and Intelligence, whois also the DOD Deputy Chief Information Officer (C10), fencouraged, and that information about SPI practices should be shared ‘among DOD components To this end, and since receiving a draft ofthis

report, the Deputy CIO stated that the Under Secretary of Defense

(Acquisition, Technology, and Logistics) has established a working group" {hat s, among other things, to develop a plan for implementing SPI

According tothe Deputy CIO, this plan willbe ready for internal review in ‘April 2001

Further, the Deputy CIO stated that a January 2001 revision to DOD Regulation 50002-R” represents a policy step toward addressing software improvement by including in the regulation a section on software

‘management, According tothe Deputy CIO, while this section does not specifically call for an SPI program, the regulation provides guidance for Improving software by using, for example, SEI Capability Maturity Model level 3 or ts equivalent for major acquisition programs with procurement costs in excess of $219 billion *

Trang 17

Tnlight ofthe above, the Deputy CIO stated that DOD agreed with our recommendation to establish and promote a means for sharing SPI lessons learned and best practices knowledge throughout DOD, and add that a DOD steering group,” which was chartered during the course of our review, has been assigned responsiblity for this function, However, the Deputy ClO disagreed with our recommendation that DOD issue apoliey to ‘mandate SPI programs for all DOD components and their relevant

activities According to the Deputy CIO, establishing a policy requiring oF otherwise directing DOD components that donot have SPI programs to lunplement them would be premature at this time because there are insufficient data to Justify the sole use ofthe SELIDBAL™ model and that ‘unless a specific model were used, compliance with such a policy oF dlrective would be problematic Therefore, the Deputy CIO stared a ‘decision regarding the issuance of DOD-wide policy mandating the {implementation of SPI programs would not be made until the work group ‘reports its results and develops its plan for implementing SPL At this point and without the work group's findings, according to the Deputy ClO, {issuance of SPI guidance (as opposed to *policy”) would be “a more Deneficial approach.”

In our view, the Deputy C10’ comments are not inconsistent with our recommendations, and our point of disagreement appears to center around sump the timing of actions rather than the recommended actions

‘hemselves Specifically, while we continue to believe that suficent bases currently exist for issuance of a DOD SPI policy requirement, especially in light ofthe evidence in our report that (1) without this requirement not all ‘components are implementing SPI and (2) those components that are currently implementing SP1 are reporting substantial benefits, its reasonable for DOD to await its work group's results before malang & {ecision on how to proceed Further, we agree with the Deputy CIOS ‘comment that there ae insicient cata to ustfy citing in DOD poliey the SELIDBAL™ model a the single model for SP Our report recognizes that notall ofthe DOD components that we cited as having effective SPL programs not prescribe are using the same model Asa result, our recoznmendations did a specific SPI model Instead, we recommended that in developing SPI policy and associated guidance, DOD should consider basing this dance on the SEI IDEAL" model as well a the positive

Regarding the Deputy CIO comment that DOD has recently revised! DOD Regulation 50002-R to inchude guidance for improving software

management through the use of, for example, SEI Capability Maturity Model leve 3, we note that level 3 requirements include performance of process improvement practices that are expanded upon bythe SEI IDEAL model Additionally, we note that the regulation does not apply ta all DOD software/system programs but, rather, only to aequisition

Appendix 1

Objectives, Scope, and Methodology

‘Our objectives were to (1) compare selected DOD components? SPI ‘programs against SETs IDEAL™ model, which is a recognized best ‘Prictices model; (2) determine how these components have approached ‘management of thelr SPI programs and what program results they are reporting; and (3) determine what DOD-wide efforts are under way to promote and leverage the components’ SPI programs The selected ‘components include all four services—Army, Air Force, Navy, Marine CCorps—and two DOD agencies that have lage, software intensive system

rodemization programs under way-—the Defense Finance and Accounting Service (DFAS) and the Defense Logistics Agency (DLA)

‘To address the first objective, we reviewed the components respective information technology strategic plans as well as available SPI policies, fuidance, and program documentation, and interviewed headquarters officials from each component Using this information, we frst ascertained ‘whether SPI programs or activities existed for a component, and 50, How they were organized and stractured For the components in which we

{ound SPI programs or activities, we then identified the units within the ‘components responsible for implementing those programs and activities Ininstances in which these responsibilities were decentralized (Army, Alt Force, and Navy), we worked with component headquarters and command officials to select atleast two units in each component (@) had mussions involving both software intensive weapons and business that collectively systems and (2) were reeporuable for the largest percentages of software and systems development, acquisition, and engineering activities within ‘each comporient Table 2 shows the DOD conponents ane

reviewed program progress and performance reports and discussed program accomplishments with responsible officials to identify examples ‘of SPI benefits We then analyzed each components SPI program results in ‘elation to its program management approack to determine whether any

patterns were evident We did not independently validate components reported accomplishments and benefits,

‘To adress the third objective, we interviewed responsible component officials, reviewed supporting records and documentation, and visited Internet sites to identify SPI program best practices and lessons leamed, along with what efforts are being made to share these with other activities and components throughout the department We also identified two offices ‘within the Office ofthe Secretary of Defense (OSD) that have responsibility and activities underway relating to the advancement of software and system management practice in the department—the Office of the Deputy Under Secretary of Defense for Acquisition, Technology, and Logistics; and the Office ofthe Assistant Secretary of Defense for Command, Control,

Communications, and Intelligence For each office, we analyzed

documentation describing their respective ongoing and planned activities and interviewed officials n doing so, we focused on identifying any activities that specifically promoted and leveraged SPI programs ancl activities under way throughout DOD We also discussed with SPI program officials in each component their awareness of the OSD efforts,

We performed our work at Army headquarters, the Pentagon, Arlington, ‘Virginia; and interviewed officials and reviewed documentation from the Communications Electronics Command Software Engineering Center at Fort Monmouth, New Jersey; and the Aviation and Missile Command

The following are GAO's comments on the Department of Defense letter dated March 2, 2001

GAO Comments 1 We disagree Sufficient policy requirement, especially in ght of the evidence in our report that bases currently exist for issuance of a DOD SPI (CE) without this requirement not all components are implementing SPL ‘and ©) those components that are currently implementing SPI are reporting substantial benefits, Nevertheless, DOD's decision to await, ‘an OSD work group's results before making a decision on how to

proceed isnot unreasonable o inconsistent with our position, 2, See response to comment I

3 We disagree Oversight is an important part of policy implementation, and! without such oversight, DOD would incur significant risk that thê policy would not be implemented Further, establishing a baseline ‘measure to determine compliance does not require the implementation ‘fa speeific model, The intent of our recommendations isto establish a policy requiring SP that recognizes, as our report recognizes, that there {smore than one model for doing so effectively

Description of SEI Capability Maturity Models

Sinee 1984, the Software Engineering Institute (SET) has worked to

improve management of software/systems productivity and quality

primarily by addressing problems in acquiring, developing, engineering, or ‘enhancing softwarelsystems through a series According to SEI, an organization's process capability provides a means of| of capability maturity models

predicting the most likely outcome of the next software/systems project undertaken; process maturity impltes thatthe productivity and quality ‘resulting from an organization's software/systems processes can be improved as maturity of the processes increases The IDEAL™ model is ‘based on lessons leamed from SEl experiences aswell as from SBI projects| ‘lating to software process capability and maturity For example, during the initiating phase ofthe IDEAL™ model, general SPI program goals are defined, and this deSinition could be in terms of capability maturity model levels In the diagnosing phase, IDEAL™ recommends developing an ‘organization process maturity baseline; SE's capability maturity model— based appraisal is one way of establishing this baseline

‘The fst of these capability maturity models, the Software Capability ‘Maturity Model® (SW-CMM@), was designed to assist organizations in ‘improving sofware development and maintenance processes In this :model, software process maturty—ranked froma low ofleval Ito ahigh of

level 5—serves as an indicator of the likely range of software cost, schedule, and quality that can be expected to be achieved by projects developed within an organization (See figure 2.)

individuals and groups planning and managing software acquisition activites

‘+ The Systems Engineering CMM@ describes the essential elements ofa ‘organization's systems engineering process and provides a reference for ‘comparing actual systenns engineering practices against these elements "The model addresses the process aspects of systems engineering and the product development portion of the life cycle, This model was a collaboration of several organizations including SEL

+ In 1997 a tam led by DOD, in conjunction with SEI, govemment, and industry, concentrated on developing an integrated framework for ‘maturity models and associnted products The result was the CMM Integration™ (CMMI) which is intended to provide guidance for Improving an organization's processes and the ability to manage the evelopment, acquisition, and maintenance of products and services, hile reducing the redundancy and inconsistency caused by using standalone models

‘The CMO™ combines earlier models from SEI and the Electronic Industries Alliance? into a single model for use by organizations pursuing ‘enterprise-wide process improvement, However, the prototype CMMI

‘does not include the acquisition features ofthe SA-CMM® because the team wanted to focus fist on the development process A CMMI that includes coverage for acquiring software intensive systems is currently being developed Additional disciplines may also be covered Ultimately, ‘the CMM i to replace the models that have been its starting point

management systems The Army budgeted about $3 billion on {information technology during fiscal year 2000

The Army has assigned responsibility for information systems to the Army Materiel Command (AMC) Several major subcommands function under AMC Three of these major subcommands—the Conumunications- Electronics Command (CECOMD, the Aviation and Missile Command (AMCOM), and the TankeAutomotive Comamand—are responsible for the acquisition, development, engineering, and maintenance of information technology for the Army We reviewed the Army's SP activities at CECOM and AMCOM

(CECOM has assigned responsibility for information ystems to its Sofware Engineering Center (SEC) The center, located at Fort Monmouth, New Jersey s supported by several software/systems activites located across ‘the United States The center is responsible for overseing about 85 percent of the Army's ystems, including (1) command, contro,
